That may or may not be the case. And the fact I've driven by a house 30 times in the past year does not mean I paid attention to the least of details. Sure we can go into a subdivision of 10 years age and see that all the houses are similar on the outside. And we have pictures in the MLS....when we have an MLS and I work areas where there are few Realtors and some do not belong to any board nor MLS. And as a rural appraiser, many sales, particularly land, are not sold by a Realtor. I need to see what I am looking at because if a complaint is filed, you can bet the investigator will go look at them. I had a comp, not unreasonable for price, of an older Manf. home, looked typical in the MLS but when I arrived there to take a picture, all I found was a pile of blocks that was once the foundation. The MH was gone. This was a land sale...great for determining the site value, but not a comp for a functional HUD code home.
