Is there a funky property tax issue that arises with the collateral that is a local municipality error and can lender quickly analyze the situation, assess and articulate the risk and allow draws to carry on or will they make the life of the borrower miserable?

Start small, network with other investors, and use tools like BiggerPockets calculators to analyze deals effectively.
