If you are looking to borrow against your primary home and not urgently looking to close fast a credit union or regional bank are almost always going to be better rate then a secondary market lender. The CU and reginal banks use it as a loss leader to open checking accounts and the cross marketing opportunities. That is all the good, the bad is that 60 day close is not out of the ordinary.
If you are looking to borrow against second home or investment properties those same CU and banks simply do not offer in most cases. or, if you need to close quickly (like to buy another property) then a secondary market product is going to be the best. We close seconds on investment properties in 3 or 4 days often. But, I still refer promary homes with no urgent need to regional banks as the rate will simply be better.
