I have been offering for many months to try to assist him to avoid foreclosure but his pride would not allow him to take action.House is located in Cerritos CATotal debt including mortgage, HELOC, etc is 839k House ARV 880K  Rehab estimatess 100k+Father is 62 years old with multiple medical ailments, no retirement, savings, house is distressed.Now with a notice of trustees sale given, he may finally be open to a short sale deal on his house.

He said that a 100 year old house is like a 100 year old person that needs medical care more than a 25 year old person.

I’m curious if anyone here rents to travel nurse or medical staff and if you would recommend it?

With MTR there are places where you can market to traveling nurses and medical professionals who are looking for something furnished for 1-6 months.
