Start with the all-in monthly cost
Mortgage principal and interest are only part of the housing bill. Property taxes, homeowners insurance, mortgage insurance, HOA dues and maintenance can materially change what a home costs each month.
Separate approval from comfort
A lender evaluates whether you meet its underwriting standards. Your household also needs to judge whether the resulting payment leaves enough room for food, transport, childcare, retirement saving, debt payments and emergencies. Those are different questions.
Use current rates for scenario testing
Freddie Mac’s national average 30-year fixed rate was 6.65% on August 20, 2026. Use current market rates only as a starting scenario; your quote may be higher or lower depending on the loan and borrower profile.
Cash to close can be the binding constraint
Your down payment is not the only upfront cash need. Closing costs, prepaid taxes and insurance, moving costs and an emergency reserve should be planned separately. CFPB materials show these items on the Loan Estimate and Closing Disclosure.
Use the Plandime calculator
A borrowing decision is easier to judge when you compare the monthly payment with the total cost.
