A $350,000 home can look very different depending on the down payment you bring to closing. Putting down 20% means $70,000 upfront. Putting down 3% means $10,500. Both may be possible, but they create different monthly payments, mortgage insurance requirements, cash reserves, and options after you get the keys.

A down payment is the portion of the home’s purchase price you pay upfront rather than finance with a mortgage. It is one of the first numbers buyers focus on, but it should never be viewed by itself. The right amount depends on your loan program, credit profile, purchase price, available savings, closing costs, and how much financial breathing room you want after moving day.

What a Down Payment Does for Your Mortgage

Your down payment reduces the amount you borrow. If you buy a $300,000 home and put down $30,000, your mortgage starts at $270,000 before any financed fees. A larger down payment generally lowers your principal and interest payment because you are financing less.

It can also affect your loan-to-value ratio, commonly called LTV. This is the percentage of the home’s value that is financed. A buyer putting 10% down has a 90% LTV. A buyer putting 20% down has an 80% LTV. Lenders use this ratio to evaluate risk, determine mortgage insurance requirements, and in some cases price the interest rate.

More money down can strengthen an offer, particularly when a seller has several comparable offers to review. Sellers often see a larger down payment as a sign that a buyer is financially prepared. Still, a larger down payment is not automatically the best move. A buyer who uses every dollar in savings to reach 20% may be in a more vulnerable position than one who puts down less and keeps a healthy emergency fund.

Is 20% Down Required?

No. The idea that every buyer needs 20% down is one of the most persistent homebuying myths. Twenty percent can be beneficial, especially because it may eliminate private mortgage insurance on a conventional loan, but it is not a universal requirement.

Many qualified buyers purchase with less. Conventional loans may allow as little as 3% down for eligible borrowers. FHA loans often allow a 3.5% down payment for borrowers who meet credit requirements. Eligible VA borrowers may be able to purchase with no down payment, while USDA loans can offer zero-down financing for qualified buyers purchasing in eligible rural and suburban areas.

The best program is not always the one with the smallest upfront requirement. FHA financing may be a helpful route for a buyer with limited savings or a developing credit history, but its mortgage insurance structure should be reviewed carefully. A low-down-payment conventional loan may be more attractive for another buyer, especially if their credit profile supports competitive pricing. VA financing is one of the strongest benefits available to eligible service members, veterans, and surviving spouses, though borrowers should understand the potential VA funding fee and their full payment picture.

How Much Should You Put Down?

Start with your financial comfort level, not a rule of thumb from someone else’s purchase. A sensible down payment leaves room for closing costs, moving expenses, immediate repairs, furnishings, and unexpected life events.

For many buyers, the decision comes down to balancing a lower payment against keeping cash available. Putting more down reduces the amount borrowed and may lower or remove mortgage insurance. Putting less down allows you to preserve savings, buy sooner, or avoid delaying a purchase while home prices and rents continue to change.

Here are a few questions worth discussing before choosing a number:

• How much cash will remain after the down payment and closing costs?
• Will a larger down payment remove mortgage insurance or materially improve your loan terms?
• Are you likely to need funds for repairs, an appraisal gap, or a move?
• Does your chosen loan program have minimum down payment or reserve requirements?
• Are you buying a primary residence, second home, or investment property?

For a primary residence, a buyer may reasonably choose 3%, 5%, 10%, or 20% down depending on the full scenario. For second homes, investment properties, high-balance loans, and jumbo financing, required down payments can be higher. There is no one-size-fits-all percentage because the loan structure matters as much as the purchase price.

Do Not Forget Closing Costs

A down payment is separate from closing costs. Closing costs can include lender fees, title services, appraisal fees, prepaid homeowners insurance, prepaid interest, and funds collected to establish an escrow account for taxes and insurance. The exact amount varies by loan, home price, location, and transaction details.

In Texas, property taxes and homeowners insurance can significantly influence the monthly payment and the cash needed at closing. Buyers should ask for a detailed loan estimate early in the process so they can see the difference between their down payment, closing costs, prepaid items, and total funds needed to close.

In some transactions, seller concessions may help cover eligible closing costs. That can preserve more of your cash for the down payment or post-closing reserves. Concessions are subject to loan program limits and negotiation, so they should be structured carefully rather than assumed.

Where Can a Down Payment Come From?

Most buyers use savings, but that is not the only acceptable source. Depending on the loan program and your circumstances, a down payment may come from proceeds from the sale of another home, a gift from an eligible family member, certain assistance programs, or other documented assets.

The key word is documented. Mortgage lenders are required to verify where funds came from. Large unexplained deposits can slow down underwriting because the lender must confirm they are not borrowed funds or income that has not been properly sourced. If a family member plans to provide a gift, discuss it with your loan advisor before money changes hands. A simple paper trail from the beginning can prevent last-minute questions.

Down payment assistance can also be valuable for eligible first-time buyers and households meeting program requirements. These programs may offer grants, forgivable loans, or deferred-payment second liens. They can make homeownership more accessible, but they are not all alike. Some have income limits, purchase price limits, homebuyer education requirements, geographic restrictions, or repayment conditions when you sell or refinance.

Mortgage Insurance: The Trade-Off for Putting Less Down

With a conventional loan, putting less than 20% down usually means private mortgage insurance, or PMI. PMI protects the lender, not the homeowner, but it can help borrowers qualify with a smaller down payment. The cost varies based on credit score, LTV, loan type, and other factors.

The good news is that conventional PMI is often removable once you meet the loan’s equity and payment-history requirements. FHA mortgage insurance works differently and may remain for the life of the loan when the initial down payment is below 10%. That does not make FHA a poor choice. It simply means you should compare the short-term affordability and long-term cost before deciding.

A smaller down payment with mortgage insurance may still be the right answer if it allows you to purchase while keeping savings intact. On the other hand, if an additional 5% down substantially lowers PMI and leaves you with adequate reserves, it may be worth considering. The numbers should guide the decision, not pressure to hit a particular percentage.

Build Your Budget Around the Full Monthly Payment

A down payment changes your mortgage amount, but it is only one part of home affordability. Your estimated monthly housing payment may include principal, interest, property taxes, homeowners insurance, mortgage insurance, and any homeowners association dues.

This is especially relevant in markets around San Antonio, New Braunfels, Bulverde, and Austin, where tax rates, insurance premiums, and neighborhood HOA fees can vary meaningfully from one property to the next. Two homes with the same price can have noticeably different monthly costs.

Before making an offer, compare payment scenarios at several down payment amounts. For example, look at 3%, 5%, 10%, and 20% down if those options are available to you. Then compare the cash needed at closing, monthly payment, mortgage insurance, and savings left after closing. That exercise often makes the best path clearer.

A Strong Offer Starts With a Clear Plan

A pre-qualification or pre-approval helps you understand what you can comfortably afford before you fall in love with a home. It also gives you time to review loan programs, document funds, and identify whether a gift, assistance program, or different loan structure could improve your position.

The goal is not to put down the largest possible amount. The goal is to make a confident purchase with a payment that fits your life and enough cash left to enjoy your new home. A personalized conversation with a mortgage advisor can turn a broad down payment question into a practical plan built around your budget, timeline, and homeownership goals.
