In my day when I did this we called those hypothecations.. and our bank would routinely loan 50% of our UPB.. and the hypothecation was done through the collateral assignment to the bank.and then when we moved into HML we have nice size credit lines for this we made a new origination and the bank took the collateral assignment as to 56% of ARV or appraisal.. that's how most of us HML did it pre 08.it was great we borrowed from the bank at 6 or so and lent out at 15 to 20 and made the delta..you get big enough lines and its pretty cool business. 

If I let it go and get foreclosed on it, will that affect my personal credit ?
