If I remember correctly, we had a chance to evict them in December 2023, right around Christmas and New Year's.

I think my line of thought is correct.2nd and very few investors realize this.. but lets say you have a wholesale deal and your buying it for 100k and the wholesalers contract is 50k and there is a 50k assignment fee..

To do that, to completely re-zone and re-plat the entire area would require, if my history is correct, the largest exercise of eminent domain in US history. 

Yes, you do.Here is how to think about it correctly. 

If I do a cash-out refi, it will change my interest rate, correct?    

One thing to add is that when you buy a new build, your PITI will likely not be factoring in the correct state tax number.

Our exchange didn't work out and they returned the proceeds via wire as soon as our 180 days were up.I not sure I am doing this correctly.

I wouldn’t think this would necessarily be the correct solution in a condo unit.

You are absolutely correct - I have never done this exercise. 

E.th. you mention in the post is correct.
