Underwrite the Deal and Cash Cushion
A first investment needs a full property budget, not only an estimated mortgage payment. For a rental, start with supportable collected rent and include vacancy, management, maintenance, taxes, insurance, association dues, utilities and major replacement allowances. Separate recurring costs from initial repairs and closing expenses.
Build a lender qualification worksheet and an investor cash-flow worksheet. A rent-to-PITIA ratio can meet a program rule while cash after other expenses is weak. Do not count taxes or insurance twice if they are already in PITIA. If you plan to self-manage, consider whether the property would still work with paid management or the value of your own time.
Obtain inspection findings and estimates for near-term capital needs. A low purchase price can conceal a roof, HVAC or foundation obligation that consumes reserves immediately. Evaluate a lower-rent case and one significant repair. Keep a cushion beyond any contractual reserve minimum if the operating plan requires it. Compare projected cash return with capital invested using a labeled denominator, while recognizing that appreciation and tax benefits are separate and uncertain. A good first deal is one you can operate and fund under realistic conditions, not one that only works when every assumption is favorable.
Worked example
Monthly rent is $2,200 and PITIA $1,650. Vacancy $110, management $176, repairs $110 and replacement allowance $100 leave $54 planned monthly cash. The lender ratio is about 1.33, but annual planned cash is only $648 before additional surprises or investor tax.

Put it into practice
Build a conservative rental budget and attach inspection-based repair estimates. Recalculate with 10% lower rent and a $3,000 unexpected repair. Distinguish closing cash from cash left afterward. If the downside cannot be funded, revise the offer, financing or reserve plan before proceeding.
