First-time buyer

Your first home: Where to start

What nobody tells you before you start the process — and how to avoid common mistakes.

Buying your first home is one of the biggest financial decisions of your life — and most people go into it completely blind. This guide breaks it down into the steps that actually matter, in the order they actually happen.

Step 1 — Know your numbers before anything else

Before you look at a single house, you need three numbers: your credit score, your debt-to-income ratio (DTI), and how much cash you have saved. These three things determine what you can borrow, what rate you'll get, and whether a lender will approve you at all. You can check your credit for free at annualcreditreport.com. For DTI and savings, be honest with yourself — lenders will verify everything.

Step 2 — Get pre-approved, not just pre-qualified

Pre-approval is a real underwriting review. The lender pulls your credit, verifies your income, and tells you exactly what you can borrow. Pre-qualification is just a rough guess based on what you tell them — sellers don't take it seriously. In competitive markets, you need a pre-approval letter before making any offer.

Step 3 — Understand what you're actually paying monthly

Your monthly payment isn't just principal and interest. It includes property taxes, homeowners insurance, and PMI if you put less than 20% down. On a $350,000 home with 10% down, your all-in payment could easily be $500–$800 more per month than your P&I alone. Budget for the real number.

Step 4 — Shop at least 3 lenders

Most first-time buyers go with the first lender they talk to. That's a mistake. Even a 0.25% rate difference (say, 6.5% vs. 6.75%) on a $350,000 loan is about $20,800 over 30 years. Getting quotes from 3–5 lenders within a 45-day window counts as a single hard inquiry on your credit — it won't hurt your score to shop around.

Step 5 — Read your Loan Estimate carefully

Every lender is required to give you a Loan Estimate within 3 days of your application. This 3-page document shows your rate, monthly payment, closing costs, and every fee the lender charges. Upload it to Lighthouse Logic and we'll read every number and flag anything you should question before moving forward.

First-time buyer programs: Many states and counties offer down payment assistance, closing cost grants, and below-market rate programs. Ask your lender what's available in your area — you might qualify for more help than you think.

Step 6 — Don't make big financial moves mid-process

Once you're under contract, do not change jobs, open new credit accounts, make large purchases, or move large sums of money without telling your loan officer. Any of these can delay or kill your loan — sometimes days before closing.

Step 7 — Review your Closing Disclosure before you sign

You'll receive a Closing Disclosure 3 business days before closing. Compare it line by line to your Loan Estimate. If anything changed significantly, demand an explanation. You have the right to understand every dollar you're paying.

First-time buyer programs, requirements, and incentives vary by state, county, and lender. Speak with a licensed loan officer in your area for advice specific to your situation.
