The real starting point: down payment plus closing costs plus reserves

You need three separate pools of money before you can buy a house: a down payment (what you give the lender upfront), closing costs (fees paid at the end of the purchase), and cash reserves (money left over after you buy, for emergencies and repairs). Most first-time buyers underestimate the second and third, which is why they run out of money before closing day.

The down payment is the piece everyone talks about. It ranges from 3% to 20% of the home's purchase price, depending on the loan type. A house that costs $300,000 with a 5% down payment means $15,000 down. But closing costs typically run 2% to 5% of the purchase price on top of that—another $6,000 to $15,000 on the same house. Then you need reserves: lenders want to see that you can cover your mortgage payment for two to six months if your income stops, plus money for repairs a new house will inevitably need.

The total you need depends on the house price, the loan type, and where you live. There is no single number that works everywhere.

Key Takeaways

  • Down payment, closing costs, and cash reserves are three separate expenses—most buyers save for the down payment and run short on the other two.
  • Down payments range from 3% to 20% of the home price depending on loan type; closing costs add another 2% to 5% on top of that.
  • Lenders require you to have cash reserves after closing, usually enough to cover two to six months of mortgage payments plus property taxes and insurance.
  • The total amount you need varies by location, home price, and loan program—a mortgage lender can give you a specific number once you know which house you want.

Down payment: what it is and why it matters

The down payment is the money you hand over on the day you close the sale. It reduces the amount you have to borrow. A larger down payment means a smaller loan, lower monthly payments, and no mortgage insurance (the fee lenders charge when you put down less than 20%).

The minimum down payment depends on the loan program. Conventional loans (the most common type, sold to investors after closing) typically require 3% to 5% down, though some lenders go as low as 3%. FHA loans (backed by the Federal Housing Administration) allow 3.5% down. VA loans (for military members and veterans) and USDA loans (for rural properties) can allow 0% down, meaning no down payment at all. State and local first-time buyer programs sometimes offer down payment help, though the rules vary by location.

If you put down less than 20%, you will pay mortgage insurance—a monthly fee added to your mortgage payment that protects the lender if you stop paying. On a $300,000 house with 5% down, mortgage insurance might add $150 to $300 per month. That cost disappears once you build enough equity (usually when you have paid down the loan to 80% of the home's value), but it is real money you pay while you own the house.

Closing costs: the fees you pay at the end

Closing costs are the fees charged by the lender, the title company, the appraiser, the inspector, and other parties involved in the sale. They are due at closing—the day you sign the final paperwork and get the keys. Most buyers are shocked by how much these add up to.

Closing costs typically run 2% to 5% of the purchase price. On a $300,000 house, that is $6,000 to $15,000. The exact amount depends on the loan type, the lender, your location, and what the seller agrees to pay. Some of the largest fees are the loan origination fee (what the lender charges to process the loan), the appraisal fee (to verify the house is worth what you are paying), title insurance (to protect you if someone else claims ownership), and property taxes and homeowners insurance (prepaid at closing for the first few months).

You will receive a Closing Disclosure document at least three business days before closing. This lists every fee and tells you the exact amount due. Before that, you get a Loan Estimate within three days of applying for the mortgage—this is an early estimate, not the final number, but it gives you a ballpark figure to plan around.

Cash reserves: the money you keep after buying

Lenders require you to have money left in the bank after closing. This is called a cash reserve or liquid assets. The amount varies by lender and loan type, but most want to see two to six months of mortgage payments (including property taxes, homeowners insurance, and mortgage insurance if you have it) sitting in an account you can access.

The reason is practical: if you lose your job or face an emergency, you need to be able to pay your mortgage while you find new work. A lender does not want to foreclose on a house because the owner had no emergency fund. On a $300,000 house with a $1,500 monthly payment, two months of reserves means $3,000 in the bank after closing.

Some loan programs are stricter than others. Conventional loans often require two months of reserves. FHA loans may require none, though some lenders add their own requirement. VA and USDA loans typically have no reserve requirement. Ask your lender what they require before you finalize your savings goal.

How to calculate your total savings target

Start with the house price you are looking at. If you do not have a specific house yet, use a realistic estimate for your area—talk to a real estate agent or look at recent sales in neighborhoods you like.

Then add three numbers together:

  1. Down payment: Multiply the house price by your down payment percentage (3%, 5%, 10%, 20%, or whatever you are targeting). A $300,000 house with 5% down = $15,000.
  2. Closing costs: Multiply the house price by 3% to 5% as a conservative estimate. A $300,000 house × 4% = $12,000. Ask your lender for a more precise estimate once you apply.
  3. Cash reserves: Calculate your expected monthly mortgage payment (your lender can estimate this), multiply by the number of months required (usually two to six), and add that amount. On a $1,500 monthly payment with a two-month requirement = $3,000.

For the $300,000 house example: $15,000 (down payment) + $12,000 (closing costs) + $3,000 (reserves) = $30,000 total. That is 10% of the purchase price, which is a useful rule of thumb—plan to save roughly 10% of the house price you are targeting.

This is an estimate. The actual number will shift once you find a house, get a mortgage pre-approval, and receive your Loan Estimate. But it gives you a concrete savings goal to work toward.

Where the money comes from and what counts

Lenders want to see that the down payment and closing costs come from your own savings or a gift. They do not want you to borrow the down payment—that would mean you are financing 100% of the purchase, which is much riskier for them.

Money that counts toward your down payment includes savings in your bank account, money in a retirement account (some programs let you withdraw from a 401(k) or IRA without penalty for a first-time home purchase), gifts from family members, and proceeds from selling assets you own. Some first-time buyer programs provide down payment grants or forgivable loans—money you do not have to pay back, or only pay back if you sell the house within a certain time.

Lenders will ask you to document where the money came from. If you received a gift, the person who gave it must sign a gift letter stating it is a gift, not a loan. If you withdrew from retirement savings, you will need documentation of that withdrawal. Lenders do this to make sure you are not borrowing money in secret, which would increase your debt and make you a riskier borrower.

Cash reserves can come from the same sources—savings, gifts, or assets you sell. Some lenders will count retirement accounts toward reserves, though the rules vary.

How long it takes to save and what helps you get there faster

The time it takes depends on how much you need to save and how much you can set aside each month. If you need $30,000 and can save $500 per month, you are looking at five years. If you can save $1,000 per month, you could reach that goal in two and a half years.

Several things can speed up the process. A higher income means you can save more each month. A bonus, tax refund, or inheritance can jump you forward in a single month. Cutting expenses—eating out less, canceling subscriptions you do not use, refinancing debt at a lower rate—frees up money to redirect toward your down payment. A side job or freelance work adds income without changing your main job.

First-time buyer programs in your state or city may offer down payment help, closing cost assistance, or favorable loan terms. These vary widely—some states have robust programs, others have very little. Your local housing authority or a nonprofit housing counselor can tell you what is available where you live. These programs often have income limits and other rules, so you would need to learn the specifics for your area.

What happens if you do not have enough saved yet

If you are short on down payment money, you have options. You can wait and save more. You can look for a less expensive house. You can ask family for a gift. You can explore first-time buyer programs in your area. You can consider a lower down payment (3% instead of 10%) if you are comfortable with mortgage insurance. You can look into an FHA loan, which allows 3.5% down and is designed for buyers with smaller down payments.

If you are short on closing costs, some sellers will agree to pay part of your closing costs as part of the sale negotiation. This is called a seller concession. There are limits—lenders cap how much a seller can contribute—but it is worth asking your real estate agent about.

If you do not have cash reserves after closing, some lenders will allow you to close without them if you meet other strong criteria (high credit score, low debt, stable income). But this is riskier for you—you would have no cushion if something goes wrong. Most lenders will not do this.

Frequently Asked Questions

Can I use my 401(k) to pay for a down payment?

Yes, if you are a first-time homebuyer. You can withdraw up to $35,000 from a 401(k) without the usual 10% early withdrawal penalty. You will still owe income tax on the amount withdrawn. An IRA allows you to withdraw up to $10,000 lifetime for a first-time home purchase, also without the penalty. Talk to your plan administrator about the process—it takes a few weeks.

What if I get a gift from family for the down payment?

The lender will require a gift letter signed by the person who gave you the money, stating the amount and that it is a gift, not a loan you have to repay. You will also need to show bank statements proving the money arrived in your account. The gift can come from a spouse, parent, grandparent, or other family member, but not from the seller or real estate agent.

Do I have to put 20% down to avoid mortgage insurance?

Yes, 20% is the threshold where mortgage insurance goes away on a conventional loan. Below 20%, you pay mortgage insurance as part of your monthly payment. FHA loans require mortgage insurance even with a larger down payment. If you cannot save 20%, a smaller down payment with mortgage insurance is still a valid path—you just pay more per month.

What if closing costs are higher than I expected?

You can negotiate with the seller to cover some closing costs, ask the lender if they can reduce their fees, or shop around with other lenders—different lenders charge different amounts. You can also delay closing until you have saved more, though this means renegotiating the sale timeline with the seller. Get your Loan Estimate early so you have time to plan.

How much should I have in reserves after I close?

Most lenders require two to six months of your total monthly housing payment (mortgage, property taxes, insurance, and mortgage insurance if applicable). Ask your lender what they require before you close. After closing, it is wise to keep that money in the bank for emergencies—a new roof, a furnace repair, or a job loss—rather than spending it.
