Like Ronald said, make sure your cap is good too, if not use Portland cement with an acryl 60 additive mixed in with it. 

Blinds don't work, horizontal or vertical.Draps get wet.Putting a layer of tint or reflective materials on the glass help some...as long as you don't turn the lights on.Is there any sort of high tech materials you can put on that are like the one way mirror in the police interrogation room? 

If that doesn't work, take a dose of @Rob K 's advice and mix it with a dose of @Ryan Richard 's advice - let an undesirable occupant move in for a few days.

Call the last landlord and ask how much the rent was and if the tenant had any problems paying their share (if rent exceeded their voucher).I have mixed feelings about getting a tenant with a full-rent voucher.

Then figure out which strategy fits that why best.Chicago is a great place to invest because there are very clear cash flow markets, specific appreciation markets, and a mix of both in some neighborhoods.

@Kyle Calica, I would say that it's a mixed market, but overall I see flat rents, and some markets are still going up but slower.

Each LLC has its own bank accounts, separate accounting and you never want to mix personal with the business.

In fact, one "fast talking" HML kept changing and mixing terms, I had trouble getting the actual numbers!

Etc.I would assume the details on this vary from state to state (which also means you are likely to get some mixed up answers here).

I made that move about 3 years ago after working retail as an tech/intern/rph for 10 years and it was the best decision I've made professionally.
