They have a 2 year old and another on the way and I remember my parents being in the same boat when I was a kid.

I'm trying to get creative with financing as I'm just starting out and either way will need some help from my parents.

If you go off Airbnb get their parents to cosign and guarantee the lease.

Ironically, my parents live in Northern NJ.

Thanks for your reply, I'm using different accounts per business and do not commingle the funds.I think that leveraging the class/location feature in Quickbooks can be good enough to differentiate the accounting aspect of the three.Currently, I decided to setup the properties as customers, and the tenants as sub-customers of their respected property(=parent customer).

Renters that have an elderly parent or parents are great. 

Also, just thought of this, maybe he would co-sign a conventional loan since my parents house is almost paid off, they have much more than 20% equity. 

My thought was this: Could my fiance or I, (somebody outside ownership or affiliation with the business) create a property holding company that would purchase the home from her parents and lease it back to their business?

I have just purchased my wife's grand parents home (now deceased) in Lafayette Louisiana where my wife grew up.
