How do I secure a line of credit for new construction

[Malico Watson]

I am a real estate broker in Florida and in Wisconsin and I own a construction company in Wisconsin and I am interested in building new homes and selling them. I have a buddy that is in mortgage but unfortunately we are not able to secure deals with his company because most buyers have better financing or cash options and this is taking me out of the game. I am looking for away to get a line of credit that would allow me to lock in more deals. I don't own a home and my credit is about 650-700 depending on where we are with current construction projects that force me to use more credit.
