Just be careful of "nontraditional" lenders that will require a large up front fee.
Being a lender for almost 15 years, I have just about seen it all!
We have recently developed portfolio private lending programs that are helpful and specific for real estate investors.
There are still requirements and the loans still have to make sense however we can finance based on the "AFTER REPAIRED VALUE"
This can be very helpful if you have a property that is in need of a lot of work and your funds are limited.
If you decide you want details you are welcome to run your loan scenario by me sometime if needed. I talk about several of our portfolio loan programs on this Trulia blog http://www.trulia.com/blog/jason_wheeler/
I hope this helps you.
