My name is Lonn Apfel. I have been both a licensed, general appraiser and a real estate broker for over the last 48 years within the Inland Empire, east Los Angeles county and Orange County. My expertise is primarily focused upon residential home values. I believe that the combination of being both appraisal/real estate broker provides you, my client, with a deeper sense of value and market trends which are not typically found in either of the two worlds. I look forward to the opportunity to speak with you, helping to identify your needs and how I may best meet those needs.

"I was referred to Lonnie Apfel and he did not disappoint! He was polite, professional, honest and very knowledgeable. He completed the job on schedule as promised. I would recommend Lonnie without hesitation!"

Property Appraiser questions, answered by experts

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.

Basement bedrooms can count toward your room count and the square footage of your home on an appraisal if they’re fully legal, which means they have proper ventilation and points of egress, as defined by your local building code. Simply partitioning off a space for a bedroom in an otherwise unfinished basement that isn’t a legal living space won’t affect your appraisal value.

In most cases, installing a tennis court on your property will drive up your property taxes. Property taxes are determined, in part, based on improvements made to your property, which includes anything with a permanent foundation. Since most home tennis courts include a large concrete foundation, your property taxes will likely increase following the installation. A general rule of thumb is that if your project requires permits—like for a foundation or fencing for a tennis court—then your property taxes will be affected.

A koi pond may add value to your home if it’s a feature sellers are looking for. Like pools, ponds can affect your property value depending on their condition, whether they’re a popular selling point, and how well they’re incorporated into your home’s landscape.

Some appraisers hold a Member of the Appraisal Institute designation. This accolade is the highest credential property appraisers can earn. An MAI appraisal is typically used for commercial properties.

While your lender will likely recommend an appraiser, you can also hire a professional home appraiser on your own. Choose someone who is experienced in your type of residential property, and ensure they hold all of the necessary credentials that your state or region requires.
