Every first-time-buyer decision, in the right order.

Before you start shopping, get two things right: what you can afford and what your credit looks like. These are the inputs every subsequent decision uses. Walking into pre-approval with surprises here is how borrowers end up at higher rates than they should be paying.

Run the affordability math first. The Affordability + Risk calculator returns three honest price tiers based on your income, debts, and reserves — Conservative, Comfortable, and Stretch. Lenders will approve you for Stretch (or above); your target should usually be Conservative or Comfortable. The gap matters enormously.

Then check your credit. Pull free reports from AnnualCreditReport.com (federal-mandated free version, not the paid services). Look for errors, paid-but-still-reported collections, and any open accounts you forgot about. Disputes typically resolve in 30-60 days. Improving from 680 to 740 before applying saves more than any other single optimization.

Once you have a price range, pick the loan type that fits your situation and shop 3-4 lenders. Most buyers pick a loan type and lender simultaneously without realizing they're separable decisions — and that picking the wrong lender costs more than picking the wrong loan type.

Loan type comes first. Conventional with 5-20% down is the default for most buyers with 660+ credit. FHA (3.5% down, 580+ credit) is the path when conventional won't approve or rates run materially higher than FHA. VA (0% down) is structurally the best loan if you're eligible. USDA (0% down) works in eligible rural areas. The FHA vs. Conventional calculator handles the most common decision; the Loan Types page covers every option.

Then shop lenders — not before. Most first-time buyers get pre-approved with whoever their realtor recommends. That lender may or may not have competitive pricing. The credit-bureau shopping window allows multiple inquiries within 14-45 days to count as a single shopping event, so there's no FICO penalty for getting 3-4 Loan Estimates. The pricing variance across lenders on the same borrower is typically 0.25-0.5 percentage points — that's $20,000-$40,000 over a 30-year loan on a $400K mortgage.

With pre-approval in hand, you can search seriously. Two things determine whether this phase goes well: the realtor you pick and whether you're reading listings honestly.

Realtors are paid on commission, and their financial interest doesn't always align with yours. A good buyer's agent earns their fee by helping you find the right house at the right price and walking through inspection negotiations. A weak one pushes you toward homes at the top of your approval (higher commission), discourages contingencies that protect you, and shrugs through inspection findings to keep the deal moving. The "How to choose a realtor" flagship guide covers the structural differences and the interview questions that distinguish them.

Listing prices often hide the real monthly cost. A $425K listing in a 2.5% property-tax state with a $250/month HOA produces a wildly different monthly figure than a $425K listing in a 0.7% property-tax state with no HOA. The Listing Reality Check calculator takes any listing's monthly-payment quote and shows you the full PITI+HOA+maintenance picture — usually 20-40% higher than the listing claims.

Once you've identified the home, the next decisions happen fast: offer price and structure, then rate lock once the offer is accepted. Both have real money attached.

Offer price isn't the same conversation as listing price. Listing strategy varies wildly by market and seller — some homes list under market hoping for bidding wars, others list above hoping for negotiation room. Your realtor should walk you through recent comparable sales (the last 90 days, similar properties, half-mile radius). If they don't, that's a flag from Stage 3 you didn't catch.

Rate lock happens once you have an accepted offer. The lock duration question is small in dollar terms but easy to get wrong. A 30-day lock is the default for purchase transactions because most contracts close in 30 days. If your timeline is longer (new construction, complicated title, contingency-heavy contract), get the longer lock from the start rather than paying for an extension later. Float-down provisions sound great and are often less valuable than they look.

The contract-to-close period is where most things can go wrong. Three milestones matter most: inspection, appraisal, and final closing cost picture.

Inspection findings drive the most consequential decisions in this period. Major defects (foundation, roof, HVAC, electrical) need either credit, repair, or walk-away response. Minor cosmetic findings are typical and rarely worth re-opening negotiations. Get a real inspector — not the cheapest one, not the one your realtor pushes. The home is the largest purchase you'll make; spend the $400-$700 on a thorough inspection.

Appraisal determines whether the lender will fund the loan at the agreed price. If the appraisal comes in below contract price, you have three options: bring more cash to close the gap, renegotiate the price down, or walk away (if your contract has an appraisal contingency). This is a structural deal-killer; understand your options before signing.

Closing cost final figure arrives 3 days before closing on the Closing Disclosure. Compare it line-by-line against your initial Loan Estimate — federal rules limit how much certain costs can increase, and any jumps should have an explanation. The Cash to Close calculator gives you the full upfront picture (down payment + closing + escrow setup + earnest money already paid) so you know exactly how much money to wire.

Closing isn't the end of the financial work — it's the beginning. Year one of ownership consistently surprises first-time buyers because the costs that don't show on the Closing Disclosure show up here: maintenance reserves, furniture and appliances, utility setup deposits, immediate cosmetic work the seller didn't credit you for.

Maintenance reserve is the single most ignored cost. Industry rule of thumb is 1% of home value per year. On a $400K home, that's $4,000 — and it accumulates, not as a regular expense but as occasional larger surprises (HVAC replacement, roof, water heater, appliances). First-time buyers who don't reserve this typically discover the issue when the AC dies in August and they need $8,000 they don't have. The True First-Year Cost calculator handles the year-one accounting honestly.

The first tax bill after closing is often higher than the seller paid because property tax reassessment typically happens at sale. If you're in a state with significant assessment differentials (Texas, California, Florida), budget for this.

House-poor risk shows up if you bought too close to the top of your qualifying range. The House Poor Risk calculator gives you the warning signs before they materialize. If you're seeing risk indicators, address them in year one rather than year five — refinancing, renting a room, or selling and renting is easier earlier than later.
