I'm really looking forward to this challenge and hope to become self sufficient at some point, because at the age of 32, I've had my share of the corporate world and want to start living on my own terms.  

(Well...sort of) I want to learn, I want to make money - of course, but the options are vast and the leap is terrifying.

Jason is correct that the vast majority of Insurance companies will not insure a rented condo with a Homeowners form. 

“Backyard investigates how buildings could utilize sophisticated manufacturing techniques, smart-home technologies, and gains vast insight from the Airbnb community to thoughtfully respond to changing owner or occupant needs over time,” Gebbia says.

I would want to validate that the HOA is being sufficiently funded and there is not deferred maintenance or upcoming special assessments.

Don't forget to tell her about the self sufficiency rule which applies to 3 and 4 units with FHA. 75% of the total rents must cover the mortgage.

Specialty providers of such plans that focus not only on document provision but also the necessary consulting support you need to run your plan successfully are a vastly superior option for the Solo 401(k).A 401(k) is a trust. 

@Jason Wu, if the property is located in California, be aware that you may unintentionally cause a re-assessment of the property if you transfer/add yourself to title.If your partner is trustworthy, one option is to form an LLC with your partner (again probably California LLC if the property is in California), put this property and subsequent properties into the LLC, do proper accounting for each property in the LLC, obtain sufficient insurance, and operate your properties prudently and reasonably. 

Not having sufficient credit can negatively impact your score.

Once you've located a property,  is hiring a title attorney to search for liens sufficient to buy the propert?
