A good old stock market collapse and a recession are welcomed, but it may take time to see the results.

I took a 3 / 1 that the floor joists were collapsing and turned it into a very nice 3 / 2.

The Soviet State collapse  "peace dividend" for me equaled a shrinking of military procurement contracts which tanked the SoCal real estate market and caused a brain drain exodus that carried over to the rental market.

The market collapsing as mortgage backed securities were being defaulted on left right and sideways...  

Down the line I will have collapse all properties into one account and keep the security deposits separate.

If the property is older, then there may be roots in the sewer line, or collapse of the line feeding off the property.

I have a high-stress job and need to create other streams of income asap before I burn out and collapse in a blaze of exhaustion and defeat... that is all ;) 

People were saying the exact same thing, how can anyone make any $ with prices collapsing.

The real money came when we sold that property six years later for double what we paid for it, and we were able to pay cash for foreclosures from banks that were going out of business in the big collapse.

In my experience, you need to be conservative when investing because everything increases (insurance, real estate taxes, etc.) and you could also have surprises (roof needs replacement, floor is collapsing, etc.).
