I'll give some numbers and an explanation of what I'm looking at for my first deal.A long time friend is looking to cash out of his duplex rental property to get away from tenants and pay off his primary home.

I currently represent numerous investors (both local and out of State) in the New Albany, Clarksville, Jeffersonville Areas.  

In speaking with numerous local property managers and some local investors, as well as combing through available 1/1 apartments for rent, I have come up with $600-625 a month being market rent.

The website has numerous resources - check out the tools tab at the top of the screen. 

If your client overlooked that then he is at fault, but could prevail if sec dep statement was not sent out with explanation in give state time period.If the landlord failed to give him a security deposit statement (why sec dep was withheld) within 30 days or 60 days per lease, in the mail, written, then landlord is in default and he could prevail in court.It really doesn't matter that the client didn't actually live in the apartment, during his waiting period, he still had rented it and landlord couldn't re-rent until notice was given.Like you said your client took a gamble it's unfortunate, he's lucky to have a advocate like you. 

Buy new stove and raise the rent to market value with explanation of it to the tenant.

Looks like some Atlanta condo building is fighting its residents over Airbnb ... and this building happens to be a condominium where numerous state legislators own.

Here is a very good explanation/example of COCR: http://www.propertymetrics.com/blog/2013/11/14/cas...COCR is just one of the MANY things to consider when evaluating a potential purchase. 

As I said there, I'm not sure it's a thing that can actually be done, but if not, maybe my explanation of what we're trying to do will spark some ideas in other community members with more experience and know-how and maybe we'll be lead to another method of achieving similar results. 

But I think you missed the point, or perhaps my explanation was not clear enough.
