Antiques and Jewelry Appraisals questions, answered by experts

Estate shutters are considered a high-end window treatment that increases home value. As previously mentioned, this project comes with an ROI of up to 75%. Shutters can also improve your home’s energy efficiency, especially if you choose PVC or faux wood shutters, which will lead to long-term savings on your energy bills.

While a finished basement adds value to your home, it is assigned a different value than space on the main floors. An appraiser will assess the square footage of a finished basement at about 50% to 60% of the value of the square footage for the rest of your home. Appraisal value for a finished basement depends on your location’s real estate market and the specifics of the basement and how it was finished. 

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.

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

Xeriscaping can absolutely increase your home value, but the return on investment (ROI) depends on where you live and how prevalent xeriscaping is in your area. In drought-prone climates, xeriscaping can boost your curb appeal and make your home more appealing to buyers due to the reduced maintenance and watering costs. However, in areas where xeriscaping isn’t the norm, some buyers may be willing to pay less for a xeriscaped property if they don’t like the appearance.
