We plan to keep most of our portfolio in Knoxville.

We plan to move forward with the sale either way and I have recommended the mother to seek representation, but where I'm lost it, why would anyone, prefer and eviction over Cash for Keys?

More specifically  the matter in which you operate your real estate business on a daily basis/ contractual relationships and your insurance coverage. 

Interest rate buy-downs are available for refinances and HELOCs.Below is an example showing the benefit of the right interest rate buy down.The challenge is that we cannot choose the final lender upfront because buy-down options vary almost daily.

I think I need to submit a floor plan as well with application for occupancy?

There are far more important items you should be prioritizing but first so I am clear on the strategy, it sounds like the business plan is to go under contract, renovate the building and then purchase the building once renovated and stabilized?

You absolutely don't need your own license, and I personally wouldn't recommend getting one unless you plan on doing it full-time (just my opinion).

Fourth, create a long-term real estate investment plan that complements your preferred lifestyle and financial objectives.

(I’m planning on doing a 1031 exchange) 

Picture this: After weeks of negotiations and planning, all parties involved finally reach an agreement on the terms and conditions of the sale.
