I think you need to give us a little more information, such as
1) what does the buyer care about- culture/restaurants nearby, quality of schools, size of the house?
2) What budget?
3) And is that 20 minutes counted at rush hour or just any time? (I’ve seen some very far off neighborhoods call themselves 20 minutes from downtown, but I think that would only be possible at 4 am in a Ferrari.)
