It's a great source.

Also fwiw source of income is a protected class.

Cap rate, cash-on-cash, NPV, equity multiple, IRR...Can anyone recommend a good source of information on using these rates of return when underwriting deals? 

The attorney review period was entirely foreign. 

I tried to search for online sources but not so lucky to find one.

Yes, definitely ask for bank statements to confirm the rent payments from the same source each month for the amount of time they have been renting.

@Lewis AndersonThere are a number if provisions that may be available to you such as foreign earned income exclusion and foreign housing exclusion.

I've heard from some of my sources that the owner made renovations to the condo and those costs may be attached to the property.I basically DO NOT want to get burned with this purchase so I'm trying to find out as much information as I possibly can BEFORE bidding at the auction. 

DON'T GO OVER IT FOR ANY REASON.Now calculate what your max offer is based on the terms you get from the lending source you're working with. 

A lot of deals can be created off MLS listings, but I would recommend including a different source for your leads.
