In 2.5 to 3 years, I believe I will be able to make a $75-$80K “profit” upon selling. This presupposes I will finish the rest of my needed repairs and does not include a co-broke fee. That’s not zero appreciation. And I daresay I very likely don’t have the carrying costs that you do, lol!
From your posts, it sounds as if you have already removed a substantial portion of your equity.
You still haven’t told us if all that “40% appreciation on paper” will be YOURS or if you have to split it with a co-owner upon sale!
