Hats off to you that you have found properties that are mapped into the high risk but shouldn't be, on the flip side I see many properties that should be in high-risk flood zones but are mapped out because of political pressures (most of Houston, most of Sacramento, most of Virginia Beach, and New Orleans), if you are buying properties in these areas really consider the risk whether or not the requirement because property is in a high-risk flood zone.

Unfortunately they can’t break through it with water pressure or the snake.

We've had the same tenants in there for 5 years, they pay on time and take good care of the place (they planted flower beds, had a fence built and rented a pressure washer to clean the exterior, with our permission of course).  

I'm in Orlando and wanted to gauge what cashflow and CoC others are getting/finding in the area.

So, if you are starting a meetup, I think it is important that folks coming to your Meetup don't pressure to buy plumbing services or that this is another big boys club where newbies aren't really welcomed. 

The home is uninsured and property disclosure states a failed pressure plumbing test and noting repairs that include plumbing, foundation, and wood rot (very vague/no specifics).

And I wouldn’t want the pressure of putting all those asses in all those seats.

At the very least you need to gauge if your rehab estimates match up with reality (they could be better or worse) and if what you think your can get for rent matches up with post-rehab reality (again, it could be better or worse).  

This will take the "pressure" off you and also allow you to run things on auto-pilot.

The bona fide purchaser for value is a "new" wholesaler who just might cave under the pressure and screw everything up for everybody including OP.
