I think there are some details missing here.

I tried to address her emotional fears with numbers.

It is time consuming, but I base the interaction off how much detail they put into their listings.  

I did a quick search, and found some people who said they had borrowed against their TSP for real estate investing purposes, but I was wondering if I could pool the hive mind for some more details on the process.When borrowing from the TSP do you arrange it through the TSP or is it a 3rd party lender with the TSP as collateral?

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

https://www.biggerpockets.com/renewsblog/the-truth-about-finding-a-mentor/here is a GREAT BP article addressing exactly what you need ;)

If you want more details DM me. 

I found THIS POST by @Andrew Postell which I believe addresses the exact scenario I had posted above.  

I'm also a fan of get the deal first figure out the details later.
