The down payment is the number buyers save toward for years — and the number most often misunderstood, because a threshold from one corner of mortgage lending has hardened into a supposed rule. There is no 20% requirement. There are program minimums, a mortgage-insurance line, and a trade between cash now and cost every month. Here is the honest shape of each.
Each major program sets its own floor. Conventional loans go as low as 3% down for qualifying buyers — the first-time-buyer and low-to-moderate-income programs such as HomeReady and Home Possible live at that level — while a standard conventional loan commonly asks 5%. FHA loans require 3.5% down for a borrower with a credit score of 580 or higher, and 10% down at a score of 500 to 579. VA loans require no down payment from eligible service members, veterans, and qualifying surviving spouses, and USDA loans likewise offer 0% down to eligible borrowers buying in eligible areas. Individual lenders may ask more than a program's floor, and eligibility is the lender's call — but the floor itself is a program fact, not a custom. On a $400,000 home, the floors read: $12,000 at 3%, $14,000 at 3.5%, $20,000 at 5%, and $0 on an eligible zero-down loan.
Twenty percent is real — it is just not a gate. On a conventional loan, putting down less than 20% means paying private mortgage insurance (PMI): a monthly charge that protects the lender, not the buyer. PMI is temporary on a conventional loan — the borrower can ask to cancel it when the loan reaches 80% of the home's original value, and it ends automatically at 78% on the standard schedule. FHA loans carry mortgage insurance (MIP) on their own terms, which do not follow the conventional 80% pattern. So 20% is the level at which one monthly charge disappears — a genuine saving, weighed honestly against the years of waiting it can take to get there.
A smaller down payment is not free money and a larger one is not a virtue; they are two prices for the same house. Less down means a larger loan, a higher monthly payment, mortgage insurance for a time, and more interest over the loan's life — in exchange for buying sooner and keeping cash reserves a household may need more than it needs a smaller loan. More down means the reverse: more cash committed up front, a smaller loan and payment, and no PMI from day one at 20%. The comparison that decides it is household-specific — the payment at each level, the insurance cost and how long it lasts, and what remains in reserve after closing. A lender can run those numbers on the same Loan Estimate form for each option; the decision deserves the arithmetic, not the folklore.
Lenders verify the down payment's source, so the money's paper trail matters as much as the amount: savings with bank statements behind them, proceeds from a home being sold, and gifts — most programs allow a family gift toward the down payment, documented with a signed gift letter stating it is not a loan. Many states and localities also run down payment assistance programs for first-time and qualifying buyers; the local lender's list is the current one. And the down payment is never the whole cash target: beside it sit closing costs (about 2% to 5% of the price as a planning range), the earnest money credited at closing, any reserves the lender requires, and the costs of moving in. The wire at the end — cash to close — is the down payment plus closing costs, minus what is already deposited or credited.
Homeowner HQ does not lend, quote down payments, or decide eligibility — the minimum that governs a purchase is the one in that buyer's program and that buyer's lender's approval, stated on the Loan Estimate. What HQ keeps straight is what the down payment becomes the day after closing: it is the buyer's opening equity, the first piece of the value-minus-owed figure the monthly update tracks from then on.
Your own agent sends a monthly value update from Homeowner HQ — the estimate, labeled as an estimate, with your equity beside it — and HQ runs on Amazon AWS. That equity line starts at the down payment and moves from there: it grows as the balance is paid down and as the home's value changes, which is why the purchase paper — the settlement statement showing the down payment, the loan amount, and the closing costs together — is worth filing against the tracked record rather than in a closing folder that gets lost. If a fact about the home changes, correct it in HQ with your own agent the same week, so the home you track stays the home on paper.
Homeowners are always free. Realtors pay $25/mo to join and lenders join at the $5/mo founding rate, at any book size, with no setup fee; sending messages inside HQ is a $100/mo unlock ($125/mo total for realtors, $105/mo total for lenders). A lender-sponsored realtor joins for $0.
Homeowner HQ is an AI-powered marketing department for agents and lenders — a relationship and revenue engine, not a homeowner database. A homeowner's record routes them back to their own agent; it is never sold and never shown to lenders.
