@Revis Boyd Isbell IIISpray the walls with TSP solution a few times, allowing the former coat to soak in before spraying a new one.

Maybe you are so close to the forest that you can't see the trees. 

Buying with positive cash flow is always the best solution. 

I can't speak to maintenance management or anything else like that but now that I've had a PM with a cloud solution that has an owner portal, I don't think I'd want to go back.

That may be a better solution.

They often times can offer better rates for properties that have never flooded before and that are in the lender required flood zone (A or V) if the property is in a nonlender required flood zone map (usually an X flood zone) then the government NFIP would be a better solution for you because they subsidize these properties and considering there is a high chance that any given building could be at risk take advantage of this option. 

Real estate investing is a bit like planting trees. 

Would this apply to a property that has a yard that needs to be cleared meaning cutting down over grown trees or only for structural?

So basically my answer is to put in place a system that will outsource the solution to the problem rather than trying to solve it yourself.  

This process is ridiculous, please tell me what solutions have worked best for you and how to get started.
