Corey Peterson also has a very easy to use template to get into the larger properties with some safety margins. 

As a safety measure before you can move those machines out of the unit (likely after your tenants leave) would be for an auto shut off valve - some of them are digital and will do it when they sense any sort of leaks. 

It's a matter of being patient, and then acting quickly when deals do come up.

You have to be patient with these opportunities as subdividing your lot takes time and capital, monetizing your lot(s) takes time while you’re paying taxes, maintaining it, etc.

not a bad safety buffer as well  

The most successful entrepreneurs are patient.

Just learn and be patient and keep looking, but looking doesn't have to be overpaying, it's just educating yourself.

I talked to a friend who is a nephrologist and he says it is very very rare that any dialysis center who is in business for more than 5 years would move because all the patients are in that community and majority of the patients are long term patients.

Some cities/insurers will have requirements like adding a safety gate around the pool.

Be patient - you will get there!
