@Jaron Walling I bought the property for 67K.

It all depends on the walls you are hitting.

Jaron Walling said something that caught my attention, "search for and buy a bad roof, leverage it during the negotiation"....especially of the property has been sitting on the market longer than normal for the current market, a "bad roof" might be a gift from the real estate genie.My point is this: get good at estimating and fixing a bad roof (or any particular problem found with most houses that sit on the market longer) and you'll get comfortable buying/fixing properties that scare off other buyers. 

When I subsequently asked the tenant over the phone how many cats she had she said four, which is likely half the number she actually has, but is still a lease violation.At this point I feel like it’s pointless to even ask if the cats are neutered (and therefore less likely to spray urine on walls) because clearly she is willing to lie to me and her attitude seems to be that she makes the rules not me or the lease.

As a result, we have significant water damage to the floor and rugs in that 2nd floor bathroom and a bedroom, plus there is even more significant damage to ceilings, walls, furniture, and rugs to 2 bedrooms on the first floor.Our initial goal is to dry as much water as possible with wet-vacs and dehumidifiers.

But if you do have a house that sits in expansive soils and are susceptible to shrinking and expanding they can put pressure on the basement walls (exacerbated by frost/thaw cycles) and cause them to crack horizontally.

Is the layout still good or are you moving lots of walls? 

My guys had to take the whole wall down and rerun everything.  1.5 days lost.
