I bought my first house at 29, and I’ll be honest — I had no idea what I was doing. I’d been saving aggressively for a couple of years, had a good credit score, and assumed that was enough. It was not enough. I didn’t understand PMI, I underestimated closing costs, and I had no real sense of what homeownership’s ongoing costs would look like. I got lucky in a lot of ways, but I also paid some tuition in the form of mistakes I could have avoided.
If you’re working toward buying a house, here’s what I wish someone had walked me through earlier.
Start with an Honest Look at Your Finances
Before you start browsing Zillow listings, get clear on your actual financial position. Calculate your net worth — assets minus liabilities. Pull your credit report from all three bureaus (free at annualcreditreport.com) and check your score. Lenders use your credit score to determine both whether you qualify and what rate you’ll get, and the difference between a 680 and a 740 score can translate to thousands of dollars over the life of a mortgage.
If you have high-interest debt — credit cards, personal loans — pay those down before you intensify the down payment savings push. The math usually favors eliminating 20%+ APR debt before adding to a savings account earning 4-5%.
Figure Out a Real Budget
The standard rule of thumb — spend no more than 30% of gross monthly income on housing — is a starting point, not a rule. It doesn’t account for property taxes, insurance, HOA fees (if applicable), or maintenance. A house that pencils out at 30% of gross income can easily run 35-40% when you factor in all the actual costs.
Use an online mortgage calculator with the full picture: principal + interest + estimated property taxes + homeowners insurance. In most markets, property taxes alone can add $300-700/month to the payment on a median-priced home. Budget for that before you decide how much house you can afford.
The Down Payment Math
The traditional target is 20% down, and for good reason: it eliminates private mortgage insurance (PMI), which typically runs 0.5-1.5% of the loan amount annually. On a $400,000 loan, that’s $2,000-6,000 per year in PMI until you reach 20% equity. That’s real money for coverage that protects the lender, not you.
That said, 20% down isn’t always achievable or even optimal. FHA loans allow 3.5% down with a credit score as low as 580. Conventional loans let you put 3% down if you have strong credit. Some first-time buyer programs go even lower. The tradeoff is PMI and higher monthly payments, but sometimes getting in the door earlier makes financial sense depending on the market.
High-yield savings accounts and CDs are the appropriate vehicles for down payment money — not the stock market. You don’t want a market correction eating 20% of your down payment fund six months before you’re ready to buy.
Understand Your Mortgage Options
Conventional loans, FHA loans, VA loans (for veterans — genuinely excellent terms), and USDA loans (for rural areas) all have different requirements and tradeoffs. Get pre-approved at multiple lenders before you start making offers. Pre-approval isn’t just about knowing your budget — it’s a competitive signal to sellers that you’re serious and financially qualified.
Compare offers on APR, not just interest rate. APR includes fees and gives you a more accurate total cost comparison. A lender offering a slightly lower rate but higher origination fees might actually cost you more.
First-Time Homebuyer Programs
These are worth investigating before you assume you need a full 20% down. Many states have programs offering down payment assistance, reduced rates, or closing cost help for first-time buyers within certain income limits. The HUD website has a state-by-state directory. Some employers also offer homebuying assistance. It’s worth a few hours of research — these programs can translate to thousands of dollars in help.
Plan for Closing Costs
This is what surprised me most. Closing costs typically run 2-5% of the loan amount — on a $350,000 home, that’s $7,000-17,500 in addition to your down payment. These cover things like loan origination fees, appraisal, title search, title insurance, and prepaid items like homeowners insurance and property tax escrow.
Some of these costs are negotiable. Ask the seller to cover closing costs as part of the offer negotiation, especially in a buyer’s market. And shop around for title insurance and other service providers — not everything is set in stone.
The Ongoing Costs Nobody Warns You About
Budget roughly 1% of the home’s value annually for maintenance. That sounds like a lot until the HVAC dies or the roof needs replacement. On a $350,000 house, that’s $3,500/year — about $290/month you should be mentally setting aside even if you’re not literally earmarking it. Some years you’ll spend nothing; other years you’ll spend $8,000 on something unexpected.
Property taxes vary enormously by location. Homeowners insurance is usually $100-200/month. If there’s an HOA, factor in those fees. Utility bills typically go up when you own more square footage than you were renting. None of these appear on the mortgage payment, but they all affect whether homeownership is actually affordable for you.
A Few Things I’d Tell My Younger Self
Get the inspection and actually read the report — every item on it, not just the summary. A house inspection saved a friend of mine from buying a place with $40,000 in hidden foundation issues that the sellers were aware of. Don’t waive the inspection to compete in a hot market unless you’re truly prepared for any outcome.
The right home is the one you can actually afford without stress, not the nicest one you can technically qualify for. A lender will often approve you for more than you should borrow. The pre-approval letter is a ceiling, not a target.
Homeownership builds wealth — but mainly through equity accumulation and forced savings, not through the frictionless appreciation people often assume. It’s a good long-term bet, but only if the monthly costs genuinely fit your budget without crowding out retirement contributions and other financial priorities.
