Looking at a house and possibly going to put an offer in. I'm curious, if there's no comps, what does an appraiser base the appraisal on? The house we're interested in is located in a neighborhood that doesn't typically have homes go on the market. We're in a very small town, and a smaller house on approx. the same size lot sold about 8 months ago, but in terms of other similarities, it pretty much stops there. That house sold for ~ $272k, this house we're interested in is listed at $344,900, which is crazy to me considering my town's market. Just curious how an appraiser would go about appraising this property with no good comps.
Appraiser's use the sales of other homes to assist in determining the current value of any home. It doesn't need to be in the same neighborhood, or on the same street or even in the same town for that matter, but the closer it is, and the more of them there are, the better. They use a lot of different criteria to assess the value of a home not just comps.
I took the course to be a RE appraiser many, many moons ago but never made it official. Frankly, I found the job way too boring. And it was too long ago to remember all the intimate details but I do recall being surprised at just how much goes into the task. Lots of calculations and formula's are applied. How in depth the appraisal gets from a documentation perspective depends on what the appraisal is for and to a great extent what the customer is willing to pay.
Assuming the thread will continue, what is the basis for your question? If the home is on the market for that price, there may very likely have been no appraiser involved. RE people may have come up with the number or worse, the sellers may have come up with a value that for all you know has no basis in reality. Is the value coming from the tax rolls? Is it a foreclosure? I think you may see what I'm getting at.
If it's a house you're truly interested in, you could get a professional appraisal for your purposes for several hundred dollars. If you hire someone they are obviously working for you. The lender isn't, the RE company isn't and the taxing authority certainly isn't.
