I currently own a duplex with a garden unit(typical Chicago brick style) in Irving Park.  

They have a really cool indoor fish pond, too, you need to check out. 

There's not just taxes and repairs but also insurance, vacancy, water/gas/electric/internet, garden and maybe putting something aside for once-in-a-lifetime big overhauls (roof for example) every month. 

century 21 Castelli in Garden city.  

We were planning to do one ground floor and one garden unit for STR so similar to your guidance.

If things get REALLY bad, then yes, things like rationing, inability to water lawns/gardens, etc. may cause demand problems in those markets. 

It's only happened once, and that turned out to be a combination of three things: a toilet leak, a teenage daughter's long showers, and a lot of watering in the garden in a dry summer.

Large master suite, wood look floors, two closets (one being a large walk in), tile master bath with granite counter tops, linen closet, large garden tub, spacious walk in shower.

@Adam McLellan There are subdivisions with low HOA, but they have fewer amenities - cable, gardening, clubhouse, tennis courts, etc so you will have to pay those.

Or it was removed as part of the indoor hydroponic marijuana grow operation.
