Frequently Asked Questions

How much should you put down on a house?
The "right" down payment depends on your financial situation, goals, and loan type. Here's a framework: the 20% benchmark: a 20% down payment is the traditional target because it: eliminates PMI (saving $100–$300/month on a $300k loan). Gives you immediate equity and better loan terms. Signals creditworthiness to lenders (often results in slightly better rates). Reduces monthly payment and total interest paid. However, 20% isn't mandatory and often isn't optimal for everyone. When to put down less than 20%: opportunity cost: if you can earn 7–10% in investments, tying up extra cash in a home (which earns the home's appreciation rate) may not be optimal. Emergency fund preservation: it's often wiser to put 5–10% down and keep 6 months of expenses in reserve than to put 20% down and deplete your emergency fund. First-time buyers in high-cost markets: waiting to save 20% on a $600k home ($120k needed) may mean years of missed home appreciation. When 20% makes sense: in a high-rate environment (higher rates make PMI less costly relative to interest, but larger loan increases monthly payment more). If you plan to stay long-term (PMI costs over time are significant). If you're risk-averse and want lower monthly obligations. If you have excellent savings discipline and the home is within comfortable reach of your income. Minimum options: conventional loans allow 3–5% down. FHA allows 3.5% down (with 580+ credit score). VA and USDA allow 0% down for eligible borrowers. Bottom line: there's no universal "right" answer. Compare: monthly payment at various down payment levels, total cost including PMI over the expected hold period, opportunity cost of cash deployed to down payment vs. investment returns.
What is PMI and how do you avoid it?
PMI (Private Mortgage Insurance) is insurance that protects your lender (not you) if you default on your mortgage. It's required on conventional loans when your down payment is less than 20% of the home's purchase price. PMI cost: typically 0.2–1.2% of your loan balance per year, depending on: credit score (higher credit = lower PMI rate). Down payment amount (closer to 20% = lower PMI rate). Loan type and lender. On a $300,000 loan with 5% down: PMI of 0.8% = $2,400/year = $200/month. PMI comes in different forms: borrower-paid PMI (BPMI): added to monthly payment — most common. Single-premium PMI: paid upfront at closing (lump sum). Lender-paid PMI (LPMI): lender pays PMI; you pay higher interest rate instead. Split premium: combination of upfront + monthly. How to remove PMI: automatic cancellation: under the Homeowners Protection Act (HPA), lenders must automatically cancel PMI when your loan balance reaches 78% of the original purchase price (based on scheduled payments). Request cancellation at 80% LTV: once your balance reaches 80% of the original value, you can request PMI removal in writing. If home value has risen, you may be able to get an appraisal to demonstrate 80% LTV sooner. Refinancing: if rates are favorable and your home value has risen, refinancing eliminates PMI on the new loan. How to avoid PMI entirely: put 20% or more down. Use an 80/10/10 piggyback loan (80% first mortgage, 10% second mortgage/HELOC, 10% down — though this is less common now). VA loan (no PMI for eligible veterans). Note: FHA loans use MIP (mortgage insurance premium) instead of PMI. FHA MIP cannot be removed on loans with <10% down made after 2013 — it lasts the life of the loan. This is a significant disadvantage of FHA vs. conventional for buyers who can afford 5–10% down.
What is the minimum down payment for a house?
The minimum down payment depends on the loan type: Conventional loans: 3% down minimum (Fannie Mae HomeReady or Freddie Mac Home Possible programs). Standard conventional: 5% minimum at most lenders. Best rates: 20% or more. FHA loans: 3.5% down minimum (with 580+ credit score). 10% down required if credit score is 500–579. VA loans: 0% down for eligible military veterans, service members, and surviving spouses. No PMI required, but a one-time funding fee applies (1.25–3.3% of loan amount, can be financed). USDA loans: 0% down for eligible rural/suburban properties. Geographic and income limits apply. A one-time guarantee fee and annual fee apply (instead of PMI). Jumbo loans (above conforming limit): typically 10–20% minimum. Higher credit score requirements. Stricter debt-to-income ratios. What the minimum actually costs: on a $300,000 home: 3% down (conventional) = $9,000 down + ~$6,000–$12,000 closing costs + reserves = $15,000–$21,000 cash needed. 3.5% down (FHA) = $10,500 down + closing costs + reserves = similar total cash needed, but with ongoing MIP. 0% down (VA) = no down payment + VA funding fee (can be financed) + closing costs. Practical minimum: the minimum down payment is only part of the cash needed. Most buyers should budget: down payment + 2–5% of purchase price for closing costs + 2–3 months of PITI (principal, interest, taxes, insurance) for reserves that some lenders require.
How much house can I afford based on down payment?
Down payment is only one factor in home affordability — but it's a critical lever. The relationship between down payment and affordability: 1. Down payment determines loan size: Home Price − Down Payment = Loan Amount. Larger down payment → smaller loan → lower monthly payment and less interest paid over time. 2. Loan size drives monthly payment: at 7% interest on a 30-year mortgage: $200k loan → $1,331/month principal + interest. $300k loan → $1,996/month. $400k loan → $2,661/month. 3. Lenders look at debt-to-income (DTI): your total monthly debt payments (mortgage + all other debts) should be below 43% of gross monthly income (some programs allow up to 50%). Your front-end DTI (just housing: mortgage + taxes + insurance + HOA) should be below 28–31%. Income needed for common loan amounts (rough, assuming 7% rate, 30-year, 1.2% property tax, 0.5% insurance): $200k loan → ~$50,000–60,000/year income recommended. $300k loan → ~$75,000–90,000/year. $400k loan → ~$100,000–120,000/year. $500k loan → ~$125,000–150,000/year. Practical approach: Start with your monthly budget: determine the maximum monthly payment you're comfortable with. Back-calculate the loan size: at 7%, $1,500/month = ~$226k loan; $2,000/month = ~$300k loan; $2,500/month = ~$376k loan. Add your down payment: max loan + your down payment = max home price. Check affordability ratios: ensure DTI is under 43% with actual income. Example: you earn $90k/year ($7,500/month). Max front-end DTI (28%) = $2,100/month for housing. At 7% with taxes and insurance, that supports roughly a $280k loan. With 10% down, you can afford roughly $310k home. With 20% down, roughly $350k home.

Key Takeaways

  • First-time buyers can put as little as 3% down with conventional loans
  • FHA loans require only 3.5% down with a 580+ credit score
  • VA and USDA loans offer 0% down payment options for eligible buyers
  • A larger down payment means lower monthly payments and less interest over time

Note: Down payment minimums are federal or lender minimums — your specific lender may require more. Higher down payment generally = lower interest rate, no PMI, lower monthly payment. The 20% down threshold is significant: it eliminates PMI, improves your debt-to-income ratio, and signals financial stability to lenders.

Note: PMI is private mortgage insurance required by lenders when you put less than 20% down on a conventional loan. It protects the lender (not you) against default. PMI is removed automatically when your loan balance reaches 78% of the original home value (Homeowners Protection Act). You can also request removal at 80% LTV if the home's value has increased. PMI rates vary by credit score, loan type, and lender. FHA loans use MIP (mortgage insurance premium), which works differently and is harder to remove.

$1,000,000$30,000$50,000$100,000$200,000
Note: These amounts are the down payment only and do not include closing costs (typically 2–5% of home price) or cash reserves that many lenders require. A $400,000 home with 10% down requires: $40,000 down + $8,000–$20,000 closing costs + 2–3 months reserves = $50,000–$65,000 total cash needed at closing.

A mortgage down payment is the upfront cash you pay toward the purchase of a home. It's expressed as a percentage of the total purchase price. For example, a 20% down payment on a $400,000 home would be $80,000.

The down payment reduces the amount you need to borrow from a lender. A larger down payment typically means:

  • Lower monthly mortgage payments
  • Better interest rates (lenders view you as less risky)
  • No PMI requirement (if 20% or more)
  • More equity in your home from day one

How Much Should You Put Down?

The "right" down payment depends on your financial situation, loan type, and goals:

Pro Tip: The 20% Sweet Spot

While 20% down isn't required, it's often the optimal target. You avoid PMI ($100-300/month savings), get better rates, and start with meaningful equity. But don't deplete your emergency fund to reach 20% - having 3-6 months of expenses saved is more important.

Understanding PMI (Private Mortgage Insurance)

PMI is insurance that protects the lender if you default on your mortgage. It's required when you put less than 20% down on a conventional loan.

Typical PMI costs: 0.5% to 1% of the loan amount per year, or about $50-100 per month for every $100,000 borrowed.

Good news: PMI isn't forever. Once you reach 20% equity (through payments or appreciation), you can request PMI removal. Lenders must automatically cancel it at 22% equity.

Down Payment Requirements by Loan Type

  • Conventional loans: 3-5% minimum (3% for first-time buyers)
  • FHA loans: 3.5% with 580+ credit score, 10% with 500-579 score
  • VA loans: 0% for eligible veterans and active military
  • USDA loans: 0% for rural property purchases
  • Jumbo loans: 10-20% typically required

How to Calculate Your Down Payment

Use this simple formula:

Down Payment = Home Price x Down Payment Percentage

Example: $350,000 home x 10% = $35,000 down payment

Don't forget to budget for closing costs (2-5% of the loan amount) in addition to your down payment!
