Buying a home is a process measured in documents. Offers, disclosures, inspections, appraisals, loan estimates, title reports — the stack grows with every stage. Your realtor and lender will guide you through the major milestones, but there is a dimension they rarely emphasize: nearly every document has an expiry date, and missing one can delay your closing, cost you money, or force you to start a step over.
Pre-Approval Letter: 60 to 90 Days
Your pre-approval letter tells sellers you are a serious, qualified buyer. But it expires in 60 to 90 days. If it lapses before you find a home, reapplying means another hard credit inquiry, updated documentation, and potential changes to your qualification.
- Request pre-approval early enough to be ready, but not so early it expires during your search
- Contact your lender proactively for a renewal if you are approaching the expiry date
- Keep your finances stable during the pre-approval period — no large purchases, new credit, or job changes
Tip: Some lenders issue letters valid for only 30 days. Ask about the validity period before you begin shopping.
Rate Lock: 30 to 60 Days
Once you have a signed purchase agreement, you can lock your interest rate for typically 30 to 60 days. If closing is delayed past the lock period, you are subject to the current market rate. Extending an expired lock costs 0.125% to 0.375% of the loan amount, and in a rising rate environment, the difference adds up over the life of the mortgage.
- Lock as soon as your agreement is signed and you are confident in the timeline
- If delays emerge, alert your lender immediately to discuss extension options
Home Inspection: 7 to 14 Day Contingency Window
The inspection contingency period in your purchase agreement is typically 7 to 14 days. Within this window, you must complete the inspection, review findings, and negotiate repairs or a price reduction. Missing the deadline may mean losing your right to negotiate — or your right to walk away without forfeiting earnest money.
- Schedule the inspection immediately after signing — popular inspectors book quickly
- Submit your response well before the deadline, not on the deadline itself
Tip: If the inspection reveals issues needing specialist follow-up, request a contingency extension in writing before the original deadline passes.
Appraisal: 120 to 180 Days
Appraisals are valid for 120 to 180 days depending on the lender and loan program. FHA appraisals are valid for 120 days with a possible 30-day extension. If closing is delayed past validity, a new appraisal costs $400 to $700 — and in a declining market, it could come in lower, jeopardizing your loan.
- Ask your lender about the specific validity period for your loan type
- Discuss appraisal update options (less expensive than a full re-appraisal) if delays seem likely
Title Insurance: Effective at Closing
An owner's title policy protects you for as long as you own the property. However, if closing is significantly delayed, the title company may require an updated title search to catch new liens or claims filed since the original search. Title insurance premiums are a one-time cost, but if your deal falls through, you pay again on the next property.
Keep your owner's title policy in a safe place — you may need it decades later if a defect surfaces.
Homeowners Insurance: Active Before Closing
Your lender requires proof of homeowners insurance on or before the closing date.
- Bind your policy at least one week before your scheduled closing
- Verify coverage meets lender requirements for dwelling, liability, and any area-specific hazards (flood, earthquake, wind)
- After closing, missing an annual renewal can trigger force-placed insurance from your lender at two to three times the normal premium
Tip: Compare bundled and standalone quotes. Bundling with auto insurance is not always cheaper.
Property Tax Deadlines
Missing a property tax payment results in penalties, interest, and potentially a tax lien on your property.
- Confirm whether your mortgage includes an escrow account that pays taxes automatically
- Know your jurisdiction's schedule — semi-annual, annual, or quarterly
- At closing, the prorated tax adjustment determines what you owe for the remainder of the year
HOA Documents: Review Periods
If your home is in an HOA community, most states give buyers a 3 to 15 day review period after receiving HOA documents, during which you can cancel the contract. After closing, track annual dues deadlines and any special assessments — late fees and lien rights apply.
Warranty Registrations: 30 to 90 Days Post-Closing
New construction and recently renovated properties often include builder's warranties, appliance warranties, and system warranties. Many require registration within 30 days of closing — unregistered warranties may default to shorter coverage or be voided entirely.
- Register all warranties promptly after closing
- Note separate builder's warranty periods: typically 1 year for workmanship, 2 years for mechanical, 10 years for structural
- Track every appliance and system warranty with its expiry date and claim contact
Post-Closing: The Deadlines Continue
After closing, a new set of recurring deadlines begins:
- Homeowners insurance — annual renewal
- Property taxes — semi-annual or annual
- HOA dues — monthly, quarterly, or annual
- Mortgage escrow review — annual (monthly payment may adjust)
- Home warranty — typically 1 year, renewable
- Appliance and system warranties — various expiry dates
- Flood insurance (if applicable) — annual renewal
