Josh, I'm a commercial/residential appraiser in So CA. In March, I'll mark 40-years as an appraiser. Unfortunately, in this era, you, THE BORROWER has to know as much, if not more that any appraiser about your market area to protect yourself.
First, get a copy of this report - the law says you are entitled to one. Then, get in your car and drive the Comps the appraiser used to decide for yourself how "comparable" they are. Take photos of the Comps, I assume that these Comps are also large acreage properties.That way, you have documentary evidence about the Comparables.
Since, again these may be large acreage properties, try to get on each property to have a 1st hand look at what amenities they have, or not have. Were the Comps all close to 100-acres? If not, what kind of a land adjustment did the appraiser use? Did he/she assemble land sale comparables to make a market-derived adjustment, or did the appraiser just throw a dart at a land adjustment on the Land Adjustment Dart Board?
Next, If you're not a Member of the local MLS Board, hopefully you have an Agent friend who is. Have this person print out the listings for all of the Comps the appraiser used to compare the listing data with what the appraiser noted in his/ her report. Are their any discrepancies in the data? What did the appraiser miss?
Also have the Agent (or you) print out all comps the appraiser SHOULD HAVE USED. Don't cherry-pick, print out the Comps that are most similar to your home. If any Comps have a low sales price, determine why - bad condition, smaller lot/house, etc.? Note that to the appraiser
With respect to the neighbors house, you definitely need the sale listing for this property. Be sure to get the photos in the listing also. Hopefully this Agent put many photos in this listing, especially the interior. This way, you can show how inferior the condition of this Comp is. Will the Listing Agent verify that this Comp was indeed a fire sale? If so, tell the appraiser to do his/her own verification about the fact this is a "fire-sale" The appraiser should have verified the Comp in the first place, but in any case, if the condition of the property and the fact it was a fire sale is correct, the appraiser SHOULD NOT have placed most weight on this property.
Good luck with getting an appraised value you can deal with.
