Terms A to E

Appraisal: The lender’s independent opinion of what a home is worth, based on its condition and recent nearby sales. It protects the lender’s collateral, and when it falls short of the price the deal usually needs a renegotiation, more cash or a different loan.
Base-year value (Proposition 13): California’s property tax is built on a purchase-price base. Buy a home and its taxable value resets to what you paid, then can rise by at most 2% a year, which is why long-time owners often pay less than new neighbors in identical homes.
Local example: For a typical ZIP 92154 home at $750,299, the 1% base tax would be about $7,503 a year, or roughly $8,628 with an assumed 0.15% for voter-approved charges. Real bills vary by address and by any special taxes.
Closing costs: The fees due at closing on top of the down payment: loan charges, title and escrow fees, recording fees, and prepaid taxes and insurance. The Loan Estimate and the Closing Disclosure list them line by line.
Comparative market analysis (CMA): To price a home, an agent looks at sold homes of the same size, style and condition on nearby streets and adjusts for differences. The result is a CMA: a guide for pricing, not a formal appraisal.
Rudy prepares a personal market report on request, with the sold and current homes closest to yours.
Contingency: A condition in the purchase contract that lets the buyer cancel and keep the deposit if it is not met, most often for the home inspection, the appraisal, the loan approval and the review of disclosures. The standard California contract commonly gives about 17 days for these.
Earnest money deposit: Money the buyer puts into escrow after an offer is accepted to show they mean it. It is not an extra cost, because it is credited at closing; whether it can be lost depends on the contingencies and deadlines in the contract.

Terms E to P

Escrow: The neutral middle ground of a sale: an escrow company takes custody of the money and the documents, follows the instructions both sides signed, and closes the transaction once every condition in the contract is met.
HOA and CC&Rs: Buying into an HOA means agreeing to its rules and paying its dues. During escrow you receive the CC&Rs, the budget and the reserve study, and reading them can tell you a lot about the community’s health.
Local example: Newer Otay Mesa communities often have associations; ask which apply to the home and what they charge.
Mello-Roos (community facilities district): A Mello-Roos district is a way of paying for streets, sewers, schools or parks in a new community with a special tax on the properties that benefit. It is billed with the property tax and generally ends on a fixed date.
The San Diego County Assessor publishes information on Mello-Roos; ask whether the address is in a district.
Months of supply: Months of supply asks how long the current inventory would last if no new homes were listed and sales continued at the recent pace. Fewer months generally helps sellers; more months generally helps buyers.
Local example: In the week ending Sep 19, 2026, the San Diego metro area (San Diego–Chula Vista–Carlsbad) had 3.4 months of supply.
PCOR and the homeowners’ exemption: When a property changes hands, the buyer completes a Preliminary Change of Ownership Report so the assessor can update the records. Owner-occupants can then claim the $7,000 homeowners’ exemption.
Pre-approval: Where a pre-qualification is a conversation, a pre-approval is paperwork: the lender pulls credit, checks income, assets and debts, and states in writing what it is prepared to lend, subject to the appraisal and final underwriting.

Terms S to T

Supplemental tax bill: Watch for supplemental tax bills in the months after closing. They reflect the new, higher value from the date of the sale and arrive separately, so set the money aside.
Title insurance and the preliminary report: Title is the legal right to own a property. Title insurance covers problems from the past, such as an unknown lien or a forged signature, and the preliminary report is the title company’s early look at what is on record.
Transfer Disclosure Statement: The seller’s written list of what they know about the home: its systems, any defects, past repairs and work done without permits. It is one of several disclosures a California buyer receives.
Typical home value: A “typical” value is a statistical midpoint for an area’s middle-tier homes, from Zillow’s index. Use it to follow a trend, not to price a home; your street and your home’s condition decide the price.
Local example: Zillow’s typical home value in Aug 2026 was $750,299 in ZIP 92154.
