If you have enough comps, with some luck you can see what some properties are doing in comparison to others with certain amenities. 

Real estate by comparison is riskier.

It dosn't mean what they push about thier market is wrong, but ultimately you should do your own data driven comparison.

One of my clients for whom we were building a duplex did not have any in her area so they had to pull comps from about 5 miles out to help create some sort of comparison.

I just see it as having two chances of having a successful avenue of communication :)If buyers will have to price match/comparison shop between the different fees, it just becomes a small nightmare for them. 

That'll give you a more apples-to-apples comparison. 

Incentizes the listing agent to find a buyer and the seller to accept it.If buyers will have to price match/comparison shop between the different fees, it just becomes a small nightmare for them.

I want to take things into my own hands and educate myself before I pay thousands of dollars to smart lawyers who use great marketing for themselfs...And also : Can anyone recommend any other lawfirm then anderson just for comparison purposes?

DSCR is what a bank would calculate so I'm unsure if the bank would use CapEx and a property manager in their calculations.I want to make sure I'm using apples-to-apples comparisons.

So it is almost never an apples-to-apples comparison.
