Right now it is just her name on the deed.We thought about a transfer at death and for her to put it in the trust, but my MIL wants my wife to be a co-owner now.

Looks like i'll be able to set up a co-op pretty easily.

She paid 6 months up front and had a co-signer...  

They would have to go on the loan as a co-borrower.

Ive been told to get a co signer.

@Drew Fein - Would you like to weigh in on this being as though you are a CO based RE attorney?

If this is the direction you want to go, perhaps, see if you can find some folks that manage STRs and need some help, and perhaps you can take a co-hosting role to gain some experience first.  

Income criteria ensures that the rent is affordable for your tenant based on average household expenses.One way to get around income criteria (we use this with college students) is to get a co-signer who does meet the income criteria (and also passes a background/credit check).I would say that if your applicant can't get a co-signer who qualifies under all your criteria, you should deny the application.

If they don't have a good employment history, I require that they have a co-signer who does.

About 38 minutes into 560, Sam mentions a spreadsheet he uses for additional expenses when following a co-living strategy, that he would be "happy to share".
