I do a temp wire hook up and flush the iron down the drive for 15 minutes then put it back together .  

I'm not a particular fan of that Bruce Willis move where they go on the Asteroid to drill and blow it up, but I saw it recently, and when they're busting drill heads trying to get through some iron in the crust of the asteroid, "bad-***" Bruce Willis reassures his crew:"Bad-***" Bruce: "We'll be fine.

It's ironic that @Dmitriy Fomichenko mentioned Dave Van Horn because I know that he has ties to Bawldguy.

The master suite should be awesome with an office space,You might think of having  a swimming pool, a nice court yard and bbq area, definitely provide a well defined entertainment area inside and outside, perhaps a spa with a bar area, redwood decks even a tennis court but you can take that as an option.

The cast iron sewer lines in those Tempe homes from the 50's can be a real nightmare. 

I found it ironic that at the end of the article there was an ad for a website that teaches how to flip houses.

Thank you, Chris Mason Ironically, the same lender had just completed a refinance on another property (it was #5...).

Ironically, I already knew this from past business experience, but again, my assumptions got in the way.

Yeah, I do with less of moving old cast-iron bathtubs around. 

My point was that if you intend to create massive wealth and do so with out the difficult efforts of finding 100+ individual doors, and also do so from a passive or semi passive standpoint, then multifamily would be the best choice in my opinion (or something similar like other commercial class buildings).Thanks for your comments David, I think we are the on the same page and your last comment allowed me to respond with more details.Yep agreed ... guess where I vary from most is that I have no desire for "massive wealth" as you have it defined and definitely have no desire for the risks and persistent PIA it would take to get and stay there, though I'm still fairly young and ironically I may ultimately get their by accident by re-investing my "reasonable margin" on excess passive income over time ... no matter your income ($20k/mo or $100k+/mo, passive or otherwise), if your margin over expenses is continuously zero or negative you are not wealthy nor will you ever be ... if it takes a majority of your time (your most valuable asset) to create that income and the income will stop the second your effort stops, then you equally are also not wealthy IMO.
