In the addendum, I would add things like no smoking, no treadmills, etc.

Do you smoke?

If it's light tones, people will think, some dark maroon on this wall would be a good contrast to the dark green we'll put on that wall and so forth.

Anything that constitutes a major inconvenience to the tenant, such that a reasonable court would find one negligent for not addressing quickly, constitutes an urgent maintenance need.Example of the former: leaking water, gas, exposed live electrical wires, smoking in electrical panel, dangerous leaning tree, etc.Example of the latter: poor heat performance of heating system; clogged gutters overflowing causing basement dampness; etc. 

The value of the properties location I think is really important, Think of a long street that ends in a dead-end cul-de-sacThe beginning of the street is a really busy intersection, so the really busy intersection has less value than the end of the street cul de sacYou may want to talk to an appraiser that does this for a living and ask them how different parts of the neighborhood can seriously affect resaleI always ask myself when I'm looking at a house from a buyer's perspective, can grandma walk around the block at 8 o'clock at night just before dark?

I bought an REO condo in Logan Square, fixed up some cosmetic stuff (who in their right mind paints a living room dark brown?)

Chances are you will not get caught, but I have seen firsthand neighbors call police and code enforcement officials when the vacationers were smoking pot, being loud, etc.  

I happened to have the criteria of no previous evictions as well as no smoking and no drugs. 

There should be hard-wired smoke/fire alarms in all units and common areas.

Why do you not allow outdoor smoking?
