Advice: RE line of credit for newbie

[James Sanders]

Hi,

I'm hoping for advice on financing. 

I have a documented business plan for investing in new build SFR in some specific areas of Los Angeles. I have $2M in liquid assets (bonds and equities) a steady job of $200K income and a business partner who has about the same in assets but his salaried income is around $1.5M annually. Neither of us are experienced RE investors or builders but both have strong management experience with reputable companies.

I believe a line of credit is the way to go for financing. I'm not bothering with hard money as it's too expensive. 

I've been talking to big banks (JP Morgan, HSBC, etc.) that will provide a secured line of credit at a rate of $1 to $1 security (if I put $1M into an account with them, they'll give me a $1M line of credit at a low interest rate) but the assets need to be in accounts with their bank. 

However, I'm looking for a $2 to $1 security ratio so I can put in $1M and get a line of $2M. I'm happy to use my liquid assets as security (possible through a lien) but I don't want to sell these assets or move them to the lending bank (e.g., HSBC). 

Is what I'm looking for realistic? Does it exist for someone who is just starting?

Thanks!
