"Elmer was very professional on my land appraisal. He made two trips to the planning department in order to determine the highest and best use of my land based on San Jose's zoning and building requirements. Elmer was very easy to contact by phone. He always answered his phone or readily called me back. I would gladly use him to do any future appraisals."

Property Appraiser FAQs, answered by experts

While there’s technically no limit to the dollar amount you can borrow for a home addition, the standard limit is around 80% of the value the addition is expected to add to your home. That means you could feasibly borrow up to $80,000 if an appraiser determines that the addition or bump out will add $100,000 in value to your property. You might also be limited by your debt-to-income ratio or credit score.

Depending on the size of the home, the appraisal itself can take several hours. After the appraiser’s visit is complete, it can take between a few days and a few weeks to get the report back. This timeline is largely dependent on the appraiser’s workload, research requirements, efficiency, and other factors.

Foundation cracks won’t always affect your appraised value. All foundations crack due to normal settlement, so hairline cracks that aren’t leaking or uneven from side to side are unlikely to have an impact on your appraisal. Structural cracks, on the other hand, often lead to a reduced appraised value, especially if the underlying problem will cause the issue to worsen over time.

The differences between market value and appraised value depend on the local market, so they can match, or either one can be higher than the other. In a “seller’s market,” where there is an abundance of buyers, market value will likely sit higher than the appraised value because there’s more demand for the low inventory of homes. In a “buyer’s market,” where there are more homes than there are buyers, the market value is more likely to sit below the appraised value to entice buyers.

While a finished basement adds value to your home, it is assigned a different value than space on the main floors. An appraiser will assess the square footage of a finished basement at about 50% to 60% of the value of the square footage for the rest of your home. Appraisal value for a finished basement depends on your location’s real estate market and the specifics of the basement and how it was finished.
