I had to get the city attorneys involved to get a certified, notarized, recorded copy of the Release.

Multiplex if  numbers make sense why not? Are

You just need a "Release of Information" form, doesn't even need to be notarized just signed by the Seller/mortgagee then sent to the correct department at the bank.  

Pretty amazing cashflow when compared to the PNW market so I cannot comment if that is good or not. Are

Once both parties have come to a consensus go to a notary, sign the agreement, and notarize it.

@Amanda Williams1. secure the property by having SELLER sign and notarize a purchase and sale agreement for the property.

If not are there any creative ways to do this?

Do I need to have it notarized?

We have another form that a sub fills out and has notarized that they are an independent contractor.

@Donny Widjaja  since your being asked to just loan enough money to make payments on the existing first mortgage . you would simply be doing a unsecured Promissory note.Although not tagged to a property there is no defense for non payment and a judgement is easily gotten ... caveat is that this person actually has some assets which sounds like he probably does not since he needs to borrow from you to make payments .unsecured prom notes to a very qualified a borrower are fine.. second loans behind construction loans are not are not advisable in any scenario and can very well be a event of default on the first loan.
