Yes, Cook county is definitely on the hunt for every penny they can get their hands on.

I lived in Singapore and Korea for a little while when I was in oil and gas industry.

Or do you mean that: " If the tenants put a bunch of oil/dirt/etc on the walls it will easily will wash out?".

You also need to think about how the tenant in the basement will cook.

If she's willing to raise it to $950 start there-you have to live with your wife and I'm betting she's the one who cooks your food. 

Anyone who tells you something is "bullet proof" is trying to sell you snake oil.

@Daijamonet Cook I love this question!

If you go to the add on route(add a bedroom and a bathroom), you can think about the add on functioning like an attached “in law unit” with a hot plate for working professional to cook on, with that I would say rents about 900ish depending on the set up.

@Joe Splitrock - hmm, but what if he just had a community kitchen, and the residents decided to hire someone to cook for them?

If you know how to build better mousetraps, build mousetraps, if you know how to trade bonds, trade bonds, or stocks, or oil, or rare earth minerals, but I think for the average American, the best way to get wealthy is to invest in real estate.
