Good choice Chris and Good Luck.  

Both the local banks and FirstKey will lend based on ARV without regard to how much you spent (except that I don't think they'll let you borrow more than you actually spent).

I Portland you would not have those choice's... there are no banks that are going to lend long term and portfolio.. typical would be 20 due in 5  6 to 6.5%  with one point.

They have to do an appraisal and some other items which I believe the borrower pays for.

There is a lot of money available looking for deals from, solid borrowers. 

Save I have a choice of taking 100K in ROTH accounts vs 100K in a Traditional IRA.

I just want you to be sure you are fully prepared so that you don't end up regretting your choice.  

Most banks will not borrow on these.   

Listsource.com or any other list provider can get this information.Go to listsource.com, create a free account, then call their customer help line and they can walk you through exactly how to do it.This is a list you'll need to BUY.Free way is to search county tax records through MLS (see if you know a Realtor who will let you borrow their ID) or at the county court house for properties owned a long time- i.e. 20,25 years plus.
