I appreciate all the feedback. I pulled all sales up to 120 miles or so of similar quality homes on any amount of land, but the closest ones are 50-80 miles away. Many of them are nearly identical in quality/age and other factors. I just can't see them using anything that far away, but I am at least hoping they will maybe lean on 1 to show some type of difference.
Overall, I'm just hoping to see some type of acknowledgement of value of construction and finishes that do not resemble camper/RV quality finishes that have been painted over to look like that's not what they are.
Our immediate area consist of well kept manufactured on one side of the road, 400k-1mil+ on the other side of the road lol. I think that is why the property has gone over so well on the market---you are not getting into any 1200+ sf house fit to live in one acre here for under 350-425k. The whole time we were under contract with the first buyer, we had random people pulling up the drive trying to get info on it.
I did go back and reviewed the cost approach in the report. It put us at 250k overall, but Marshall Swift "replacement value" for the home was 60k under what the home sells for now before dealer markup (someone at the manufacturer was kind enough to white out the dealer mark up and send it to me lol). It doesn't seem like they gave the cost value any weight in the FHA appraisal.
I also hope that my posts don't come off as me being critical of the process. There are some definite issues, but I honestly feel like they are more with whomever did the appraisal either not being as...aware...of differences in these types of homes over the past few decades. Really even today there is a huge variance in quality from one to the next. Older ones are pretty common in the area, but zoning doesn't allow them in many of the neighboring areas.
I will try to update once I hear anything on the new contract's appraisal.
