Legal Question in Real Estate Law in Pennsylvania

Get the property appraised and find out what comparable properties in the area are worth if this is land. You can do this by either hiring one appraiser and agree to be bound by the appraisal or you can each hire your own appraiser, and let the 2 appraisers select a third appraiser for whom you will split the costs. When you get all three appraisals, then average them and take the average amount. That is the most fair way that I know how to do it.

If this is anything other than land (like a business), it can be valued in much the same way. There are companies or individuals who are business valuation experts.
