My other example of this is:
I live in a neighborhood in which there are 5 basic home models. My BIL lives in one and there is cookie cutter version 4 doors down. The other house has the original bathroom/kitchen, but has nice curb appeal and a two-car garage. BIL's house only has a one-car garage, so-so curb appeal, but we redid the bathrooms and kitchen, and replaced vinyl floors with bamboo and replaced the aluminum sliding doors with wood French doors.
The other house has been on the market for months and has decreased the price twice. My BILs house had two solid offers within a month.
If you don't care how long your house is on the market, just offer a few bucks at closing. But in my experience, a) people buy with their emotions, and b) very few have imaginations--so they need to see the vision. You'll sell your house quicker if you make those improvements, IMHO.
If it were me, I would try to come up with a few thousand to update as much as you can. I wholeheartedly agree with consulting with a GOOD realtor to find out exactly which improvements are going to give you the best bang for the buck. Our realtor is great--she gave us a checklist of improvements to consider and what to expect if we a) did nothing, b) put in some cosmetic improvements, c) went all in and fixed everything. We went with "B" (although we had already updated the kitchen when MIL moved in in 2007) and we achieved the top of the range of her projection.
People are busy today. They just want to move in.
