a couple of years.)

Sounds like you need to have a relationship with a couple of good contractors, 40k for vinyl siding sounds high, what was the material cost.  

I'm a digital nomad who purchased a 4plex in Carson City, NV a couple of years ago as a buy & hold.

In the last couple months, the zoning has changed for my home, and the lot is now classified as RM1 (low-density multifamily), and I have learned that I can build 3+ units, and don't need to include any off street parking. 

@Ryan Johnston A couple of questions worth asking..

Since this situation was so egregious (IMO), I would either boot them out now, or at least have a serious talk, real serious....If you're going to let them stay I would just get a really deep cleaning done, maybe a couple, and then replace carpet after they're gone.

It also requires different reporting of that separate interest expense on the K-1 each year so the partners know they have the obligation of tracing that interest expense to however the partner used the distributed proceeds.I typed all this up and realized Mr Brooks has left the building and posted this 6 months ago, but hopefully someone else will find this useful!

I also hold a couple of real estate forums in the area for people like yourselves to connect with service providers, GC's, etc. 

Once all the work was done we rented the home for a couple years and then sold.

Then I put about $45,000 in fixing it up and I expect the appraisal to come back within the next couple of days at $240,000 or higher.
