Down payment assistance tools and calculators
Five free tools that answer the questions a down payment assistance file actually turns on: what the loan limit is in your county, whether you meet the common eligibility rules, which programs you may match, what the assistance costs you over time, and how much cash you still need at closing.
Quick answer: Which calculator should you use?
Start with affordability to find the price range your income and debts support, then use the payment and closing-cost tools to pressure-test a specific home, the repayment tool to see what an assistance second costs over time, and the refinance tool if you already own and are weighing a rate, cash-out or consolidation move.
TL;DR
- Affordability first, then payment and closing costs on a real address.
- The repayment tool models grant, forgivable, deferred and repayable seconds.
- All figures are estimates, not quotes or offers of credit.
Quick questions
- Are the results a quote?
- No. They're estimates for planning. A quote requires a full application and a credit review.

What these tools are for
Down payment assistance turns a savings problem into an eligibility problem, and eligibility is made of numbers you can check before you talk to anyone: the county income cap, the county purchase-price limit, the FHA or conforming loan limit, the minimum borrower contribution, and the cash you still need on the table at closing.
Each tool below answers one of those questions with published data or with figures you supply. None of them requires an account, and none of them returns an approval — an approval needs verified income, verified assets, a property and a credit review.
The order most buyers should use them in
Buyers who work these in sequence arrive at a lender with a realistic price range and the right documents. Buyers who open one calculator in isolation almost always plan around the wrong constraint.
- Check the county limits — the FHA one-unit limit caps the first mortgage; the program purchase-price limit is set separately by the housing finance agency and is often lower.
- Test yourself against the common rules — ownership history, occupancy, homebuyer education, the income cap, borrower contribution and credit review.
- Find the programs that fit — the finder matches your answers against the registry and links each result to the administering agency's own page.
- Price the structure — the assistance calculator shows what a grant, a deferred second and a repayable second each do to your monthly obligation.
- Compare before you accept — the comparison page puts the four structures against each other over three, five and ten years.
Where the numbers come from
Loan limits come from the HUD CHUMS forward-limit file for the current calendar year and the FHFA conforming loan limit announcement. Area median prices are HUD's published figures for the county. Program details come from the administering agency's own published documents, each linked on the program page.
Nothing on this site is generated or estimated where a published figure exists. Where a figure is an estimating convention rather than a published value — the closing-cost percentage band, for example — the tool says so on the page.
- Loan limits: HUD CHUMS annual forward-limit file, refreshed for each calendar year.
- Conforming limits: FHFA annual conforming loan limit announcement.
- Income and purchase-price limits: the administering housing finance agency for the county.
- Program terms, funding status and repayment structure: the agency's own program document.
- Market context: federal mortgage-market data, refreshed on a published schedule.
Every tool on this site
- DPA Finder
Ten questions on location, income, household size and buyer status, matched against every program in our registry. Returns potential matches with the official program source for each one.

The full monthly cost of a price — principal, interest, your state's published property tax rate, insurance, mortgage insurance and HOA — plus the purchase price your income supports at a chosen debt-to-income ceiling.
- Repayment and recapture calculator
What you would owe back on a grant, forgivable second, deferred second, repayable second or shared-appreciation award if you sell or refinance in any given year.

Tool questions
Are these down payment assistance tools free to use?
Yes. Every tool on this page runs in your browser, and none of them requires an account or a fee. The finder asks for contact details only when you choose to see your matched program list.
Do the calculators give me a real quote?
No. They produce estimates for planning, using figures you enter and published limits. A quote requires a full application, verified income and assets, a property and a credit review, and is delivered as a Loan Estimate.
Which tool should I start with?
Start with the county loan limit lookup and the eligibility explainer if you are early. Once you know your county limits and where you sit against the common rules, run the finder and then the cash-to-close estimator against a real price.
Can I use these tools outside Florida and Colorado?
Yes, the research and calculators are available nationwide. Simply Approved Mortgages LLC originates residential mortgages only in Florida and Colorado, so outside those states the tools are educational and you should work with a lender licensed where the property sits.
