Antiques and Jewelry Appraisals questions, answered by experts

Yes, awnings can add value to a home, primarily by boosting its curb appeal and providing more usable outdoor space. While the exact monetary return on investment depends on the awning's size, style, and quality, they offer an excellent appeal factor to potential buyers. For example, an awning with a trendy metal roof can be particularly attractive. Even if the direct increase in resale value is modest, a well-chosen awning enhances the home's functionality and aesthetic.

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.

Wainscoting isn’t a design element that can be directly tied to an increased house price. Despite that, it is a highly marketable element that can generate significant interest from potential buyers who enjoy the style, and is relatively inexpensive to remove for those who don’t. If you are on the fence about paneling, just know that it certainly wouldn’t result in depreciation of your home’s value—usually the opposite. 

While some aspects of an appraisal, such as comparable properties nearby, are out of your control, there are several steps you can take to potentially increase your home's value. Make any necessary repairs and upgrades before the appraiser's visit, as they can only value what is currently part of the home, not its potential. Examples include renovating older areas, updating landscaping to boost curb appeal, and staging your home. You can also provide the appraiser with the cost of recent upgrades, which may increase your home's value by about 50% or more of what you paid for those improvements.

Yes, experienced appraisers handle a variety of property types with tailored methods.
