How to Figure Out Your Down Payment on a House

Start With Your Loan Type, Not the 20% Rule

Most buyers make one mistake: they treat 20% down as a requirement. It's not, and it hasn't been for years. That number comes from before mortgage insurance programs existed in their current form.

The real data says otherwise. The 2024 NAR Profile of Home Buyers and Sellers shows the median first-time buyer put down 9%. Across all buyers, the median was 18% - still under the supposed rule.

Your real floor is the minimum for your loan type:

- Conventional: 3% minimum

- FHA: 3.5% with a credit score of 580 or higher, 10% with a score of 500-579

- VA: 0%

- USDA: 0%

- Jumbo: typically 10-20%

Once you know that floor, stop asking "can I afford 20%?" Ask this instead: how much above the minimum fits my monthly budget and my savings cushion? That's the real math, and it comes down to two things: what PMI costs you, and what a bigger down payment saves you in interest.

The Real Math: PMI, Interest Rates, and a $400,000 Example

Put down less than 20% on a conventional loan and you pay private mortgage insurance. Here's what that actually costs: PMI runs 0.2% to 2% of your loan amount annually. On a $350,000 home with 3% down, that's roughly $140-$280 per month. Conventional PMI cancels automatically once you hit 22% equity. FHA is stricter: put down less than 10% and the mortgage insurance lasts the life of the loan.

A bigger down payment also buys a better rate. Freddie Mac research shows borrowers with 20% or more down have historically gotten rates roughly 0.125-0.25% lower.

Run the numbers on a $400,000 home and 20% down beats 5% down by roughly $145,000 over 30 years: a $60,000 difference in the down payment itself, plus about $76,720 less in total interest.

So why put down less? One word: liquidity. A smaller down payment keeps your emergency fund intact, gets you into a home years sooner, and leaves money available for repairs and moving costs. Neither answer is wrong. The right down payment is the one that fits both your monthly payment target and the reserves you refuse to drain.

What This Means When You're Selling a Florida Home

If you're on the selling side, this math changes how you should read offers. A buyer bringing 3.5% down on an FHA loan is not a weak buyer - they are the statistical norm. NAR's data says the median first-time buyer puts down 9%. What actually determines whether a financed buyer closes is whether their financing has been vetted: pre-underwriting, appraisal expectations, and a lender who has already seen their file.

That vetting step is where Cash Flow Deals fits. You choose between the Fast Cash Offer, where we buy your house as-is and close, and the Premium Cash Offer, where a pre-approved FHA or conventional buyer we already have, ready to go, pays more and buys directly from you. With Premium, your home may be listed through Silver Door Realty, a licensed Florida brokerage, with a licensed agent and scheduled showings. If you own a Florida house and want to compare both offers for your property, start with your Florida selling options.

We cover repair costs, and we figure out a way, so nothing comes out of your pocket. With Premium, only what your buyer's lender requires gets fixed; repair costs are settled from the sale proceeds, from our share. With Fast Cash, you sell as-is without making repairs. The number is agreed before any work starts, and it changes only if you agree. The one exception: if something structural surfaces that was not visible or disclosed before we signed — foundation issues, hidden moisture, old wiring, cast-iron drain failure — we re-cost it and bring the number back to you. You decide. You can walk away. We disclose what we know at offer time so this almost never happens.

Here's how you compare your two offers with Cash Flow Deals:

1. Share your address and basic property details with Cash Flow Deals and get your Fast Cash Offer and Premium Cash Offer numbers within 24 hours. You can review those numbers before a Premium buyer completes loan underwriting or an appraisal.

2. Compare both offers against your mortgage payoff and moving timeline. With Premium, your buyer signs a new contract directly with you, title transfers directly to them, and their lender funds the purchase. We are paid as a separate line item on the closing statement. If your buyer's loan falls through, that is our problem, not yours, and you can still take the Fast Cash Offer at its own number alongside your Premium Cash Offer choice.

3. Review the existing close-in-45-days-or-less option with us and help pick your date. Your closing timing depends on the offer you choose and, with Premium, your buyer's lender requirements.
