I will warn you that the beach mentality is very different than the metro area.

The problem with helping make the mortgage payments is that any equity created would be in their estate and potentially subject to claims of medicaid liens should they have health issues later in life and eventually need to move into a nursing home.  

There are a lot of deals there for flipping as well.If I were you I'd try and adopt an abundance mentality rather than a scarcity mentality. 1) You can find deals anywhere, 2) Competition isn't a negative thing...

They called us back 3 months later and accepted our offer of $50,000, because they became very motivated due to some family health issues and an ailing grandmother, who owns the home.

In 8 years for example, you might need to replace a water heater on each, so you should mentally be putting aside $125 each year in capex expenses for replacing a $1000 water heater (example cost) and $x/ remaining years left for HVAC replacement for example etc. so your ultimate cashflow might be 1000 less than the 6000 annual cashflow you get. 5000 annually is pretty good however.

But as I am a landlord, of course I am worried about tenant's health while they live in my property especially if there is mold/mildrew.

Everyone does not have the mental capacity, the tenacity, patience or persistence.

You also must not think like a "Homeowner" where Money Sources are concerned, or us a "stock/bond" investment mentality/action where investing is concerned.  

I hope to be able to contribute in a similar productive way in the future.Currently, I work full-time in health care.  

Auburn has Sutter and it is a short commute to Kaiser, Sutter, or Adventist Health in Roseville.
