Built for UK Investors

Analyse One Deal. Compare Three Investment Strategies.

Most property calculators only analyse one strategy. The Deal Stack-Up Calculator compares the same property as a Flip, Buy-to-Let and BRRR investment, helping you identify the strategy that offers the strongest financial outcome.

📈

Flip Analysis

Estimate purchase costs, refurbishment costs, finance costs and potential profit before committing to a deal.

🏡

Buy-to-Let Analysis

Calculate rental cash flow, mortgage costs and cash-on-cash return to assess long-term investment performance.

♻️

BRRR Analysis

Estimate refinance proceeds, capital left in the deal and overall BRRR performance using realistic UK assumptions.

⚖️

Compare Strategies

View all three investment strategies together and quickly identify which approach best suits the property.
