If people are low on credit scores or a little more risk and you want to rent to them, I would sugget having them do a co-signer or putting up another months rent. 

I think what you're referring to is a CO/ALR device.See this: http://www.alwirerepair.com/serv02.htmNever used one myself.

You could always get a cheap plan at a co-working place like WeWork.

Hi @Steve Krause -  I manage Airbnbs in the Charlotte & surrounding areas and would be happy to connect if you are still in need of a co-host / property manager. 

Is he willing, assuming qualification, to be a co-borrower/co-signer/co-owner on whatever you buy?

The seasoning requirement does not apply for the following cash-out refinance transactions: Loan proceeds to buy out the equity of a co-owner for an owner-occupied primary residence special purpose cash-out refinance transaction: When property has been jointly owned for 12 months prior to initial loan application; unless parties have inherited or was legally awarded the mortgage premises.

One couple still has income coming in from their Russian business and has an American family friend as a co-signer.

My lender suggested getting a co-signer, but that would only work for the 1st property, right? 

Otherwise, they are required to complete Fannie Mae's 1038a worksheet (you can google Fannie Mae rental income worksheet and download a copy if you want to run the #'s yourself).Aside from starting a new job an alternative might be finding a co-signer. 

As a beginner, you can learn a lot from your uncle with a few rentals in another state or a co-worker that's on their second house hack.
