"Mike Anderson was the consummate professional and was very knowledgeable. We had a great connection and he followed through on getting both estimates completed during the timeline that we agreed to which was in less than a week. I would definitely recommend Accelerated Appraisals to my friends and family. I would just like to suggest paying closer attention to the small but important details prior to emailing the appraisals to the customer."

Property Appraiser FAQs, answered by experts

In most cases, you can expect home automation to boost your home value. This technology makes the homeowner’s life easier and more comfortable, and some provide increased safety and protection. Buyers will likely recognize value in security systems and utility monitors, as well as comfort-focused upgrades that save on electric bills while keeping interior rooms at the desired temperature and humidity. On average, you can expect a 50% and 75% return on investment on home automation services, and potentially even more if the automation reduces homeowner’s insurance.

Typically during transactions or refinancing, or whenever significant improvements are made.

Installing a flagpole can improve your home’s curb appeal, so it will often have a modest positive impact on your property value. You’ll see a much larger bump in property value if you install a custom wooden flagpole than you would if you install a standard aluminum pole. Adding lighting to your flagpole will also have a positive impact on home value, as will trimming trees away from the new lawn addition.

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 condition and appearance of your yard can affect your home appraisal value. A well-maintained, attractive yard with curb appeal adds to a property’s value, while an overgrown, messy, poorly maintained yard can hurt your home’s appraisal. Even small cosmetic improvements to your yard, like adding mulch, trimming trees, and cleaning out plant beds, can help your appraisal value.
