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

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.  

Total Title Solutions is also fantastic and does mobile closes.  

@John W. refinance, save, or HELOC I know that sometimes having a property free and clear is a nice thing to have so if you can avoid leveraging it long term for your peace of mind that may be the right solution for you.

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. 

Solution: We move to Fells Point in Baltimore when our lease was up at the apartment we were living in. 

Best solution I've found is to try to stick to AMCs owned by the wholesale lender that I'm sourcing the loan to (& stick to lenders that have ownership interests in AMCs).

You are quick to bash my efforts but offer no real solution on how I can improve?

And 2, what possible affordable solutions can be taken to properly separate the units, so they are truly independent. 

However, I am trying to think for the long-term, and if I am to meet my goal of 20 properties in 10 years, I won't be able to use my own money to sustain this.
