First-Time Home Buyer Guide: Every Step, In Order
Buying a first home involves roughly a dozen decisions, most of which are made once and then live with you for thirty years. The order matters as much as the choices, because several of them close off options later.
This guide walks the sequence in the order it actually happens, and flags the points where first-time buyers most commonly lose money.
Key takeaways
- Budget from the full PITI payment, not the principal-and-interest quote — the gap is usually 25–40%.
- Closing costs of 2–5% are separate from the down payment and due at closing.
- A 740+ credit score typically unlocks the best available pricing; the gap from 680 is worth tens of thousands.
- Get pre-approved, not pre-qualified — sellers treat them very differently.
- Keep your emergency fund intact. A down payment that empties savings turns a home into a liability.
Step 1: Work out what you can afford before talking to anyone
Start with your own budget rather than a lender's approval. A lender evaluates whether you will repay the loan, which is a much narrower question than whether the purchase leaves you able to fund retirement, absorb a job loss and replace a roof.
The standard heuristic is the 28/36 rule — housing under 28% of gross income, all debt under 36%. It is a useful ceiling and a poor target. Holding housing nearer 22% of gross income leaves room for the costs the rule ignores entirely: childcare, commuting, retirement contributions and maintenance.
- Model the full PITI payment, not the advertised principal and interest
- Budget 1% of home value annually for maintenance, more on older properties
- Keep contributing to retirement — pausing it to afford a house is a warning sign
Step 2: Fix your credit 60 days out
The pricing difference between a 680 and a 760 credit score is commonly 0.4–0.6 percentage points on a mortgage rate, which on a $400,000 loan is well over $100 a month and tens of thousands across the term.
Utilization is the fastest lever — it recalculates every time your issuers report, so paying card balances down before the statement closes can move your score within a single cycle. Do not open new accounts, finance furniture, or close old cards during this window; all three work against you at exactly the wrong moment.
Step 3: Get pre-approved, not pre-qualified
Pre-qualification is an informal estimate based on information you provide without verification. It carries almost no weight with sellers. Pre-approval involves verified income, assets and a credit pull, and produces a letter that agents and sellers treat as real.
Apply to at least three lenders. Rate shopping within a 45-day window counts as a single credit inquiry, so there is no score penalty for comparing. The Consumer Financial Protection Bureau has found meaningful savings for borrowers who compare, and the spread between lenders on identical borrowers frequently exceeds half a percentage point.
Step 4: Understand what closing actually costs
Closing costs run 2–5% of the purchase price and are separate from the down payment. On a $400,000 home that is $8,000–20,000, due at closing. They cover loan origination, appraisal, title insurance, recording fees, and prepaid escrow for taxes and insurance.
The Loan Estimate you receive within three days of applying is standardized specifically so you can compare lenders line by line. Origination charges and discount points are negotiable; third-party fees such as recording and transfer taxes are not.
- Loan origination — negotiable, varies substantially between lenders
- Appraisal — $400–800, ordered by the lender
- Title insurance — protects against ownership claims; shop for it in most states
- Prepaid escrow — several months of taxes and insurance collected upfront
Step 5: Do not skip the inspection
A general inspection costs $400–700 and is the cheapest insurance in the transaction. In competitive markets buyers are sometimes pressured to waive it; doing so transfers every unknown defect onto you at the moment you have the least cash.
If waiving is genuinely unavoidable to win the offer, at minimum arrange a pre-offer walkthrough with an inspector. Foundation, roof, electrical panel, HVAC age and sewer line are where the expensive surprises concentrate — a sewer scope in particular costs around $200 and regularly finds five-figure problems.
Common questions
How much do I need for a down payment?
Conventional loans allow as little as 3% for qualified first-time buyers, FHA loans 3.5%, and VA and USDA loans nothing at all for eligible borrowers. Twenty percent avoids PMI and improves pricing, but waiting years to reach it while prices and rents rise frequently costs more than the PMI would have.
What credit score do I need to buy a house?
Conventional loans generally start at 620, FHA at 580 with 3.5% down, and VA has no formal minimum though most lenders want 620. Best pricing typically begins around 740 and improves again near 780. The score to qualify and the score to aim for are very different numbers.
How long does the process take?
Typically 30–45 days from accepted offer to closing, assuming financing is in order. Add several months on the front for house hunting. Cash offers close faster, which is a meaningful part of why they win competitive situations.
Should I use a buyer's agent?
For a first purchase, generally yes. An experienced agent catches contract issues, knows which inspectors and lenders perform, and manages a timeline with real deadlines. Since the 2024 commission changes, buyer agent compensation is negotiated directly and explicitly, so ask what you are paying for and what it includes.
