Home Buying Guide
The steps to buy a house, ordered as decisions
Most guides describe the paperwork. The paperwork is the easy part. What actually determines whether you are happy in five years is a short sequence of judgment calls: what the purchase is for, what you will pay monthly, where you will live, and what you are willing to trade away. This guide walks the ten steps in that order, with the question worth answering at each one.
1. Decide what the purchase is actually for
Before financing or listings, name the job the house has to do: how long you plan to stay, who lives there in five years, and which parts of daily life it must make easier. Every later tradeoff is judged against this.
The question
How long do we realistically hold this house?
Where it goes wrong
A three-year horizon rarely survives closing costs plus agent fees on resale.
2. Set a budget from cash flow, not from a pre-approval
A lender's maximum is an underwriting limit, not a comfort level. Work backwards from the monthly payment you would still be relaxed about after a job change, then add taxes, insurance, HOA dues, and a maintenance reserve of roughly 1% of the home value each year.
The question
What monthly payment stays comfortable in a bad year?
Where it goes wrong
Property taxes and insurance often reset upward after a sale — the seller's numbers are not your numbers.
3. Get pre-approved and understand the loan you chose
Pre-approval verifies income, assets, and credit, and makes your offer credible. Compare at least three lenders on rate, points, and lender fees on the same day, since rates move.
The question
Which loan structure fits our holding period?
Where it goes wrong
Points paid up front only pay off if you keep the loan long enough to recover them.
4. Define the search area before browsing listings
Choose areas by commute, schools, noise, flood exposure, and how far prices stretch. A house is largely a bet on its block; the block is the part you cannot renovate.
The question
Which two constraints will we never compromise on?
Where it goes wrong
Open-ended searching quietly drifts toward whatever is currently available rather than what you wanted.
5. Tour homes with a fixed evaluation checklist
Compare each home against the same list: layout, light, storage, systems age, parking, outdoor space, and street conditions at different times of day. Photograph mechanical rooms, panels, and water heaters.
The question
Is this house better than the best one we've already seen, and why?
Where it goes wrong
Emotional attachment to a staged home reliably outruns the evidence.
6. Investigate the things listings do not tell you
Check flood zone, permit history, roof and HVAC age, tax assessment trends, planned nearby development, and comparable sales in the last six months. This is where most avoidable regret is prevented.
The question
What would have to be true for this to be a mistake?
Where it goes wrong
Unpermitted work and deferred roof replacement are common, expensive, and rarely disclosed clearly.
7. Make an offer built around your leverage
Price is one term among several. Closing timeline, contingencies, repair credits, and rate-buydown contributions all move real money. Know your walk-away number in writing before you submit.
The question
Which terms are we willing to trade, and which are we not?
Where it goes wrong
Waiving inspection to win a bid transfers unknown repair costs directly onto you.
8. Inspect, appraise, and renegotiate on evidence
Use the inspection to price the next five years of the house, not to demand cosmetic fixes. If the appraisal comes in low, you can renegotiate, bring cash, or leave — decide which in advance.
The question
Which findings are deal-changing versus merely annoying?
Where it goes wrong
Structural, drainage, electrical, and sewer issues dominate the cost distribution; paint does not.
9. Clear the loan, insurance, and title work
Lock the rate, secure a hazard policy (and flood coverage where relevant), review the title commitment for easements and liens, and avoid new credit or large deposits before closing.
The question
Has anything changed about our income or debt since pre-approval?
Where it goes wrong
Late-stage credit activity is a routine cause of loan denials days before closing.
10. Final walkthrough and closing
Confirm agreed repairs, test appliances and systems, and check that nothing was removed. At closing, reconcile the Closing Disclosure against your Loan Estimate line by line.
The question
Does the settlement statement match what we agreed to?
Where it goes wrong
Fee changes between estimate and disclosure are common and are worth questioning.
How long each stage usually takes
| Stage | Typical duration |
|---|---|
| Budget and pre-approval | 1–2 weeks |
| Searching and touring | 1–4 months |
| Offer to accepted contract | 1–10 days |
| Inspection and renegotiation | 1–2 weeks |
| Underwriting to closing | 3–6 weeks |
Durations vary by market and lender. Treat them as planning ranges, not commitments.
Where Cortex fits
Steps 5 through 8 are where buyers lose the most money and gain the least clarity. Cortex takes a listing you are considering, researches the surrounding facts, and returns a Decision Brief: what is strong, what concerns it, what remains unknown, and what to negotiate. It does not decide for you — it makes the tradeoff visible before you commit.
