Ask any commercial real estate agent, as they tend to have more situations like this, they do not send an NCND, they send a co-op broker agreement and both brokers sign.

Would I need a co-borrower or co-signer?

Have you considered a co signer or to just make the 2 other tenants jointly liable for the other?

@Julio Puentes, could it be turned into a co-working space? 

Has anyone here rented to someone who has a co-signer located outside of the U.S.?

@Jason Farr makes a good point about a co-signer that will help you be creative,However, if really want to qualify on your own then look at a couple things:Are filing your schedule C with the IRS?

As far as finding a loan that a 19 year old college student will qualify for- you pretty much need a cash loan from family/private lender or you need a co signer who has income history and decent credit.

George, I though about your idea and in fact, I spoke this morning to RE investigator from the MN Department of Commerce and I asked him if I could pay anything to anybody that finds a vacant property for me and he said that $ only could be paid to a licensed RE agent and not to a Co or an individual. 

It is a written agreement between you and the other wholesaler how the compensation should be split (50/50 or any other agreeable terms.)You can write up a co-wholesaling agreement for each property, or just as a general.

You can always add a co-signor who is a non occupant borrowers but if you go to 3-4 units you will need min 25% down payment or equity (if refi).
