Not to scare you but an interesting note:
I recently had 2 appraisals done on the same property by 2 different appraisal companies and the difference in value was $200,000 between one appraisal and the other. I did my own research in advance, gave both appraisers the same info package showing renovations, rental income and comparable sales in the area. Now, it was a unique property, no very obvious direct comparisons, therefore a little more difficult to analyze, but when I went over the appraisals thoroughly after the fact and asked a lot of questions to better understand how each appraisers came up with their valuation, I was quite surprised by some things that I heard.
I would suggest doing your own research first, talk to a realestate agent who knows that area and go over comparable solds, look at these properties and decide for yourself how they compare to your property. Once you have an idea of what you think the value is, then bring in an appraiser who knows the area really well. Each party should probably have their own appraisal ,unless of course you can amicably agree on value, which would be the best course of action.
Even though it`s not a realestate agent`s job to valuate property, their opinion is beneficial because there`s a good chance that they have actually been inside and seen some the recent comparable sales and can give you feedback as to how your property compares. The appraiser has probably not seen these properties himself, his valuation is on more tangible things like square footage, #of bathrooms, parking spaces, and has to rely on the fact that the information he is getting from mpac and the mls listing is accurate. One of the comparables used by both appraisers said "renovated" but failed to say what decade. I had looked at this property when it was for sale and it hadn`t been updated since the mid `80s. It`s not an appraisers job to go and look at these comparables in person, just to analyze the info given. Another comparable was attached to a halfway house for schizophrenics but that information isn`t on the listing. Do your due diligence, use the help of a realtor to figure out what you think a fair market value is, get a professional appraisal (or two). And make sure you really look at the appraisal and keep it handy for future. When a bank gets an appraisal done on your house, you generally won`t have access to it, but when I`ve paid for it myself I find it`s worth it`s weight in gold. I learn so much.
Hope this helps
