Does that mean it's on a roll and will go a lot higher or is it likely to do what it always does and correct?

One time, I sent a letter to an heir in Austin, and thier family ended up selling me a property they couldn’t maintain.

This allows you to invest in another property while maintaining the asset.Alternatively, a 1031 exchange lets you defer capital gains taxes by reinvesting in higher-yielding or diversified properties. 1031 has limitations.

All are on separate 800 square foot floors, with front and back door egress, well maintained and gut renovations were completed in 2019.      

Not for investment correct? 

I've read everywhere that they do not.Can someone explain which one is the correct choice and if any extra taxes are involved if they need to be on the LLC?

I want to make the best decision while honoring my agreements and maintaining professional integrity in this deal.

Chris is correct.  

Even then, you can expect they won't be able to maintain the home to the same level you did while living in it.

A nice 3 bed 1 bath around 1200 sq ft is easy to buy, cost very little to maintain, rents easy, and is easy to sell to another investor or a homeowner.
