I'm a local agent and the most important thing for us was the proximity to the Cape Fear Medical Center.

That 30k is a down-payment and portion of rehab on my next property without touching my emergency fund and additional cushion I keep.Hope that helps, I am new to BP forums and noticed you were in a similar situation as what I am going through right now.Also my logic when deciding if I want to sell is.

We also are the largest medical hub between DFW and Phoenix and have an incredibly strong agricultural base. 

If you needed surgery, you would not start medical school.

Only thing you should think about would be a large enough emergency fund to cover 2 monthly mortgages plus any repairs, etc. for 3 homes.

Advertise where the potential tenants you want hang out.In addition, does your area have military you could connect with or traveling medical professionals.

Credit score over 600 but that can be a misleading metric, people could have had medical issues that the bills were late and that might not make them bad tenants.

I also have around 25k in my emergency fund in cash.

Yes, if you are found to be negligent in your medical profession, and your malpractice insurance is insufficient to cover the entire judgement, then your assets will be exposed.

To mitigate risk lots of work is upfront ensuring you are aware of all the expected expenses like repairs, capex, vacancy, etc. in addition to having an emergency fund.
