The Mortgagee has a superior interest in the rents already.

theoretically any overage at the sale - in excess of superior liens, taxes, legal costs, back interest, renewal fees, and any other expenses paid by superior lienholder would go to holder of inferior lien.

I remember the day a Superior Court judge sold me a house Sub2.I guess I should have kept the crap to myself...

Subordination is where an existing lien holder agrees to allow another lien holder to have a superior position in the order of the liens filed, so now the bank has a first, and after subordination, a second position with the new loan and the seller is now in third position.As stated above, banks rely on the appraisal to establish their value of collateral.

In my experience, the MLS (in Houston anyway) is far superior to any other info online.

From there I can see if they are true comps, or adjust up or down based on if they are inferior or superior.

There is no mathematical superior place to sell the loan in regards to seasoning of term.
