Reading the results

Cash left in the deal

What stays tied up after the refinance pays you back. The lower the better: a deal that returns all your money is the "perfect" BRRR, but under 25% of the project cost is a sound result.

ROI

A year's cash flow divided by the cash left in. Aim for 15% or more. If no cash is left in and the rent still covers the costs, the return is effectively unlimited.

Monthly cash flow

Rent, less the new mortgage interest and running costs. It should be positive at a realistic rent, and still positive if rates rise.

Getting good inputs

  • Start from a realistic purchase price and refurb quote.
  • Be conservative with the value after works (GDV): it sets how much the refinance raises.
  • Always carry a contingency buffer.
  • Check local rents before you rely on them. Our town guides have Tees Valley figures.

For estimation and education only, not financial advice. Figures are illustrative and vary with your circumstances and the specific deal. Take independent advice from a qualified solicitor, accountant and mortgage broker before you invest.
