The amount you need depends on your down payment, closing costs, and reserves

There is no single number that works for everyone. What you need to save depends on three things: how much of the purchase price you want to put down upfront, what the closing costs will be (the fees and taxes that happen at signing), and whether you want money left over after you buy. A person buying a $300,000 house with a 20% down payment faces a completely different savings target than someone buying the same house with 3% down.

The most useful way to think about it is to work backward from a specific house price in your area, then add up the pieces. That gives you a real number to save toward instead of a vague goal.

Key Takeaways

  • Down payment size varies widely—3% to 20% of the purchase price—and the percentage you choose directly determines how much you need to save.
  • Closing costs typically run 2% to 5% of the purchase price and include appraisal fees, title insurance, and loan origination fees that you pay at signing.
  • Lenders usually require you to have reserves (money left in the bank after closing) if your down payment is below 20%.
  • Your actual savings target should include down payment, closing costs, and reserves, then add a buffer for inspection repairs or appraisal gaps.

How down payment percentage changes what you save

The down payment is the money you give the seller at closing. The rest of the purchase price becomes your mortgage loan. A larger down payment means a smaller loan, lower monthly payments, and no mortgage insurance. A smaller down payment means you borrow more, pay more per month, and usually pay an extra fee called private mortgage insurance (PMI) until you own 20% of the home.

Down payments range from 3% to 20% for conventional loans, though some programs go lower. On a $300,000 house, 3% is $9,000 and 20% is $60,000. That $51,000 difference is real money you either save now or borrow and pay interest on for 30 years. Many first-time buyers choose 5% to 10% because it balances saving time against monthly payment size.

The percentage you choose is partly a financial decision (how much can you afford to borrow?) and partly a personal one (how long are you willing to save?). There is no wrong answer, only trade-offs.

Closing costs are separate from down payment

Closing costs are the fees and taxes you pay when you sign the mortgage papers. They are not part of the down payment—they are money on top of it. These costs typically run 2% to 5% of the purchase price, though the exact amount depends on your location, the loan type, and the lender.

Common closing costs include the appraisal fee (the lender's inspection of the house), title insurance (protection against ownership disputes), loan origination fees (the lender's processing cost), property taxes (paid upfront for the remainder of the year), homeowners insurance (required by the lender), and attorney fees (required in some states). On a $300,000 house, closing costs might range from $6,000 to $15,000.

Some closing costs can be negotiated or rolled into the loan, but you should plan to pay them in cash at signing. Your lender will give you a detailed estimate called a Closing Disclosure at least three days before signing, so you will know the exact amount.

Lenders require reserves if your down payment is small

If you put down less than 20%, most lenders require you to have reserves—money left in your bank account after closing. This is a safety net. It shows the lender you can cover a mortgage payment or two if you lose income, and it covers unexpected repairs that come up after you move in.

Reserve requirements vary by lender and loan type, but common amounts are one to three months of your total monthly housing payment (mortgage, property taxes, insurance, and HOA fees if any). If your housing payment is $2,000 per month and the lender requires three months of reserves, you need $6,000 sitting in the bank after you close.

This means your total savings target is not just down payment plus closing costs. It is down payment plus closing costs plus reserves. On a $300,000 house with 10% down, 3% closing costs, and three months of reserves, you might need $45,000 to $55,000 saved before you can close.

Add a buffer for inspection repairs and appraisal gaps

After you make an offer and the seller accepts, you pay for a home inspection. The inspector will find things that need repair—a roof that is aging, a furnace nearing the end of its life, foundation cracks, plumbing issues. Some are expensive. You will negotiate with the seller to fix them, lower the price, or accept them as-is. If you accept them, you need money to fix them yourself.

There is also the possibility of an appraisal gap. The lender orders an appraisal to confirm the house is worth what you agreed to pay. If the appraisal comes in lower than your offer, you have to make up the difference in cash or renegotiate. This is less common in a balanced market but happens regularly when prices are rising fast.

A practical approach is to add 5% to 10% of the purchase price to your savings target as a repair and appraisal buffer. On a $300,000 house, that is $15,000 to $30,000 extra. It sounds like a lot, but it keeps you from borrowing more or delaying the purchase because of a $5,000 roof repair.

How to calculate your specific savings target

Start with a realistic house price in your area. Look at recent sales of homes you would actually buy, not the cheapest or most expensive listings. That is your purchase price.

Multiply the purchase price by your chosen down payment percentage (3%, 5%, 10%, or 20%). That is your down payment amount.

Multiply the purchase price by 3% to 5% to estimate closing costs. Use 3% if you are in a low-cost area or using a discount lender; use 5% if you are in a high-cost area or using a full-service bank.

Estimate your monthly housing payment using an online mortgage calculator. Multiply that by the number of months of reserves your lender will require (usually one to three). That is your reserves amount.

Add down payment plus closing costs plus reserves, then add 5% to 10% of the purchase price as a buffer. That total is what you should aim to save.

Example: $300,000 house, 10% down, 3% closing costs, three months of reserves, 5% buffer.

  • Down payment: $300,000 × 0.10 = $30,000
  • Closing costs: $300,000 × 0.03 = $9,000
  • Estimated monthly payment: $2,000 (mortgage, taxes, insurance)
  • Reserves: $2,000 × 3 = $6,000
  • Buffer: $300,000 × 0.05 = $15,000
  • Total savings target: $60,000

Frequently Asked Questions

Can I borrow money for my down payment?

Most lenders do not allow borrowed down payment money because it increases your debt-to-income ratio and makes the loan riskier. Some programs (like certain first-time buyer programs) allow gifts from family, but the gift must be documented and the giver cannot expect repayment. Borrowed money from a friend or family member counts as a debt.

What if I do not have enough saved yet?

You have several options: save longer, buy a less expensive house, put down a smaller percentage (3% instead of 10%), or look into first-time buyer programs that may have lower down payment requirements or closing cost assistance. Some employers and nonprofits also offer down payment help programs.

Do I need to save the full amount before I start looking?

No. Many people start looking once they have saved 50% to 75% of their target, then finish saving while they search. This lets you understand what is actually available in your price range and adjust your target if needed. Just do not make an offer until you are confident you can close.

What happens to my savings if the appraisal comes in low?

You will need to cover the gap in cash, renegotiate the price with the seller, or walk away from the deal. If you have a buffer saved, you can cover a modest gap. If you do not, you may lose your earnest money deposit (the money you put down to show you are serious about the offer).

Are there programs that help with down payment or closing costs?

Yes. Many state and local governments, nonprofits, and some employers offer down payment assistance, closing cost help, or favorable loan terms for first-time buyers or people in specific professions. These vary widely by location. Your lender or a local housing counselor can tell you what is available where you live.
