For subject-to transactions, the POA won't get around the "due on sale" clause, but it will help you do very important things like cash escrow refund checks and insurance claim checks, and other borrower-centric activities.

It will take some time for you to learn all you need to know and to save the needed cash to proceed.

The whole idea is to create pain for you if you don't proceed.

Prop tax, insurance, and MI are per loan officer and confirmed by my own research.

If you can't, just proceed without them until you find a great one.In short, I think you have 'analysis paralysis' and think you should just start.Actually... now that I said that I do have to criticize your list a bit.First, as someone said earlier, establish what your goals are.Second, pick a market.

Use all of the cash proceeds  ($160K ish).
