@Chris StrausbaughWhat state as in many states a lost note can still take action - especially non judicial states

I'd happily accept the former, though the 16% YOY property tax increase would be a non-starter for me.

It is a older non rehab property but things are straight and roof, plumbing, electrical are all in good working order.

I know property managers in every state who use non-refundable application fees and it is the standard for every class of property and applicant.

One of our local real estate experts is a big fan of Lee Arnold an his system.

They probably want to be certain YOU are legit.Most of the scams I've seen are by non-owners. 

It's a winning combination of direct access to industry experts coupled with building lasting relationships and get direct feedback on your strategies in small-group format.

There are bridge & DSCR lenders that can finance a non-warrantable condo.

I am no expert by any means but I thought I would drop my opinion here. 1) Should I focus on duplex since they're most likely less expensive in my area in category A or B properties, or aim for more units?

I make no claim at being a tax lien expert, but most of the time anything that makes it to OTC is so picked over it is nothing you want or could get much if any value out of if you had to foreclose.
