Are you working for a firm in southern California or do you have your own practice?  

But, is this practical for you and your team if you have 50 properties?

Kind of out in the middle of nowhere, but my son just started college at Tarelton and we live in CA, so its on my radar now...university has plans for big growth in the next 5-10 years. 

Understand you are doing reviews in various forums and posts to help people with your reviews of their businesses.My roommate right after college in Houston. 

I would suggest watching some youtube videos, come up with your own variation of someone elses script and practice it until it sounds natural.

No college , no 5 years of experience needed .

Are there any particular management practices or tools that have proven effective for rent-by-the-room setups?

If you really want an answer you can confidently rely on you'll need to engage an attorney practicing in the state the property is located in and the state of residence of your grandparents and have him research the specific facts of the case.  

I'm looking for insights and best practices from fellow lenders and financial professionals on how to effectively manage borrower relationships.
