Property Appraiser questions, answered by experts

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.

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.

Yes, home appraisers look at your windows when appraising your property to determine the market value of your home. They’ll factor in the type of windows, quality, condition, whether or not there are screens covering the windows, frame materials, size, insulation, and more to come up with an unbiased property assessment.

Yes, appraisals are often used for property tax appeals, estate planning, and determining market value.

Basement bedrooms can count toward your room count and the square footage of your home on an appraisal if they’re fully legal, which means they have proper ventilation and points of egress, as defined by your local building code. Simply partitioning off a space for a bedroom in an otherwise unfinished basement that isn’t a legal living space won’t affect your appraisal value.
