California homebuyer due diligence: a pre-offer checklist

A listing photo and an open house can help you decide whether to investigate a home. Before making an offer, build a short file of questions whose answers could change your budget or your willingness to buy.

Confirm the property facts

• Compare the listing with county records for lot size, permitted living area, and recorded ownership. Ask the seller or agent about any differences.
• Request the seller disclosures and read them alongside the inspection reports. Note repairs, water intrusion, drainage issues, and work completed without permits.
• If the home belongs to an HOA, request its current budget, rules, insurance summary, meeting minutes, and any notices of special assessments.

Estimate the full monthly cost

• Ask your lender for a current loan estimate based on the actual property and your financing terms.
• Obtain a property-specific insurance quote early. Coverage and premiums can vary by address and carrier.
• Check property taxes, special assessments, HOA dues, utilities, and any maintenance the inspection suggests.

Map location-specific risks

• Review official flood and wildfire maps for the parcel; a neighborhood label alone is not enough.
• Visit at different times to assess traffic, noise, access, and nearby land uses.
• Ask the relevant city or county about planned infrastructure or development that matters to you.

Keep a decision record

Write down each unanswered question, its source, the answer, and the date you verified it. Ask your agent and qualified inspectors which matters need resolution within your contract deadlines. This checklist is a starting point, not a substitute for property-specific professional advice.
