Pretty,  as others have stated here, the permitting process through the City of Cape Coral has been hindered by their ability to scale up their staff to handle the massive demands for all permitting including new construction but also anything else that requires a permit, home improvements, sea walls, alternative sea walls, pools and more.From your post, I can see that you are frustrated, and I believe some of that is due to not understanding the steps and processes of new construction, including what must be done prior to submitting permits.

Alternatively, restructure the loan with equity participation for potential capital gains treatment at lower rates.

Hopefully helpful as you start looking around the market, as the only other alternative is to buy cash!

Alternatively, your brother could buy your share, which would result in capital gains tax for you on the difference between your share's original cost and its current value.

If, through the process of renovating the property, the market shifts, do you have an alternate plan for the property, whether it be to live in it until the market improves, or convert it to a rental property, etc. 

However, when I am unable to run screening reports due to this, we can push them to our "alternate screening".

Alternatively, you would need to drop your rents by $500 or more to have the same impact on your cashflow and your value.

As you're looking at properties it's best to identify multiple potential replacement properties to give you more opportunities and alternatives.
