The 20% down payment is a widely repeated number that doesn’t reflect how most homes are actually purchased. While 20% avoids private mortgage insurance and offers certain advantages, many loan programs allow significantly less — with tradeoffs worth understanding before deciding on your down payment target.
Why 20% Became the Standard Reference Point
At 20% down, lenders don’t require private mortgage insurance (PMI) — an additional monthly cost that protects the lender if you default. Lenders also view 20% down as lower risk, which can result in slightly better interest rate offers. On a $350,000 home, 20% down means $70,000 upfront — a barrier that delays homeownership for many buyers.
Common Low Down Payment Options
Conventional Loans (3%–5% down)
Conventional loans backed by Fannie Mae and Freddie Mac allow down payments as low as 3% for first-time buyers (defined as anyone who hasn’t owned a home in the past three years). Standard conventional loans require 5% for repeat buyers. PMI is required until you reach 20% equity, at which point you can request cancellation.
FHA Loans (3.5% down)
FHA loans, insured by the Federal Housing Administration, allow 3.5% down with a credit score of 580 or higher (10% down for scores of 500–579). FHA mortgage insurance premiums (MIP) work differently from conventional PMI — upfront MIP is 1.75% of the loan amount (often rolled into the loan), plus annual premiums based on loan term and LTV. For most FHA loans, MIP remains for the life of the loan unless you put down 10%+ (in which case it drops at 11 years).
VA Loans (0% down)
Available to eligible military service members, veterans, and surviving spouses. No down payment required, no PMI, and competitive interest rates. A VA funding fee applies (typically 1.4%–3.6% of the loan amount, depending on down payment and first-time vs. subsequent use) but can be rolled into the loan. Often the best option available to those who qualify.
USDA Loans (0% down)
Available for homes in eligible rural and suburban areas with income limits. No down payment required, but an upfront guarantee fee (1% of loan amount) and annual fee (0.35% of outstanding balance) apply. Property location and income must meet USDA eligibility requirements.
The PMI Calculation
PMI on conventional loans typically costs 0.5%–1.5% of the loan amount annually, depending on your credit score, down payment, and lender. On a $300,000 loan at 1% PMI: $3,000/year or $250/month. This continues until you reach 20% equity through payments and/or appreciation, at which point you can request cancellation (or it automatically cancels at 22% equity by law).
When calculating whether to wait for 20% vs. buy sooner with PMI, factor in the months of rent paid while saving the additional down payment, any home price appreciation during that period, and the actual PMI cost until you’d reach 20% equity.
Down Payment Assistance Programs
Many states, counties, and cities offer down payment assistance for qualified first-time buyers — often as low-interest loans, deferred loans (no payment until you sell or refinance), or outright grants. Eligibility requirements vary by income, property price, and location. HUD’s website maintains a database of state and local assistance programs.
Closing Costs Beyond the Down Payment
Down payment is not the only upfront cost. Closing costs typically run 2–5% of the loan amount: origination fees, appraisal, title insurance, prepaid interest, homeowners insurance, and property tax escrow. On a $300,000 loan, budget $6,000–$15,000 in closing costs in addition to the down payment.
Some lenders offer “no-closing-cost” mortgages where closing costs are rolled into a slightly higher interest rate. This is sometimes worthwhile for buyers who don’t have cash reserves beyond the down payment.
Keeping Cash Reserves After Closing
Spending every available dollar on a maximum down payment can leave you without a financial cushion for post-closing expenses: immediate repairs, moving costs, utility deposits, new furniture, landscaping. Many financial advisors suggest keeping 1–3% of the home’s value in liquid reserves after closing, independent of your emergency fund.
The right down payment balances reducing PMI costs and improving loan terms against preserving cash for emergencies and the inevitable post-purchase expenses. More down is not always better if it depletes reserves you’ll need in the first year of ownership.
