Yes, it is reasonable to make an offer consistent with the comps. It is a standard practice to use comparable that are no more then 6 months old as Mike stated below. If you have a good agent representing you they can advise based on the condition, comps, location ect. It is in your best interest to deal with a buyer's agent who can sit down & go over the comps with you.

Joseph is absolutely correct, it really depends on the upgrades of that particular house. Also, some of the recent comps may be distressed properties that skew the numbers. As Jill said, you can make any offer you want and the Sellers can accept, reject, or counter. Good luck!
You can always make the offer; it will either be accepted, rejected or countered.
