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. 

Fix the issues but they do not have the right to withhold rent until things are fixed. 

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.

My parents are looking to move, and are willing to sell me the house.

Is there any parents out here that can give some tips on how to stay focus to progress to your goals?

I want to start in whole sale real estate, I know what it is and I know a little bit about it, but I need a mentor, I told my parents about it too, they said I need to look for one.
