Why the condo affordability calculator matters
HOA fees are treated as housing expense by lenders, so a $500 monthly due can cut around $75,000 off the price you qualify for. This page turns that decision into a handful of inputs you can defend in a budget review: volume, unit cost, rate of adoption, and time. The output is a planning baseline, not a promise — it tells you whether the idea deserves a vendor quote, a pilot, or a pass.
- • Biggest swing factor: the HOA due, which reduces payment capacity dollar for dollar
- • Second-order factor: other monthly debt
- • Often ignored: the mortgage rate
What actually changes the answer
the HOA due, which reduces payment capacity dollar for dollar moves this number first, then other monthly debt. Run a conservative case and an upside case before you commit. If the maths only works in the upside case, treat it as a time-boxed test with a kill date rather than a line in next year's plan.
What to do with the result
Add the HOA due to your monthly debt input to see the real approvable price.

FAQ
What does the condo affordability calculator work out?
It applies Max payment = min(36% × monthly income − debts, 28% × monthly income); Loan = payment × [(1 − (1 + i)^−n) ÷ i]; Price = loan + down payment to the values you enter for gross annual income, existing monthly debt payments, down payment / cash available, interest rate, loan term (years). HOA fees are treated as housing expense by lenders, so a $500 monthly due can cut around $75,000 off the price you qualify for.
How accurate is this condo affordability calculator?
You must include HOA dues in the monthly debt field yourself; the model does not know the building. Replace the defaults with your own invoice, usage export, payroll data, statement, or vendor quote before making a commitment — the maths is exact, so the answer is only as good as the inputs you feed it.
Which input should I stress-test first?
the HOA due, which reduces payment capacity dollar for dollar. Re-run with a pessimistic value for it; if the decision flips, that assumption is the thing you need real data on before signing anything. After that, check other monthly debt and the mortgage rate.
Which scenario should I start from?
Start with the preset closest to your situation — cautious budget, today's numbers, stronger position — then edit the sliders. Presets are realistic starting points, not benchmarks to match, and every change updates the result instantly.
What should I do after running the numbers?
Add the HOA due to your monthly debt input to see the real approvable price. A useful planning benchmark to compare against: HOA dues commonly run $200–$700 a month and count against your debt ratios.
Can I share or save this calculation?
Yes. Your inputs are written into the page URL, so copying the link shares the exact scenario you are looking at — the person who opens it sees the same numbers. You can also export the inputs and results to CSV or PDF from the result card and keep it with the rest of your workings.
