lower sale price is obvious in general. The south loop is mostly newer construction so a W/D in unit is pretty standard amenity wise.
lower rental price too. less traffic in general for either sale or rent.
Now, if your unit has something that makes it awesome, you can offset the lack of in unit WD a bit.
How big is your unit? Is there laundry in the building at least?
Can one be installed in the unit? I need more to work with to give you a better answer.
W/D in unit typically will bring an extra $200 - $300/mo in rent.
Same with resale values, if there are new buildings going up all around you with w/d in unit, you may be in trouble when you go to sell. If not, you should be fine.
If you would like some help, just give me a call at 847-533-7115.

Not having in unit washer and dryer will negatively affect the value and appeal of your condo. Is it possible to add them before you list the property? I would be happy to talk to you in detail and preview your home.
