Higher mortgage rates
Increase the interest-rate assumption and see how financing costs affect monthly cash flow.
BUY-TO-LET STRESS TEST
Test whether a property deal still works when conditions worsen.
Model rate rises, voids, rent reductions and repair overruns before a promising headline yield becomes an expensive commitment.
Stress-test the assumptions that affect cash flow
A buy-to-let calculation is only as useful as the assumptions behind it. Property Action OS keeps the base case visible while showing how a less favourable scenario changes the monthly result.
Rental void periods
Allow for weeks without rent rather than assuming twelve uninterrupted months of income.
Lower achievable rent
Reduce the expected rent to test whether the deal depends on an optimistic estimate.
Repair overruns
Add an unexpected repair allowance and assess whether sufficient margin remains.
Stress tests are illustrative and are not lender affordability assessments or financial advice. Verify finance, rent, costs, tax and property condition before committing.
Connect downside testing to due diligence
Use the property investor deal room to record the evidence and professional checks needed before commitment.
