I would pull the 500K, to then monetize through yielded interest bearing markets, then pledge those yields to acquire the purchase power for the planned various down payments  

I have quite a few STR's that were decimated by flood/storm surge with Helene, and then Milton came to finish the job with wind.

I have two primary investor-partnerships thus the buy power is doubled as major projects come from 2 sources.

I just still need power. 

If you make the membership of this entity the members of the other 2 LLCs then you've also probably simplified and defined decision making power as well. 

Yes you take a pay cut but your purchasing power increases. 

Being selective about when and how you respond is often more powerful than addressing every single critique.

This project demonstrated the power of smart improvements and teamwork, delivering a strong return on investment.

This is fairly standard in the Westchester area given most homes are 100+ years old and the building code / inspectors didn't really come to power until the 70s or 80s.Likely your real estate agent will note the issues. 

Using the Whole Life Policy (or Indexed Universal Life) is very powerful.
