He also constantly blocking in the other tenant by parking in the driveway despite signs saying not to do so.He has a tendency to urinate on the property (by his moms door steps) and comes in and out during odd hours around midnight.

I recently discovered BP and am in a market with no inventory so I decided to look at a particular run down block I am familiar with in my city that has various multi family properties on it. 

Blocked condensate pan, dirty air filters, clogged pump, low freon, unit dying, vents not properly installed, air conditioning unit too small for square footage/airspace, exhaust blocked by plant material or stuff stored, animal inside the unit?

Some of KC is driven by neighborhoods and it is different block by block.

You want to make sure the line isn’t cracked, blocked or decaying.Your Lender will likely require a termite inspection, or at least they do here in most cases, so ask your Lender or Realtor.By tank sweep, I assume you mean septic inspection?

Our rental market is tight and we have (much) nicer than average rentals that are priced near the top of each "market" (within a couple blocks) where we compete.

If you know what you are doing, and have been around the block a few times, then you might be fine to offer on and purchase the property without going through an agent. 

Another option if you are wanting to be nice is to get those roll-up blinds that can block the sun.

IT WAS A FULL RENOVATION THE ONLY THING WE KEPT WAS THE OUTSIDE BLOCK WALLS OF THE PROPERTY.
