The ironic part is I have to BORROW $ from my retirement account now so I can begin to really invest in RE and grow tax-free passive income. 

If you have old galvanized and cast iron piping, old knob and tube wiring, old boiler system or a foundation that is failing, then run away.

We would have had a "proper" ring highway and the area by Highway 93 would have had much more development similar to what happened by the Northwest Parkway near the Flat Irons.  

I became interested in Self Storage and started researching that asset class. 3 weeks later my parents tell me they want to sell their storage units, ironically.

Ironically, the property manager and the insurance carrier are not included in the lawsuit.

It's ironic how I wouldn't waste any $ on pull-tabs because a 1-in-28 odd's seems idiotic to shoot for but a 1-in-100/200/500 "what if" is something that bugs at me as a real potential and concern. 

Kinda reminds me of that grant cardon character, though swarmy seems less flamboyant (and consequently less ironic.)It's not just about the cash flow you can get today, it's also about long term security.

The drain cleaner snakes or jets the line and rarely are they able to see the items flowing past.Also in some cases it's a combination, it could be an old cast iron pipe with a rough inside surface full of rust, which started to act like velcro to things that flows past, or a slight settlement causing a belly, which again impedes the flow, then the tenant pours down grease, pasta and bean, well, you get the idea.Most of the time you end up eating the cost especially if the plumber can't tell you anything.Now, you mentioned that the clog caused water to back up to a vacant unit next door. 

I am slightly concerned about the age of the house and what lies under all the sheet rock (possibly cast iron plumbing, old electrical, etc...) and don't want to be held responsible for someones child dying due to my neglect of DD and the house burning down.

Currently here in Western Australia we are in the middle of a crash in iron ore prices.
