The profession is more broad than doing bank loans.A good friend and neighbor of mine has a national appraisal company specializing in commercial properties, mostly retail development and he has been very successful.

If the problem is only indoors, it's likely that the carrier only has the high end of the spectrum in that area (or your walls are limestone/lead).

I'd suggest you do some reading as that is a general and very broad inquiry.

Your question is pretty broad so I will try to answer as best I can.When looking at the property you do want to look at the neighborhood.

Shale production is on the expensive end of the spectrum, so those projects are the first to be turned off.

I would not paint that broad of a brush as to the realtors.

I've seen a few cases of this in my career where seasoned investors stepped into the poop pile and lost big.I know of a case now where a sharp old broad is running a seasoned investor through the wringer with the above scenario along with elder abuse charges.

I don't think you can paint with too broad of a brush about landlords getting creamed and more than you can about material costs going up and fix-and-flippers getting creamed.This debates in the abstract are always simple minded.
