As I understand, I'm still responsible for paying condominium fees and property taxes, which is becoming a significant burden for my household.I'm exploring options to recoup at least half of the property's value, considering it's currently uninhabitable.

Tons, and I do all the time.

@James McGovern The fact that it takes a lot of time to put together and then to produce to share.

My landlord stuck me with an early termination that amounted to about half of the cash that I had on hand.

So as long as you know you have 25 to 30% of the proposed deal in cash.. thats one.two do you have experience.. these are tough to get for first time borrower. ??

You could do all of this at half my age. 

I want to be a full time investor in real state and being an architect really helps in the rehab process How did you find this deal and how did you negotiate it?

(I own 150+ homes) It's the water running down the exterior walls that does the most damage over time.  

The time frames are tight.

You didn't mention the time frame but if that opportunity was a few years ago they had upward pricing pressure (hence $200k high sales price) and lower interest rates bringing in more offers.
