@Jd Martin BP Landlords bandy the "professional tenant" dogma anytime a tenant holds you accountable for illegal activities.Your naked allegations don't hurt my feelings, and you can't and won't minimize or neutralize your liability.

I suggest getting a POBox or having it sent to another neutral location.

For oak floors (assuming solid hard wood and not laminate), I would let the Natures miracle soak into all the cracks so it seeps in where the pee is to neutralize those areas.

Its neutral in most cases and easily covered by area rugs or carpeting to accommodate many tastes.  

Understanding, about neutral colors and flat paints.

Staying neutral is the best way to go whether its beige or grays.

Or, better yet, a neutral third party person who may be able to be witness to the fact that you had removed the odor.Here are some more tips:http://www.thekitchn.com/5-tips-for-getting-rid-of...

In those price ranges many companies just replace carpet,paint, some siding etc. and call it (newly rehabbed) to resale to an investor.Problem is that 200 a month cash flow you are banking on with just one roof replacement, plumbing being replaced, knob and tube wiring,lead based paint, heating and air going out, water heater,etc. can wipe out years of positive cash flow.You are then left with a neutral to non-performing property cash flow wise in a marginal area.It's better generally to buy a property in a better area for instance that might be 75k or 100k.

The land must appreciate based on its location, the cash flow must be neutral or slightly positive.

But because this happens at the same time, it is hard to see the property would have appreciated even more if not for the wear-down, and therefore the depreciation is just neutral.
