01 Step 1: Check and Improve Your Credit Score
Pull your credit reports before you talk to a single lender, not after. Lenders use your middle score across the three bureaus, or the lower middle score if you're applying with a co-borrower, so knowing all three matters more than knowing just one.
Most conventional programs want a FICO score of 740 or higher to unlock the best pricing tier, though approval is possible well below that line. Utilization is the fastest thing to fix: keep card balances under 30% of your limit, closer to 10% if you have time, and time the payment before the statement closes rather than before it's due. Our credit score resource center goes deeper into which fixes move the needle fastest for buyers on a 60 to 90 day timeline.
Avoid opening new credit accounts once you start this process. A new auto loan or store card can drop your score right when you need it stable, and it adds a monthly payment that raises your debt load at the exact moment a lender is calculating it.
02 Step 2: Get Pre-Approved (Not Just Pre-Qualified)
These two terms get used interchangeably, and that's where buyers lose time. Pre-qualification is a quick estimate built on numbers you report yourself, no documents required, sometimes done over a single phone call. It tells you roughly what you might afford, nothing more.
Pre-approval is a different level of commitment. A lender pulls your credit, verifies income through pay stubs and W-2s, checks bank statements, and issues a conditional letter stating an actual loan amount and rate. That letter is what real estate agents ask for before showing homes in a competitive market, and it's what sellers expect attached to a serious offer.
The difference plays out at the negotiating table. A pre-qualification letter signals interest. A pre-approval letter signals that a lender has already checked your ability to close. Getting one typically takes 7 to 10 business days once you've submitted documentation, so start this step before you've found the house, not after.
03 Step 3: Choose the Right Mortgage Type
Four structures dominate the market, and each fits a different financial situation. A fixed-rate loan locks the interest rate for the entire term, which makes budgeting simple and protects against rate spikes. An adjustable-rate mortgage starts lower but resets periodically, which works for buyers planning to sell or refinance before the adjustment period hits.
Interest-only loans let you pay just the interest for a set window, keeping the initial payment low, though the balance never shrinks during that period. Negative amortization structures go a step further, allowing payments so low that unpaid interest gets added back onto the loan balance, which is why they carry real long-term risk if home values don't rise. Our breakdown at how to choose a monthly payment walks through how each one affects your payment five and ten years out.
Loan program adds another layer on top of rate structure. FHA loans accept scores as low as 580 with 3.5% down, useful for buyers still rebuilding credit. Conventional loans generally require 620 and reward higher scores with meaningfully lower mortgage insurance costs, which matters over a 30-year hold.
04 Step 4: Navigate Closing Without Surprises
Closing costs run 2% to 5% of the purchase price on top of your down payment, according to the Consumer Financial Protection Bureau. On a $350,000 home, that's $7,000 to $17,500 in cash you need beyond what you're putting down, and it catches a surprising number of first-time buyers off guard.
Three categories eat most of that budget:
- lender fees, covering origination, underwriting, and processing charges tied to issuing the loan;
- title insurance and settlement services, which protect against ownership disputes and pay the closing agent;
- prepaid items, including property tax escrow, homeowners insurance, and several months of interest paid in advance.
Escrow deserves its own explanation because it confuses almost everyone the first time. A lender collects a portion of your annual property tax and insurance bill each month, holds it in a separate account, then pays those bills on your behalf when they come due. It's not an extra cost so much as a forced savings account for expenses you'd owe regardless.
You'll receive a Closing Disclosure at least three business days before signing. Compare it line by line against your original Loan Estimate, since fees can shift between application and closing, and a lender is required to explain any increase beyond what regulations allow. Bring a cashier's check or wire the funds as instructed, show up with photo ID, and expect the paperwork itself to take one to two hours to sign.
Budget a little past the number on the Closing Disclosure too. A final walkthrough sometimes turns up a repair the seller agreed to but hasn't finished, and moving costs, a locksmith, or an HOA transfer fee rarely make it onto anyone's spreadsheet until the week of the move. None of these run more than a few hundred dollars each, but stacked together they can catch a buyer who budgeted down to the last dollar.
