financing to rehab REO for personal use

Seriously considering purchasing an REO property for our primary residence, problem is it needs a lot of work. I am already pre-authorized at my primary bank for mortgage considerably higher, but they are telling me I would have to wait 3-6 months to apply for equity or construction loan (and clearly no guarantees we would get it). We would need work done before moving in. How can I get a loan that would include money for the work or a 2nd loan to cover those costs? I believe price is too high for FHA 203 rehab loan. We have good credit and up to 20% down payment. Any suggestions on who might do this type of loan. Need something soon, so we don't miss our opportunity. I'm in CA if that makes a difference.

Thanks for the help.
