I have some cash saved up but would rather keep that as an emergency fund.

Make sure you have a very plump emergency fund so you can cover all of your mortgages and any repairs / CAPEX for a few months in case all of your properties go vacant and fall apart and it takes several months to repair and get them rented. 

They fill out a lease which doesn't have any personal info, just the agreement, their signature, and their emergency contact.  

should an issue or emergency arise - they're never convenient. 

Brian Adams maybe I should've prefaced it with most of my friends work in emergency medicine so their advice may be jaded.

So I lost $25,000 on the sale, $45,000 i paid in insurance, 39,000 in property taxes, $16,000 in emergency repairs, and $6,000 in a special municipal “assessment”.

I dont want to get the cart ahead of the horse, but here in Colorado tiny homes are emerging to be highly talked about...even among the investor community Im in touch with

Name, age, ssn, phone, email, length of time they have lived there, prior address, how long at the last address, employer, job title, income, how long at that employer, other source of income, and emergency contact.

In the ideal case, there be a "new California" emerging somewhere in the next 10 years.
