Antiques and Jewelry Appraisals questions, answered by experts

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.

Yes, built-in bookshelves can be worth the investment and can add value to your home, especially when constructed from high-quality, timeless materials like luxury hardwood. They offer a practical and stylish storage solution that utilizes wall space effectively. While they cost more than store-bought units, the custom fit and potential to increase your property's resale value make them a desirable feature for many buyers, particularly for homeowners with large book collections. For the best return on investment, consider having them professionally built.

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.

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.

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.
