You can see this effect pretty drastically along the Blue Line where many of the neighborhoods it passes through do have a relatively large inventory of single family homes and as you get further Northwest you have fewer good transit options to downtown and the Loop. It applies to renting as well. Rentals close to transit command noticeably higher rent as well.

There's so many factors that it's hard to make direct comparisons, but for example you can look at homes near the Irving Park blue line stop (which also next to a Metra stop) and then similar home just a few miles West where there are fewer transit options. It's a pretty drastic drop off in home prices for relatively comparable neighborhoods.
