As long as you stay under four units, you're not governed by the Fair Housing Act, which has some accessibility requirements.

While not in TN specifically, I have assisted clients do as you have described: live in a property as a principal residence for 2 years, rent it out for 3 years, then sell.Based on the situation described, you would appear to be eligible for the MFJ joint exclusion on principle residence on your 90% share.However, in order to retain that ability, the house will very likely need to be sold (ie, sale closed, not just under contract) by the end of this month. 

Willing to do preliminary visits to houses to take pictures, make rehab lists/scope of work, etc. 

We only have a tiny house as of now, but the infrastructure in place for a 5 bedroom dwelling.

The house is falling apart and is an eyesore for the community.

Hello, I am currently in the middle of renovating my first house hack/deal.

Hello, we are currently house hacking a duplex in Greenville, SC and have been using RentRedi as our management software to handle payments and leasing.

Specifically I see a solar system on the house but am wary because I do not know if it is a PPA or leased system... or owned for that matter. 

Been house hacking in the north shore.

High likelihood of low maintenance for at least the first 5 years, depend on the build quality of the house.
