Mezzanine Funding, Second Position Lender, or JV Funding

[John C.]

I own 90 buildings in PA, 135 long term rentals and 4 short term rentals. I and am seeking to expand my short term rental portfolio. I have dscr lenders I work with, looking to purchase around 500k properties in Poconos, Jersey Shore or Englewood Florida. My challenge is coming up with the $150k or so deposit or closing costs per house to scale quickly. I've heard that Mezzanine Funding, Second Position Lender, and JV Funding are difficult to find. Can anyone help me out?
