FAQ
- How does the affordability calculator estimate the available down payment?
- The tool subtracts the entered tax-and-reserve percentage from available cash to estimate money left for a down payment. With cash of 300000 and a 10% reserve, 270000 remains. These are budget assumptions rather than an assessment of actual taxes or a lender's minimum down-payment requirement. Review expected expenses and the contract separately, because changing the reserve percentage can materially change the apparent purchasing capacity without changing your real obligations.
- How does a monthly payment budget determine an estimated borrowing amount?
- The borrowing estimate uses the present value of equal monthly payments, based on the affordable payment, annual rate, and term. A 20-year term gives 240 periods, and dividing the annual rate by 12 gives the monthly rate. The output is a mathematical result for those inputs. Lender review, existing debts, policy restrictions, and additional costs still need separate consideration before treating the amount as available financing.
- Is the affordability calculator's maximum home price a recommended purchase price?
- The displayed maximum price is available cash plus modeled borrowing, not a recommendation or property valuation. For example, 270000 of down-payment funds plus a modeled 730000 loan gives a 1000000 budget. Actual decisions also need living expenses, transaction costs, contract terms, and lending approval. The arithmetic does not evaluate a home's value or determine how much financial risk a household can comfortably accept over the loan term.
