I should have said in my initial post the seller purchased in May 2023 at 123K and did work on roof, HVAC and HWH and not much else from what I can tell.  

I would double my initial investment even after capital gains taxes.

This negative initial position can consume years of the cash flow.  

Exit at nearly double the initial purchase Lessons learned?

I initially thought may be a security alarm, but a security screen door seems much better solution.

Initial financing.

I used your list and found Penfed for this HELOC with an initial rate of 4.75%. 

Often they seem to sell in tougher neighborhoods because the initial numbers look the best there on paper.Generally I would look above Hwy 380 and maybe Sherman/Denison specifically, but there are other places too, depending on what your goals are. 

Exit at nearly double the initial purchase.

Initially intended as a long term hold How did you find this deal and how did you negotiate it?
