Conditon of apartment is at time you take possession, so do a walkthru on that apartment within the first week or so of ownership.Ask owner to send or drop off to tenant letter of change of ownership this is usually done day of closing, and you also send or drop off letter of introduction including where and how to pay rent, and emergency service contact info. 

Property radar by FAR is the best out there @Sean OToole and Sean is far to humble to toot his own horn :)Liz even though you would never use it you should subscribe or maybe Sean will give you a trial ... its only 50 a month or so.. and you can see how comprehensive this site is..

I already know the taxes for both properties and I have called the utility companies to get a round about number for utilities, but I wasn't sure if there is a specific document that may give me a comprehensive overview of the profits and losses for the current owner. 

If you are over 50-60% start systematically reducing the introduction of moisture and increase ventialtion.Make sure the basement is dry, if not check your gutters, downspout extensions and get a dehumidifier.

I've had all 3 be different before, then still the tenants claim something different at our post-closing introduction.

Extremely simplistic reasoning, beyond normal comprehension. 

i.e. area's, number of bedrooms etc.Estate agents wont be too forthcoming with introduction fees but an off market source of property should be able to reward you.

Of course that's no guarantee it can't be repealed, but I would think it very unlikely especially noting our current POTUS's comprehensive real estate activities.

Let me know if you want me to make an introduction.
