Lowest interest rate for a buy and hold

[Tony Fulco]

Hello - I am pretty new to the site but have really learned a lot.  I have flipped a few houses but am now looking for a one to four unit investment for cash flow.  Any suggestions on where to solicit the lowest possible interest rate for a loan?  House-crashing is not an ideal option for me.  I am in Maryland and would love to borrow at less than 10% down.  Thoughts?  Thanks.
