"How much house can I afford" has a generic internet answer — some multiple of income, a 28% rule, a calculator on a lender's site with fields for a dozen things a buyer hasn't decided yet. What actually helps a buyer in the moment, standing in a house they're excited about, is someone doing the real math for this specific price, right now.
Down payment changes more than the down payment
A bigger down payment doesn't just mean a bigger check at closing — it directly reduces the loan amount, which reduces the interest cost every single month for as long as the loan lasts. Showing a buyer the actual dollar difference between 10% and 20% down, on the specific home they're looking at, makes the tradeoff concrete instead of abstract.
Interest rate is the number that moves the most
Buyers often anchor on the home price and forget the rate is doing more work in their monthly number. Re-running the same home price at a slightly different rate is often the fastest way to show why "waiting for rates to drop" or "locking in now" actually matters in dollars, not just in headlines.
A first-year estimate, not a mortgage pre-approval
A quick affordability estimate is genuinely useful for a real-time conversation, but it's not full loan amortization — no PMI, no property tax, no insurance, no principal paydown schedule. Being upfront about that distinction is what keeps the estimate useful instead of setting a number a buyer later feels misled by.
Use the template instead of doing the math out loud
The Home Affordability Calculator already has this structure — home price and down payment percentage rolling up into loan amount and estimated first-year interest, recalculating live as you adjust the numbers. Open it in FLYNT Sheets next time a buyer asks the question, and once they've settled on a price range, price the listing itself with the CMA Template.
