About this time, my hubby's mom was diagnosed with cancer and our money went to trips to FL to see her instead of on rentals.

Got gazelle intense about saving for down payments.Stayed 10 years in the UK, and my MIL was diagnosed with terminal cancer.  

After diagnosing the issue, found out a piece of blade was broken from the fan causing it to spin out of balance and resulting in the vibration the Tenant was hearing.

Account Closed Bed Bugs are hard to diagnose, many don't know what they are.  

Service company goes over and diagnoses the unit, but doesnt call owner or Property manager about the results.

I was offered a similar opportunity a few years ago through a friend of a friend who was diagnosed with something that was going to prevent him from working and eventually cost him his life. 

Not to say a deal wouldn't fall in you lap, Jamila, but it is very unlikely, let alone you would need to engage an attorney to write the contract, be comfortable in your ability to diagnose high ticket items in a quick manner, likely pay all cash (which you mention not wanting or potentially being able to do), etc.  

Thumbs up.This approach works well for overflowing toilets, resetting circuit breakers, and remotely diagnosing lack of heat / lack of AC.

Is there a way to have the issue diagnosed and bid on by foundation companies? 

You will have to find a foundation repair company in your area to look it over and diagnose.
