What breaks first when the deal gets harder?

Compare the base case with a deliberately tougher scenario before relying on projected cash flow or lender coverage.

Property & loan

Use the written rate from the loan scenario you are screening.

Rent & housing costs

Use the lender-eligible rent from the lease or appraisal when available.

Program thresholds vary. Test the requirement in the lender’s written terms.

Investor reality check

These costs do not change the lender-style rent ÷ PITIA ratio. They show whether the property still produces cash after operating costs.

Example assumptions only. Replace these numbers with your own.

The downside scenario is deliberately simple

Rent falls 10%, vacancy rises five percentage points, the financing rate rises 0.75 points, and maintenance and capital reserves each rise two points. It is a consistent screen, not a forecast of the next recession.

Look for margin, not just survival

A property that barely remains above zero has little room for a major repair, longer turnover or an insurance increase. Compare downside cash flow with your own emergency reserve and risk tolerance.

Change the assumptions that matter locally

Remote investors should pay particular attention to management, leasing and turnover costs. Replace every percentage with quotes and evidence from the exact market and property type.
