Copy of drivers license ?  

The issue might be however that the appraisal value won't consider the ADU in value and your appraisal, the main driver for the ARV on the refi won't be as high.

You need to be the investor in the drivers seat not going along for the ride in the parents car. 

It was one of the primary drivers of the crash because people got into properties they weren't qualified for and didn't have equity and were left holding the bag when the market shifted.  

I'd still request a picture of their driver's license for address verification and call the landlord references on the report for additional info.

Where $1000/month is too much to cover for food, gas, utilities, 24 hour on-call house cleaner and personal assistant, plus a driver.

This entails going through the drive notes from the drivers that go to each property as well as talking about the numbers (estimated repair costs, fees, ARV, etc.).

I work as a delivery driver and half of my money is from tips, which dosen't count towards my income.

Real estate is just the investment vehicle, you are the driver and it is ultimately up to you to guide your investment. 

The biggest economic driver that interested me in this deal was the proximity to where the proposed light rail extension is planned to be located.
