Buying a first home is less a single decision than a sequence of small ones, and the expensive mistakes usually happen before anyone reaches a closing table. Buyers who understand the order of events — budget, pre-approval, offer, underwriting, closing — tend to negotiate better, borrow less than they are offered, and arrive at the end with fewer surprises.
Here is how the process actually works, from the perspective of the advisors who sit on the lending side of it every week.
Start with your budget, not the lender's maximum
Pre-approval tells you what a lender will lend, not what you should borrow. The two numbers can differ by a hundred thousand dollars, and the gap is where stretched buyers get hurt. Work out your housing number from the bottom up: take your take-home pay, subtract retirement contributions, debt payments, childcare and the savings you want to keep, then see what remains.
Then add the costs that are not in the mortgage payment: property tax, homeowners insurance, maintenance at roughly 1% of the property value per year, and utilities. A home is a physical object that consumes money continuously, and a budget that ignores this is a budget that will be revised painfully in month four.
Get pre-approved before you look at houses
Pre-approval requires income documents, asset statements and a hard credit check, and it produces a letter stating the amount a lender will finance. In a competitive market, a serious pre-approval letter is often the difference between an offer being considered and being discarded.
What to have ready
Two recent pay stubs, two years of W-2s or tax returns if self-employed, two months of bank statements, and identification. For gift funds, lenders require a signed letter from the donor and evidence of the transfer. Gathering these before you apply routinely shortens the process by a week.
Compare at least three lenders on the same day so the enquiries count as one shopping event. Ask each for a Loan Estimate, which standardises the rate, points, fees and cash needed at closing. The headline rate is only one line on that document, and it is rarely the line that decides which offer is cheapest.
Understand the loan types before choosing
Conventional loans generally require a 620 score and 3–5% down, and mortgage insurance can typically be removed once you reach 20% equity. FHA loans accept lower scores and smaller down payments but often carry insurance for the life of the loan. VA loans offer strong terms for eligible veterans and usually require no down payment. Jumbo loans sit above the conforming limit and carry stricter underwriting.
The right choice depends on your score, your down payment, how long you intend to stay and whether you can remove insurance later. Buying points to lower the rate only makes sense if you keep the loan long enough to break even — a number you can calculate exactly, and one we calculate for every client.
A mortgage is a thirty-year decision made with a thirty-day perspective. Slow down at the document stage; it is the cheapest hour you will ever spend.
Budget for closing costs separately
Closing costs typically run 2–5% of the purchase price: lender fees, appraisal, title insurance, recording fees, prepaid interest, escrow deposits and, where applicable, transfer taxes. On a $350,000 home that is $7,000 to $17,500 in addition to the down payment, and it must be verified as sourced and seasoned in your account.
Buyers who spend their entire savings on the down payment frequently end up financing the closing costs, arriving in the new home with no reserve. Keep a separate emergency fund for the property itself; the first year of ownership has a habit of producing an unplanned repair at the least convenient moment.
The underwriting stage is where deals are won or lost
Once your offer is accepted, do not open new credit, change jobs, move large sums between accounts or make significant purchases until closing. Underwriters re-pull your credit and re-verify employment shortly before funding, and a new car loan in week three can genuinely unwind an approval.
Respond to document requests the same day where possible, and keep every page of every statement. Most closing delays we see are not caused by the lender's appetite but by a missing page or an unexplained deposit. When the file is clean, closings happen on schedule.
Finally, do a final walk-through the day before closing, confirm the settlement statement matches your Loan Estimate and ask about anything that changed. Then sign, take the keys, and put the first month's payment into your budget as though it has always been there — because for the next thirty years, it will be.
