How Old Do You Have to Be to Buy a House?

Buying a house is one of the biggest financial milestones you can reach but how soon can you realistically get there? If you’ve ever wondered “how old do you have to be to buy a house?”, the answer might be both simpler and more layered than you expect. 

The legal age to buy a house is generally 18 across most states, but being “ready” to buy a house has a lot more to do with your finances than your birthday. 

Whether you’re dreaming of a condo in Detroit, MI or a house in Naperville, IL, this Redfin guide breaks down the legal requirements, financial readiness, and smart strategies to help you reach your homeownership goals at any age.

How old do you have to be to buy a house?

Let’s start with the basics. In most states, you need to be at least 18 years old to legally buy a house. This is the age of majority—the legal age when you can sign binding contracts, including real estate agreements and mortgage documents. 

That said, there are a few exceptions. While 18 is the standard in most states, three states have different age requirements when it comes to buying a house:

• In Alabama and Nebraska, the age of majority is 19
• In Mississippi, the age of majority is 21.

While minors technically can own property (say, through a trust or inheritance), they can’t legally enter into a mortgage or purchase contract on their own. So unless a guardian co-signs or holds the deed in trust, you’ll have to wait until you reach your state’s age of majority.

How old are most first-time homebuyers?

So you can buy a home at 18 but do most people actually do that? Not really. According to the National Association of Realtors (NAR), the average age of first-time homebuyers is 38, and that number has been trending upward. In fact, today’s first-timers are older than ever, thanks to factors like rising home prices, student loan debt, and stricter lending standards.

Financial readiness: What really matters

Just because you’re legally allowed to buy a home doesn’t mean you’re financially ready. The biggest hurdle isn’t age—it’s affordability. Here are some key factors that determine whether you’re ready to take on a mortgage:

Buying a home is more about these numbers than your age. If you’ve built up savings, have solid credit, and can afford the monthly payments, you may be in a better position than someone older who hasn’t prepared.

While lenders can’t discriminate based on age, retirees and older adults may face challenges qualifying for a mortgage based on fixed income. That said, there’s no legal upper limit on homebuying; it’s more about your financial comfort and long-term goals.

Pros and cons of buying a house young

Buying a home in your late teens or early 20s can be an impressive achievement but it’s not without its trade-offs.

Pros:

• First-time buyer perks: Many grants and assistance programs are available.
• Long-term investment: Rising home values can benefit you down the line.
• Build equity early: The sooner you buy, the sooner your investment grows.
• Credit boost: On-time mortgage payments strengthen your credit profile.
• Stability: Owning a home has benefits like a sense of permanence and independence.

Cons:

• Homeownership expenses: Monthly costs, repairs, and taxes can stretch your budget.
• Career limitations: Owning a home can make relocation more complicated.
• Less flexibility: Renting allows for more freedom and fewer long-term ties.
• Maintenance responsibilities: You’re in charge of upkeep, not a landlord.

Home buying strategies for young buyers

Buying a house young isn’t easy but it’s definitely doable with some planning. Here are a few strategies that younger buyers are using:

• Living at home to save aggressively on rent and utilities
• Co-buying with a partner, sibling, or friend to split the down payment and monthly costs
• Moving to a more affordable city or suburb where home prices are lower
• Getting family help through a gift, co-signing, or shared equity
• Building credit early with responsible credit card use or secured loans

If you’re serious about homeownership, don’t be discouraged by the national averages. Focus on what’s right for you and look for programs or solutions that align with your situation.

Mortgage options for young homebuyers

If you’re a young buyer ready to take the leap, there are several mortgage options designed to make it easier to get started. These include:

• FHA loans: Great for first-time buyers with lower credit scores. You can qualify with as little as 3.5% down and a 580 score.
• Conventional 97: Backed by Fannie Mae or Freddie Mac, these loans offer 3% down options. Best for buyers with higher credit (typically 620 or above).
• VA loans: For eligible veterans or active-duty service members. No down payment or PMI required.
• USDA loans: Targeted for rural or low-income areas. Offers zero-down options for qualifying buyers.
• State or local first-time buyer programs: Many states and cities offer down payment assistance, reduced-interest loans, or grant money to qualified first-time buyers.

Research each program carefully; eligibility requirements, interest rates, and insurance costs can vary. A mortgage lender can help you explore which option fits your financial situation best.

FAQs: At what age can you buy a house?

1. Can a 16-year-old buy a house?

Legally, no. While a 16-year-old can inherit property or own it through a trust, they can’t sign a mortgage or purchase contract without a legal guardian.

2. What credit score does a young buyer need?

A 580 score is the bare minimum for FHA loans. For better terms, aim for 620+ for conventional loans.

3. Do student loans affect your ability to get a mortgage?

Yes, your debt-to-income ratio matters. If your student loan payments are high relative to your income, it can make qualifying for a mortgage more difficult.

4. Can you get a mortgage with no job but high savings?

It’s possible, but rare. Lenders typically want proof of steady income. Substantial savings help, but they don’t replace job income unless you have assets or a large down payment.

5. Is it smarter to rent when you’re young?

That depends. Renting can offer flexibility, especially if your job or location might change soon. However, if you plan to stay put and can afford the upfront costs, buying may be the better long-term move.
