The 20% Myth: What A Down Payment Really Is And How Much You Might Need

Ask a room full of renters how much they need to save to buy a home, and a lot of them will say "20%." It's one of the most stubborn myths in real estate. Twenty percent down has real benefits, but it's not a universal requirement, and believing it can keep people renting longer than they need to.

Let's break down what a down payment is, the general minimums for common loan programs, and the other cash you'll want to plan for.

What a Down Payment Is

Your down payment is the part of the purchase price you pay upfront from your own funds (or approved sources like gifts and assistance). The lender finances the rest.

If you buy a home and put a certain percentage down, your loan covers the remaining percentage. That ratio is called loan-to-value, or LTV, and it matters. A lower LTV means less risk for the lender, which can affect your pricing, your mortgage insurance and which programs are available to you.

Your down payment also becomes your starting equity, your ownership stake in the home from day one.

General Minimums by Loan Type

These are general program guidelines from the agencies that set them. Individual lenders can require more, and guidelines change.

Conventional Loans: As Low as 3% on Certain Programs

Fannie Mae's HomeReady mortgage allows down payments as low as 3% for eligible borrowers whose income is at or below 80% of the area median. Other conventional programs have their own minimums. Under 20% down usually means private mortgage insurance.

FHA Loans: 3.5% in Most Cases

HUD states FHA's minimum required investment is 3.5% in most cases. FHA guidelines tie the maximum financing to credit score. Under HUD's current Single Family Housing Policy Handbook 4000.1 (section II.A.2.b.i), borrowers with a minimum decision credit score of 580 or higher are eligible for maximum financing, while scores from 500 to 579 are limited to 90% LTV (that is, at least 10% down). Lenders may set higher minimums.

VA Loans: No Down Payment for Eligible Borrowers

The VA says VA-backed purchase loans often require no down payment as long as the sales price isn't higher than the appraised value. A funding fee may apply.

USDA Loans: No Down Payment for Eligible Borrowers

USDA Rural Development's Section 502 program offers 100% financing for eligible low- and moderate-income buyers in eligible rural areas, per USDA.

So Why Do People Talk About 20%?

On a conventional loan, 20% down is the line where PMI typically isn't required, according to the CFPB. The CFPB also notes you could receive a lower interest rate with 20% down. Those are real advantages. But they have to be weighed against how long it takes to save that much, and how much cash you'd have left over after buying.

Where Down Payment Money Can Come From

You don't have to save every dollar yourself. Depending on the program, acceptable sources may include:

• Your savings and checking, which lenders typically want to see documented with bank statements
• Gifts from family, usually documented with a gift letter and a paper trail
• Down payment assistance (DPA) grants or second loans. The Idaho Housing and Finance Association offers down payment assistance through approved lenders.
• Retirement account withdrawals or loans, which have tax and long-term trade-offs worth discussing with a tax professional

HUD notes FHA's 3.5% minimum can come from gifts, second mortgages and grants through assistance programs. Fannie Mae says HomeReady allows funds from gifts, eligible grants and Community Seconds.

One tip: avoid moving money around or making large unexplained cash deposits in the months before you apply. Lenders need to source your funds, and a clean paper trail makes underwriting smoother.

Beyond the Down Payment: Cash to Close

The down payment isn't the only check you'll write. Plan for:

• Closing costs: lender fees, appraisal, title insurance, recording fees and more. These are the upfront costs of getting the loan and transferring ownership.
• Prepaids and escrow deposits: initial homeowners insurance and property tax deposits into your escrow account.
• Earnest money: a deposit made when your offer is accepted, usually credited toward your costs at closing.
• A cushion: money for moving, a lawnmower, window coverings and the first surprise repair.

Your Loan Estimate shows "Estimated Cash to Close," which rolls the down payment and closing costs together. The CFPB's Loan Estimate explainer suggests checking that you'll have enough cash on hand to cover it.

Finding Your Number

Instead of chasing a percentage, try this:

1. Decide on a comfortable monthly payment. Use our payment calculator to see how different down payments change the monthly total, including PMI when you put down less than 20%.
2. Ask a lender which programs fit you. The minimum you can put down depends on the program you're eligible for.
3. Keep reserves. Putting every dollar into the down payment can leave you exposed. Many buyers keep an emergency fund after closing.
4. Look into assistance. Check Idaho Housing's programs and ask lenders which assistance options they work with.

Quick FAQ

Is a Bigger Down Payment Always Better?

Not always. A bigger down payment lowers your loan amount and may cut or eliminate PMI, but it also ties up cash you might need for emergencies or repairs. Balance both.

Can the Seller Pay My Down Payment?

Generally no, though sellers can sometimes contribute toward closing costs within program limits. Your agent and lender can explain the rules for your loan type.

Does Earnest Money Count Toward My Down Payment?

Usually it's credited toward your down payment or closing costs at closing. Confirm with your agent and lender.

How Do I Find Down Payment Assistance in Idaho?

Start with the Idaho Housing and Finance Association's homebuyer page, and ask lenders which assistance programs they offer.
