On a DSCR refinance, you can hold title in an LLC, however a person will need to be on the loan (not an entity). 

Your name would not go on anything, just need someone to review and advise on best course(s) of action.Also, not sure if there are nuances with California but experience with that state would be a plus as a noticed this: https://www.ftb.ca.gov/file/personal/reporting-like-kind-exc...Thx!

One sale can be worth 10-20 leases or more, personally I would rather work really hard to sell a few properties if I was just getting started.

One person may take the “it adds perceived value”approach, while the other is cost conscious.  

I ended up expanding my personal credit by $8,000 on my own.

Constant housekeeping complaints, bookkeeping errors, them using my property for their personal gain without me knowing it, charging outrageous "fees" that they didn't share with me, which effectively lowered my rents, and questionable repairs and maintenance expenses and quality. 

There is a SFH my relative is selling at auction due to personal life circumstances.

I'm also a big believer that Health is indeed a person's greatest Wealth.

I have personally never been there but are there specific attractions, employers, military base, etc. then make Indy a good STR/MTR market?

I do not personally recommend these as an investment, but I can offer some insight to your questions!
