# How Old Do You Have to Be to Buy a House? (2026) By Opendoor Editorial Team | 2026-05-18 You must be **at least 18 years old** to buy a house in most U.S. states — that's the age of majority, the age at which you can sign a legally binding contract. Three states differ: **Alabama** and **Nebraska** require age 19, and **Mississippi** requires age 21. Below the legal age, you can own property through a trust or inheritance, but you can't directly sign a mortgage or purchase contract. That's the legal minimum. The financial minimum is a different story — and it's the one that actually decides whether you can buy a house, regardless of your age. ## The Short Answer | State group | Minimum age to sign a purchase contract | | --- | --- | | 47 states + D.C. | 18 | | Alabama, Nebraska | 19 | | Mississippi | 21 | Below the legal age, you can own real estate only through a trust, a custodial arrangement (Uniform Transfers to Minors Act), or inheritance — and an adult signs the paperwork on your behalf. Even at 18, most lenders won't approve a mortgage unless you also meet the financial requirements: a qualifying credit score, two years of documented income, a manageable debt-to-income ratio, and enough cash for the down payment and closing costs. ## What "Old Enough" Actually Means There are three age-related thresholds in a home purchase, and they matter in different ways: 1. **Age of majority** (state law) — the age at which you can sign a contract. 18 in most states. 2. **Mortgage age** (lender policy) — most lenders require borrowers be at least 18 because they need a borrower who can legally sign loan documents. 3. **Maximum age** — there isn't one. The Equal Credit Opportunity Act prohibits lenders from denying mortgages based on age. A qualified 80-year-old can get a 30-year mortgage. The age of majority is the only hard floor. Below it, you can't sign — full stop. Above it, age is irrelevant; only your finances matter. ## Can a 16-Year-Old Own a House? A 16-year-old (or any minor) can own real estate, but cannot directly purchase it. The two paths: - **Trust ownership.** A parent, grandparent, or other adult establishes a trust naming the minor as beneficiary. The trustee manages the property until the minor reaches the age of majority. - **Uniform Transfers to Minors Act (UTMA) account.** Similar to a trust, an adult custodian manages property on behalf of the minor until they reach the age set by state law (typically 18 or 21). - **Inheritance.** Property left to a minor goes into a trust or is held by a guardian until the minor reaches majority. In all three cases, an adult is the legal signer for the transaction. The minor doesn't sign a mortgage and doesn't take out a loan. Direct mortgage borrowing is locked until age 18 (or 19/21 in the three exception states). ## What Lenders Actually Require — Regardless of Age Once you're at the legal minimum age, the lender's checklist starts. Here's what actually decides whether you can borrow. ### Credit score You need a credit history before lenders will approve a mortgage — and at 18 or 19, building this is the biggest practical hurdle. | Loan type | Minimum credit score | Minimum down payment | | --- | --- | --- | | Conventional | 620 | 3% | | FHA | 580 (or 500 with 10% down) | 3.5% | | VA | 580–620 (lender-dependent) | 0% | | USDA | 640 | 0% | To build credit before applying, open a credit card at 18, make small charges, and pay the balance in full each month. After 12–18 months you'll typically have enough credit history for lender review. For a full breakdown of how credit scores affect approval and pricing, see: [What Credit Score Do You Need to Buy a House?](/articles/credit-score-to-buy-a-house) ### Income and employment history Lenders typically want **two years of stable, documented income**. Recent grads can sometimes substitute degree completion for the 2-year history — especially if you're working in your field of study. Self-employed income takes longer to document. ### Down payment Young buyers often have the smallest down payments. The good news: FHA loans take 3.5% down, and VA/USDA loans allow 0%. | Loan type | Accepted by Opendoor? | Minimum down payment | Notes | | --- | --- | --- | --- | | Conventional | Yes | 3% | Credit 620+; PMI required under 20% down | | FHA | Yes | 3.5% | Credit 580+; MIP required; 90-day flip rule applies | | VA | Yes | 0% | Eligible service members and veterans | | USDA | Yes | 0% | Rural and qualifying low-income areas | | Cash | Yes | N/A | Can close in as few as 14 days | If you have no down payment saved, see: [How to Buy a House with No Money Down](/articles/how-to-buy-a-house-with-no-money-down). ### Debt-to-income ratio Most lenders cap your total debt payments (including the new mortgage) at 43% of gross monthly income. Student loans are the most common DTI drag for young buyers — payments push the ratio up and reduce how much mortgage you qualify for. ## The Reality: Most People Don't Buy at 18 The average age of a first-time home buyer in the U.S. is now **38 years old**, according to NAR data — and that average has crept up steadily as down payment requirements, prices, and student debt have grown. Most "young buyers" buy in their late 20s or early 30s, not in their late teens. That's not a rule. It's a reflection of how long most people need to save a down payment, build credit, and stabilize their income. If you're 18 to 22 and ready to buy, you're early — but not unreasonably so. Most of what holds young buyers back is cash, not age. ## Strategies for Young Buyers If you're 18–25 and want to buy as soon as possible: - **Start credit at 18.** Get a single credit card, charge small monthly amounts, pay in full. You'll have a usable credit history by 19 or 20. - **Live below your means.** Renting with roommates, staying with family longer, or moving to a cheaper market while you save is the fastest path to a down payment. - **Co-buy with a partner or family member.** Two incomes change the math. A parent co-signer or co-borrower can also dramatically boost what you qualify for. - **Use first-time buyer programs.** Many states and cities offer down payment assistance grants or low-interest loans for first-time buyers under specific income thresholds. Search "\[your state\] first-time home buyer programs." - **Buy where prices are reasonable.** A $200,000 home in a Midwest city is achievable on a young buyer's income; a $700,000 home in a coastal market usually isn't. See: [Cheapest States to Buy a House](/articles/cheapest-states-to-buy-a-house). - **Consider FHA.** Lower down payment (3.5%), lower credit minimum (580), more lenient DTI. Built for buyers who don't yet have decades of credit history or large savings. For loan-type comparisons, see: [Types of Mortgage Loans](/articles/types-of-mortgage-loans). ## Can a Parent Co-Sign or Help? Yes — and it's one of the most common ways young buyers qualify. Three structures: - **Co-borrower.** The parent is on the loan and on the title. Their income and credit count toward qualification. They share legal responsibility for the loan and the property. - **Co-signer.** The parent signs the loan and guarantees repayment but isn't on the title. Their credit is on the hook if you default. - **Gift letter.** The parent gives down payment money outright (no repayment). Most lenders require a signed gift letter stating the funds aren't a loan. Each has tax and legal implications — particularly for the parent's debt-to-income capacity and any future property they want to buy. Worth a conversation with a tax advisor before structuring it. ## Is Buying Young Actually Smart? There's a real debate here. The case for buying young: - **You build equity instead of paying rent.** A 22-year-old who buys and stays 10 years has roughly 25% of their loan paid down, plus appreciation. - **You start building credit history early.** Mortgage payments are some of the most positive credit data. - **You access tax advantages.** Mortgage interest deductions, plus the capital gains exclusion ($250k single / $500k married) if you stay 2+ years. The case for waiting: - **You lose flexibility.** Career moves and relocations are harder when you own. Transaction costs (8–10% of the home value) make selling within 3 years usually a financial loss. - **You over-extend.** Buying at the limit of what you qualify for, with a thin emergency fund, is the most common young-buyer mistake. One job loss or major repair can blow up the plan. - **You buy the wrong home.** What you need at 22 and what you'll need at 27 may differ a lot.
