If you can’t find any records online, you’ll need to contact your county clerk’s office to do further research. They should have property records on file, or can at least point you in the right direction of who to contact. You can also speak with your neighbors about when their houses were built because they were likely built around the same time.

Ideally, you’d never pay more than the appraised value for a home, but there are some instances where it makes sense to do so. For example, if your current living arrangements are no longer viable and you need a place to move into quickly, paying more than the appraised value might be in your best interest to secure a new home. Additionally, if you’re buying in a hot market, overpaying for the home might be necessary to overcome the competition.

While there’s technically no limit to the dollar amount you can borrow for a home addition, the standard limit is around 80% of the value the addition is expected to add to your home. That means you could feasibly borrow up to $80,000 if an appraiser determines that the addition or bump out will add $100,000 in value to your property. You might also be limited by your debt-to-income ratio or credit score.

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.
