"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

In most cases, installing a tennis court on your property will drive up your property taxes. Property taxes are determined, in part, based on improvements made to your property, which includes anything with a permanent foundation. Since most home tennis courts include a large concrete foundation, your property taxes will likely increase following the installation. A general rule of thumb is that if your project requires permits—like for a foundation or fencing for a tennis court—then your property taxes will be affected.

Whether or not new windows increase property taxes depends on where you live and by how much your upgrade increases your home’s value. Smaller projects likely won’t result in increased property taxes, but it’s always a good idea to err on the side of caution and check. Contact your local county appraisal department for the most accurate information about property taxes in your area. 

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 there's not a lot of definite research, some experts suggest that an in-ground or wall-mounted basketball hoop can add value to your home by increasing curb appeal. In addition, having a basketball hoop is an attractive feature of a house since it promotes physical activity, especially for children.

As a seller, it might feel tempting to skip the appraisal, especially in a hot market that sees a lot of all-cash offers. While you can technically forgo it and hope for an all-cash offer, you’ll likely have a very tough time selling without an appraisal. 

In addition to protecting lenders from risk, appraisals also protect buyers’ investments. As such, it isn’t typically recommended for buyers to skip appraisals.
