I have now replaced my old corporate job income and expect to make over $70k cashflow off of my 31 unit portfolio while also having the time I want to be able to enjoy sailing, camping, hiking, and hunting.

The solar system adds no value to my property for rental purposes, and I may even be ripping up the roof & replacing it in the new year.Beyond sending a nasty letter through my attorney via certified mail, demanding the company come pick up their equipment, am I required to take any further action or fulfill any obligations regarding these contracts?

Your renters will destroy these items and want you to replace them. 

•Systems: Servicing the HVAC system, replacing the water heater, and updating the electrical panel.The renovation was completed in 13 weeks and totaled approximately $35,600.

My current tenant has removed a picture from the wall and replaced the provided bedding with their own belongings. 

Fixing a leaky toilet, replacing a broken light fixture, etc. can create good will.

Try to pick things where replacement pieces are possible and easy. i ill add that I put in some games we really like as a family, they went missing over a couple of months.

@Angelica CrawfordHere's a very helpful article about replacing the value of the debt: https://www.ipx1031.com/replacing-debt-in-a-1031-exchange/

That's not exactly an up and coming area -- I'd research who built them - can likely find that by going to the SG County Recorded Docs site or by seeing who pulled the permits during const -- Wichita has been on a duplex building boom -- look at the tax value -- They probably have that or less in it on the build - I also doubt they were built to be quality long term -- things such as the trim/cabinets etc -- they all look like the cheapest stuff a guy could buy - if the cabinets aren't oak and there is MDF or pine trim and pre-hung doors with engineered wood jams I'd run.  2-3 yrs ago for $180k -205 or so you could buy duplexes in Maize, Kechi, Valley center all day to builders that were selling them off to investors - not worth that in that area.

Definitely get the structural engineer to look at the joists & support beams to see what's up with the uneven floors.
