Most buyers experience a home purchase as a single event — signing day. Legally it is three overlapping processes running at once: a purchase contract governed by state law, a mortgage loan governed largely by federal consumer-protection rules, and a title and settlement process governed by state conveyancing practice. Each has its own paperwork, its own deadlines, and its own way of going wrong.
The good news is that the federal layer is uniform. Wherever you buy, a lender making a typical closed-end consumer mortgage must give you a Loan Estimate within three business days of your application and a Closing Disclosure at least three business days before consummation. Everything else — who conducts the closing, what taxes are owed on the transfer, how a deed is recorded — depends on the state and sometimes the county.
Key takeaways
- Preapproval is a lender's preliminary opinion; a commitment letter after full underwriting is what actually supports removing a financing contingency.
- Under the TILA-RESPA Integrated Disclosure rules, the Loan Estimate is due within three business days of application and the Closing Disclosure at least three business days before consummation.
- Closing costs split into lender charges, third-party services, title and settlement fees, government recording and transfer taxes, and prepaid escrow items.
- A lender's title policy protects the lender only; an owner's policy is the buyer's separate protection and is usually optional but often worth buying.
- Settlement custom is state law: some states use attorneys, others title or escrow companies, and transfer taxes and recording rules vary widely.
From preapproval to commitment
Buyers usually collect three different lender documents in sequence, and only the last one carries real weight.
| Document | Based on | Legal weight |
|---|---|---|
| Prequalification | Numbers you state, often unverified | None; an estimate for shopping |
| Preapproval | Credit pull plus some documentation review | Conditional; not a promise to lend |
| Commitment letter | Full underwriting, appraisal, and verification | A binding offer to lend on stated terms, subject to listed conditions |
This distinction matters because most purchase contracts tie the financing contingency to a date, not to a document. If your contract says the financing contingency expires on a fixed day and you have only a preapproval, you may be waiving your exit while your loan is still unwritten. The interaction between contract deadlines and lender timelines is one of the most common friction points in residential purchase agreements, and it is worth mapping before you sign.
What underwriting actually checks
Underwriters look at four things: capacity (income and debt), credit, capital (down payment and reserves), and collateral (the appraised property). A commitment letter typically lists remaining conditions — an updated pay stub, a letter explaining a deposit, proof that a prior property sold, evidence of hazard insurance. Those conditions are not formalities; a loan can be withdrawn if they are not satisfied, and lenders commonly re-verify employment and re-pull credit shortly before closing. Opening a new credit line or changing jobs between commitment and closing has derailed many otherwise finished transactions.
The federal disclosure clock
The Consumer Financial Protection Bureau administers the integrated mortgage disclosure rules that sit inside Regulation Z. Two deadlines drive the calendar for most consumer mortgages:
- Loan Estimate: due within three business days after the lender receives an application, showing estimated rate, monthly payment, cash to close, and itemized costs in a standard format designed for comparison shopping across lenders.
- Closing Disclosure: due at least three business days before consummation, showing final terms and an itemized settlement statement. Certain late changes — a switch in loan product, the addition of a prepayment penalty, or an interest-rate increase beyond specified tolerances — restart that three-day period.
Read the Closing Disclosure against the Loan Estimate line by line. Some costs may not increase at all from the estimate, some may increase only within a tolerance, and others may change freely; the forms themselves flag which category applies. Questions are far easier to resolve during the three-day window than at the signing table, and the CFPB's Owning a Home materials walk through each section of both forms.
Watch the deadline: "Three business days" is defined by regulation, not by common sense, and delivery methods affect when receipt is presumed. If you have not received a Closing Disclosure three days before your scheduled closing, ask for it in writing immediately rather than assuming the date will hold.
Where closing costs come from
Buyers routinely underestimate cash to close because the total is assembled from five unrelated sources:
- Lender charges — origination, underwriting, and any discount points paid to buy down the rate.
- Third-party services — appraisal, credit report, flood determination, survey, pest inspection where customary.
- Title and settlement — search and examination, settlement or closing fee, lender's title policy, and an optional owner's policy.
- Government charges — recording fees plus state, county, or municipal transfer taxes, which vary enormously; some jurisdictions impose none, others impose several layers.
- Prepaids and escrow — the first year of hazard insurance, prepaid interest to month-end, and the initial deposit into an escrow account for taxes and insurance.
Escrow deposits deserve attention because they are not fees. The money remains yours and pays your future property tax and insurance bills. If the tax assessment underlying that escrow looks too high, the remedy is a separate administrative process — see our guide to appealing a property tax assessment — not a negotiation with the lender.
Federal law also constrains who may be paid what. RESPA Section 8, implemented at 12 CFR 1024.14, prohibits kickbacks and referral fees for settlement services and bars charges for services not actually performed. That is the rule behind the requirement that affiliated-business arrangements be disclosed, and it is why an agent generally may not accept payment simply for steering you to a particular title company. The scope of an agent's duties in the transaction is covered in our discussion of agency and disclosure obligations.
Title, survey, and the settlement file
While the loan is underwritten, a parallel workstream examines the chain of title. The searcher looks for prior deeds, mortgages, judgment liens, tax liens, easements, restrictive covenants, mechanic's liens, and probate or divorce records that could affect ownership. The result is a title commitment listing what must be cleared before closing and what will remain as exceptions to coverage afterward.
Title insurance differs from other insurance: it looks backward, insuring against defects that already exist but were not discovered. The American Land Title Association, the industry's national trade group, publishes the standard policy forms used in most states. Two points to hold onto. First, the policy your lender requires protects the lender's lien, not your equity. Second, an owner's policy is a separate purchase, and once bought it generally lasts as long as you hold the property.
Wire fraud is now among the most serious practical risks at this stage. Criminals monitor transaction email and send altered wiring instructions in the final days. Confirm wire details by calling a number you obtained independently, never one supplied in an email.
What happens at settlement
- Final walkthrough. Usually within 24 hours of closing, to confirm the property's condition, agreed repairs, and that included fixtures remain.
- Document signing. The buyer signs the note, the mortgage or deed of trust, and the settlement statement; the seller signs the deed and transfer affidavits.
- Funding. The lender wires loan proceeds; the buyer's cash to close arrives by wire or certified funds. Some states fund the same day, others use a short escrow period.
- Payoff and disbursement. The settlement agent pays off the seller's mortgage and liens, pays commissions and taxes, and disburses the seller's net proceeds.
- Recording. The deed and the new mortgage are recorded in the county land records, which is what puts the world on notice of your ownership.
Who runs this table is a state-law question. A number of states require or customarily involve an attorney in residential closings; others rely on licensed title or escrow companies. Neither model is inherently safer, but the buyer's own protection differs: in an attorney state, someone at the table may represent you personally, while a settlement agent's role is generally neutral.
Frequently asked questions
Can a lender deny my loan after issuing a commitment letter?
Yes. A commitment is conditional, and the conditions matter. Lenders commonly re-verify employment, re-pull credit, and confirm that reserves remain intact shortly before closing. New debt, a job change, an unexplained large deposit, or a lapsed insurance binder can all cause a withdrawal. Keep your finances static between commitment and closing, and route any change through your loan officer first.
Do I have to buy an owner's title insurance policy?
Usually not — it is typically optional, while the lender's policy is required. But the lender's policy protects only the lender's lien. Without an owner's policy, an undiscovered defect such as a forged deed, a missed heir, or an unreleased lien is your problem to litigate. Because the premium is generally a one-time cost, many buyers treat it as inexpensive insurance against a low-probability, high-cost event.
What if the Closing Disclosure has an error?
Raise it before you sign. Some costs may not increase from the Loan Estimate at all, others only within tolerances, and lenders must cure excess charges. Errors caught during the three-day review window are corrected on paper; errors caught after funding require a post-closing adjustment that takes far longer. Compare the two forms side by side rather than skimming the bottom line.
What happens if I miss a mortgage payment later on?
Federal servicing rules give borrowers a structured window to seek assistance, and generally a servicer may not make the first foreclosure filing until the loan is more than 120 days delinquent. The practical answer is to contact the servicer early and read our guide to the foreclosure process and the options before a sale.
Putting it together
Treat the purchase as two calendars laid on top of each other. On the contract calendar, note inspection, appraisal, financing, and title-objection deadlines and who must act on each. On the loan calendar, note the application date, the Loan Estimate due date, appraisal delivery, commitment, and the Closing Disclosure delivery date three business days before signing. Where the two calendars conflict, ask for a written extension before a deadline passes rather than after.
Then read the documents in the order they arrive, not all at once at closing. The disclosure rules exist to give you time; using it is the single cheapest form of protection available to a buyer.
