They have in-house products for Fannie Mae non-warrantable and I have strong financial reserves, so we are confident that we can close the deal. 

Personally, I don't consider two years to be long enough to warrant buying a house.

I have read and watched several videos on anonymity in the rental property business and wondered if this was an issue that any of you feel warrants utilizing an attorney as the registered agent?

If warranted, a meeting is set up with the individual to discuss the details of what they are doing.

Apples to apples if the same condo that is warrantable is selling for 500k I'm thinking this should be 470k - 475k. 

Otherwise you need a lender willing to lend on  a non-warrantable condo in Cook County. 

I keep seeing properties on MLS and similar sites in my area of Wichita KS where the asking price is 15-20% higher than what the local appraisal values the property.For instance , if the physical property has a value of 100k , but the asking price is 120k, does the the fact that there are existing leases in places warrant a 20% markup in the asking price?

The condos rent for 1500 but be careful as most condos are non warrantable.

because the industry as a whole is starting to warrant more and more attention.  

It's where I own a condo and also do most of my business, so I can assure you your interest is warranted.
