Yes, installing a tennis court can be a worthwhile home improvement project that adds value to your property. The potential increase in value can range from $20,000 to $150,000, and in some cases, the return on investment can cover more than 60% of the installation cost. However, the impact on value heavily depends on the size of your property. For homes with multiple acres, a tennis court is often a valuable amenity. In contrast, for homes on smaller lots, installing a court can decrease the property's value because it consumes a significant portion of the usable yard space. It's crucial to consider your property size and the remaining usable yard before proceeding.

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.

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. 

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.
