When buying or refinancing, an appraisal is almost always required (there are a few exceptions).

What is an appraisal? It's simply an independent opinion of your home's value, performed by a licensed home appraiser.

Here is what they do:

First: they find a starting value based on the recent sales prices of homes that are comparable to yours in terms of bedrooms, bathrooms, style, and square footage in the same area as your home

Then, accounting for features and amenities that make your home different, the appraiser applies "adjustments" to that starting value. Once all the adjustments are accounted for, you will have your final appraised value.

As homeowner, you can't affect the sales prices of your home's comparable properties, but you can help your appraiser understand how your home stands apart from these homes. This, in turn, can affect your home's adjustments, resulting in a higher appraised value.

With home appraisals, every valuation dollar can matter. With that in mind, here are a few tips for maximizing your home's appraised value:

1. Be home for your appraisal so you can answer the appraiser's question, if there are any.
2. Mention any new roofing, flooring, HVAC, plumbing, or windows you've installed since purchase.
3. Don't mention projects or repairs you're "about to undertake". Appraisers don't credit for unfinished projects.
4. Make minor household fixes prior to the appraisal (e.g.; leaky sink, running toilet, peeling paint).
5. Present a tidy home. This can contribute to a higher "overall condition" adjustment.
6. Schedule the appraisal for a time that is convenient for your entire household. An appraiser needs to see, measure, and take photos of every room in your home. If a room's door is closed because of a resting child, for example, the appraiser may need to schedule a second appointment to complete the appraisal, and that can raise your appraisal costs
