Bridge-to-Let Calculator

Bridge-to-Let Calculator: use this tool to model the financial structure of a property purchase funded initially by bridging finance and later refinanced onto a buy-to-let mortgage.

It allows you to test purchase costs, refurbishment spend, SDLT, bridging interest, rental yield, return on investment, cash released on refinance and the remaining cash position. It is not a lending decision, but it can expose weak assumptions before a case is presented to funders.

What this tool calculates
Bridging loan cost, including interest, fees and total facility cost
Purchase costs and refurbishment spend, including SDLT
Buy-to-let refinance assumptions, including LTV, rental coverage and monthly payment
Net rental yield on the stabilised property
Return on investment and cash released on refinance

A note on accuracy

We have taken care to refine the underlying logic of this analyser. However, property finance calculations are sensitive to assumptions about purchase costs, works cost, finance terms, valuation, rental income and refinance criteria. The results should therefore be treated as estimates rather than guarantees. Actual costs, rates and returns will depend on the specific lender, property and circumstances of each transaction. The calculator does not replace lender underwriting or professional advice. If you would like to discuss a live case, please get in touch directly.
