Questions to Ask a Property Sourcer (UK): 17 Checks Before You Pay

A good sourcing relationship should feel like clarity, not pressure. If a deal is genuine, basic verification will make it stronger, not “kill it”.

This checklist helps you separate confident marketing from real evidence, before you commit money or momentum.

Ask these questions early and you will avoid the most expensive mistake in sourcing: paying first, and thinking later.

Property sourcing can save you time. It can also cost you thousands.

Because the biggest risk with sourced deals isn’t the sourcing fee itself, it’s what happens after you pay it:
you stop asking hard questions, you start trusting the pack, and you inherit risks you didn’t verify.

Most investors don’t get burned because they paid £2,000 to a sourcer.
They get burned because they paid £2,000 and then bought a deal with weak numbers, unclear legal position, or an exit that never existed.

This checklist is designed to stop that.

These are the questions to ask before you pay any fee, so you can quickly tell whether you’re looking at a genuine opportunity or a well-presented mistake.

Before paying any property sourcing fee in the UK, ask for proof of exclusivity, seller/agent confirmation, comparable sales, realistic refurb scope, and clear fee terms in writing. Verify legal basics like title restrictions, lease terms, licensing requirements, and whether you can view the property. A legitimate sourcer answers directly with evidence, not vague assurances or pressure to pay.

Quick rule before you start: the fee must buy value, not information

You should be able to point to the exact advantage you’re buying and explain it in plain English. If the value feels vague, unmeasurable, or based on confidence rather than proof, treat that as a sign the fee isn’t earned.

The purpose of this rule is simple: it keeps you paying for outcomes, not opinions.

If the sourcer is only giving you a Rightmove link and a rent estimate, you are not paying for a deal.

You are paying for packaging.

If you’re new to this, start with how property deal sourcing works in the UK so you understand where sourcers add value and where investors usually get misled.

A sourcing fee is only justified when it buys at least one of these:

• real access (before the listing goes live)
• speed (time-sensitive opportunity)
• reduced uncertainty (real due diligence already done)
• strong margin (deal survives stress testing even if assumptions change)

If none of those are true, don’t pay.

Now let’s go through the exact questions.

Section 1: Access and deal control questions (is this even real?)

Before you talk ROI, refurb, or rent, you need to confirm the deal actually exists and you have a real route to secure it. A surprising number of investors pay fees for “opportunities” that are already gone, already widely circulated, or impossible to control.

This section helps you test access, availability, and viewing rights upfront, because without control, everything else is just theory.

1) Is this deal exclusive, and what does exclusive mean here?

You’re not asking this to be difficult, you’re asking because “exclusive” is one of the most misused words in sourcing. If it’s been broadcast to a long list, your leverage disappears and the price usually rises fast.

A real exclusive should come with clarity on who else has access and what stops the seller from accepting another offer tomorrow.

This is one of the most important questions you can ask.

“Exclusive” can mean:

• only shared with you
• shared with 30 people on a list
• a public listing that the sourcer found first

What you want: clarity on who has seen it, and whether it’s still available.

Follow-up question:
“How many investors has this been sent to already?”

2) Can you confirm the property is still available today?

This question protects you from paying for a deal that’s already effectively sold. In active markets, “still available” can change within hours, especially if the sourcer has sent it to multiple buyers.

If they can’t verify availability with a real contact, you’re not getting an opportunity, you’re getting a stale lead.

It sounds basic. It saves you from wasting time.

If the sourcer cannot confirm availability, you’re already behind the market.

Follow-up question:
“Who is the selling agent or vendor contact, and can you introduce us?”

A legitimate sourcer should not be afraid of you speaking to the agent or vendor.

3) Can I view the property before I pay any fee?

A viewing is where reality shows up: layout issues, damp, neighbour problems, street quality, and hidden works that never make it into a sourcing pack. If you’re forced to pay first, you’re being moved into commitment before you have enough information to make a proper decision.

Even if you love the numbers, you should still confirm the asset with your own eyes, because your exit depends on what the property is, not what the spreadsheet says.

This one is non-negotiable.

If you can’t view before paying, you’re being asked to commit money based on someone else’s photos and assumptions.

Follow-up question:
“What is the viewing process and timeline?”

4) What is the seller’s situation and why are they selling?

A deal usually exists because someone wants certainty more than they want the last penny. When you understand the selling driver, you can judge whether there’s real room to negotiate, and whether the timeline being suggested is believable.

If the story is vague or keeps changing, assume the sourcer doesn’t control the deal, and treat every claim about “urgency” or “discount” as unproven until you verify it.

Motivation matters because it affects price flexibility and timelines.

You don’t need personal details, but you do need the commercial reason:

• probate sale
• repossession
• tired landlord
• relocation
• portfolio disposal

If the sourcer can’t explain the situation, they might not have a real relationship, just a listing link.

Section 2: Sourcing Fee questions (how do I avoid getting trapped?)

A sourcing fee is often where investors lose leverage, because once you’ve paid, your emotional commitment increases even if the deal quality doesn’t. That’s why the fee stage needs structure, not vibes.

This section helps you confirm what you’re paying for, what protection you have if the deal collapses, and whether the terms are fair. If the fee is unclear or the paperwork is sloppy, treat that as a warning about everything else.

5) What exactly does your fee cover?

You’re not being “cheap” by asking this, you’re being commercially disciplined. A real service can be described clearly, including what you get, when you get it, and what support is included after introduction.

If they can’t explain the deliverables without hiding behind buzzwords, assume the value is thin and the fee is doing the heavy lifting.

You want a clear statement like:

• access to the opportunity
• introduction to vendor/agent
• negotiation support
• due diligence pack
• project support (if included)

If the answer is vague, your protection is weak.

6) Is the fee refundable under any conditions?

This question tells you whether the sourcer shares any of the risk, or whether you’re carrying it all from day one. Even a limited refund policy can signal professionalism and confidence in the opportunity.

If the answer is “never refundable” no matter what happens, your only protection is your verification. That means you should demand stronger proof and slower decision-making, not faster.

Most fees are not refundable, but you must understand the terms.

Ask specifically:

• refundable if property is unavailable
• refundable if title issue blocks purchase
• refundable if the seller pulls out
• refundable if finance is impossible

If there is no refund option, you need stronger evidence before paying.

7) Is your fee a reservation fee, sourcing fee, or finder’s fee?

The label matters because it changes what you can reasonably expect in return. A “reservation fee” implies some level of control and time protection, while a simple sourcing fee may only cover the introduction.

If the wording is messy or keeps shifting, that’s usually a sign the terms are designed for the sourcer’s protection, not yours. Clear definitions prevent misunderstandings and stop you paying for something that was never guaranteed.

These are not the same thing.

If it’s a “reservation fee”, ask:

• What exactly is being reserved?
• For how long?
• What happens if the seller accepts another offer?

If it’s just a sourcing fee, ask:

• What are you delivering for the fee?

8) Can I see your terms in writing before paying?

Written terms are what protect you when the deal changes, delays, or disappears. If everything is verbal, you have no clear agreement on what you paid for or what happens if the transaction fails.

A professional sourcer won’t hesitate to share terms upfront, because good operators expect scrutiny. If they resist paperwork, assume they’re relying on pressure and ambiguity, not process.

Never pay based on a WhatsApp message. If you’re unsure whether paying a sourcing fee is ever worth it, read the 5 situations where sourced deals actually make sense before you commit.

You need the terms and conditions:

• fee amount
• payment method
• refund rules
• what you receive
• liability limitations

If the sourcer refuses to put terms in writing, walk away.

Section 3: Numbers questions (is this actually profitable?)

Your goal in this section is to turn every key number into something traceable. If the sourcer can’t show where the figures come from, you should treat them as marketing, not evidence.

This is also where you protect yourself from thin-margin deals. When the margin is tight, even small errors in GDV, refurb, or rent can erase the profit completely.

Use these questions to confirm the deal works in a normal scenario, not just the best case.

9) How did you calculate the end value (GDV), and what comps support it?

This is the part where most sourced deals fall apart, because numbers are easy to present and hard to prove. A “great ROI” often depends on one optimistic assumption: the end value, the refurb cost, or the achievable rent.

Your job is not to catch small errors, it’s to confirm the deal still works when assumptions are realistic. If the margin is thin, even minor inaccuracies can wipe it out.

Treat every figure in a sourcing pack as a starting point, not a conclusion. Until you can trace the number back to evidence, it’s just a claim.

These questions force the deal into the open, so you can decide based on facts, not confidence.

This is where weak deals get exposed.

You want:

• comparable sales addresses
• sold prices
• dates
• distance from property
• same property type and condition

If the comps are “best on the street” or from 2 years ago, your GDV is not safe.

10) What’s your refurb estimate based on, and what does it include?

Refurb is where most “great deals” quietly die, because it’s the easiest number to underestimate and the hardest one to fix later. A light refresh and a full renovation can look similar in photos, but they produce completely different costs and timelines.

Your goal here is to turn a single figure into a clear scope, so you can judge whether the margin is real or just assumed.

A refurb number without scope is meaningless.

Ask for:

• list of works assumed
• standard vs full renovation
• kitchens, bathrooms, roof, electrics
• contingency included or not

Even better: ask whether the estimate has been reviewed by a contractor.

11) Have you included stamp duty, finance costs, and selling costs in your ROI?

This question is designed to expose “headline ROI” deals that only work because half the costs are missing. A deal can look strong on paper, then turn average once you add finance friction, buying costs, and exit fees properly.

If the sourcer can’t show a full cost breakdown, assume the profit figure is inflated until you rebuild the numbers yourself.

Many packs show “profit” but ignore:

• stamp duty surcharge
• bridging interest
• arrangement fees
• legals
• broker fees
• marketing and selling fees
• voids and maintenance

Ask the sourcer:
“Can you show me the full cost schedule you used?”

If they can’t, run your own numbers.

12) What is the worst-case scenario if costs rise or the sale takes longer?

This is where you find out whether the deal has real resilience, or whether it only works in perfect conditions. Delays, cost creep, and softer rents are normal in property, so your model should expect them, not fear them.

If a small change wipes out the profit, the risk isn’t “market conditions”, it’s that the deal was too tight to begin with.

Good investors don’t invest in best-case scenarios.

Ask:

• what happens if refurb rises 15%
• what happens if sale takes 4 months longer
• what happens if rent is £100 less than projected

If the deal collapses under small stress tests, it’s not a deal.

Section 4: Legal and compliance questions (what can block the deal?)

This section is the difference between a deal that completes smoothly and one that turns into months of delay, extra fees, or a failed purchase. The legal side rarely looks exciting in a sourcing pack, but it’s where the biggest hidden risks live.

Your aim is not to become a solicitor, it’s to spot early warning signs that could affect lending, resale, or the strategy you’re planning. If the legal position is unclear, your numbers are automatically unreliable.

Ask these questions early, because once you’ve paid fees and instructed solicitors, walking away gets emotionally and financially harder.

13) Can I see the Land Registry title, and have you checked restrictions or charges?

This isn’t about doing the solicitor’s job early, it’s about avoiding obvious deal-killers before you invest time and money. Restrictions, access rights, and unusual charges can affect whether you can refinance, sell, or even use the property the way you planned.

If the sourcer can’t show the basics upfront, assume the risk is unknown until proven otherwise, not “probably fine”.

This is basic due diligence, but it catches major issues early.

Ask:

• any restrictions
• any charges
• any overage clauses
• any access issues

If the sourcer says “solicitors will check later”, that’s fine, but you still need visibility now.

If you want a deeper breakdown of what solicitors can uncover, use this legal due diligence checklist for UK property deals before you commit funds.

14) If it’s leasehold, what are the service charge, ground rent, and lease length?

Leasehold problems often don’t show up in the photos or the ROI headline, but they can hit you every year through higher charges and unexpected major works. A deal that looks strong as a freehold can become weak fast once the ownership structure is understood.

If the sourcer can’t answer these basics, pause and get the lease details early, because leasehold surprises are expensive and they reduce your exit options.

Leasehold can destroy margins quietly.

Ask:

• current service charge
• ground rent amount and escalation
• lease term remaining
• major works planned
• any Section 20 notices

If they don’t know, don’t assume it’s fine.

15) Does this strategy require licensing, and have you confirmed it?

Licensing is one of the fastest ways for a “high yield” deal to turn into a slow, expensive headache. If you don’t confirm it upfront, you can end up with extra fees, upgrade requirements, and delays that wipe out your cashflow.

If you’re planning an HMO-style strategy, use the official HMO licence guidance to confirm whether the property needs licensing in that area before relying on the rent figure.

Make sure the strategy is actually permitted for that address, not just “commonly done in the area”.

Many rent projections ignore licensing reality:

• selective licensing
• additional licensing
• HMO licensing
• planning rules for HMOs

Ask:
“Can you show me the council source or confirmation?”

16) What’s the EPC position now, and what upgrades might be required?

EPC is not just a compliance box, it’s a cost forecast. A low rating can translate into real spending on insulation, heating, glazing, or other upgrades before your rental strategy performs the way you expect.

If the upgrade path is unclear or unrealistic for the building type, treat that as a margin risk, not a minor detail.

Even if rules change, EPC is still a major cost driver for landlords.

Ask:

• current EPC rating
• what upgrades might be needed
• whether the property can realistically reach compliance levels

If EPC upgrades wipe out your yield, the deal is weaker than it looks.

Section 5: Process questions (can I actually complete?)

Even a profitable deal can become a bad decision if the process doesn’t match your reality. Completion timelines affect everything: finance costs, survey scheduling, solicitor workload, and whether you can secure the asset before someone else does.

This section helps you spot deals that are “technically good” but practically impossible to execute on time. If the seller expects a fast exchange and you’re not set up for it, you’ll waste time and potentially lose money on upfront steps.

A legitimate sourcer should be able to explain the timeline clearly and show you how the transaction will move from offer to exchange. If they can’t, assume there are delays and unknowns you haven’t been told.

17) What is the timeline from offer to exchange, realistically?

Timelines are not just admin, they change the cost of the deal. The longer it drags, the more you pay in finance, holding costs, and opportunity cost, especially if you’re using bridging or you need quick certainty.

You’re also testing whether the seller’s expectations are realistic. If they want exchange in 14 days but the legal pack is incomplete, the timeline is a fantasy and you’ll be the one under pressure.

A good sourcer will give you a clear route to completion with the key steps mapped out. A weak one will just repeat “it needs to move fast” without explaining how.

If the deal requires speed and you can’t meet the timeline, the deal is not for you.

Ask:

• seller timeline
• auction deadlines (if relevant)
• access for surveys
• how fast the seller wants exchange

18) Who controls the solicitor process?

You should control this.

Never allow a sourcer to force:

• a specific solicitor
• a specific broker
• a specific contractor

You can take recommendations, but control must remain yours.

19) Have you done this type of deal yourself, or are you only distributing it?

This question separates operators from marketers.

If they have experience, they can:

• explain risks early
• answer questions clearly
• show realistic cost expectations

If they don’t, you must be more cautious.

Section 6: Red flag questions (the ones that expose bad sourcing)

These questions are designed to cut through sales language and expose whether the sourcer is offering a real opportunity or just trying to create urgency. A good deal can handle direct scrutiny, because the value is obvious and evidence-backed.

This section also helps you spot the pressure tactics investors fall for: vague answers, constant time pressure, and “trust me” logic. If the sourcer becomes defensive when you ask basic questions, that’s usually your signal to step back.

Use these red flags as your exit trigger. It’s better to lose a “deal” than buy a problem you could have avoided in one conversation.

20) Why is this a deal, in one sentence?

A genuine deal has a simple reason:

• mispricing
• motivated seller
• forced sale
• value-add opportunity
• planning upside

If the answer is:
“because it cashflows” or “because ROI is high”, that’s not a reason.

That’s a result, and it may not be real.

21) What would make you walk away from this deal?

A good sourcer knows risk.

If they say “nothing”, that’s a red flag.

You want someone who can name:

• legal title issues
• structural problems
• valuation down
• unrealistic refurb costs
• weak exit demand

If a sourcer avoids basic questions or relies on urgency, check the biggest deal sourcing traps UK investors fall into and compare the red flags.

22) Can I speak to past investors you’ve worked with?

Social proof matters, but it must be real.

Ask for:

• testimonials with names
• business pages
• repeat buyer evidence

If everything is anonymous screenshots, be cautious.

To verify the opportunity properly, use this due diligence checklist to confirm a sourced deal is real before you pay any fee or instruct solicitors.

The one-page checklist

If you want the whole thing in a quick decision format, here it is:

Before paying any sourcing fee, confirm:

• you can view the property
• the agent/vendor is real and contactable
• the deal is still available today
• comps support the GDV
• refurb estimate has scope
• full costs are included (stamp, finance, selling)
• legal basics are visible (title, lease if needed)
• licensing and EPC risks are understood
• fee terms are written and clear
• no pressure tactics are being used

If those aren’t met, don’t pay.

Final thought: your questions are your investor protection

The most dangerous sourced deals are the ones that “feel professional”.

Nice branding is not due diligence.

The smartest investors don’t avoid sourcing.
They avoid weak verification.

If a sourcer is genuine, these questions won’t offend them.
They’ll respect you for asking.
