It’s hard to compare when they are using different numbers.

I wish to use these to compare against Gross SF to see if there are any opportunities to add a unit or add in addition bedrooms, etc.THANKS!!

Let's take another angle, say your credit debt was relatively low compared to your ability to create cash flow from an investment.  

I feel like my area the prices are somewhat high compared to what I’ve heard others talk about but then I thought perhaps it had to do with the ages of the buildings in New England.

Plus, after being a part of the club and learning so much more about corporate real estate and that side of the world compared to what most people think when they hear real estate, which is the “residential or real estate agent” assumption.

(I don't need immediate cash flow and care more about total long term returns).Relatively affordable compared to other large cities (though the same is true for  SFHs). 

The last part is a moving target, especially these days, but unless you live in a really small area you can usually find similar houses that have sold, compare how well they are fixed up and where they are, and get a pretty good idea.

Have your agent manifest sold comparables within the past 90 days to give you a sense of what the market is taking.

If there are limited comparable properties, especially direct comparable properties, this makes appraising a property more uncertain and thus places greater liability on the appraiser.  

You can then compare that to the company you mentioned and pick the best fit for you.The primary item to watch for would be prohibited transactions.
