A. In space-deprived New York City, you will certainly pay more for the privilege of noshing in an area specifically designated for that activity, agree our experts.

How much more is a little harder to pin down.

Real estate broker and asset manager Roberta Axelrod of Time Equities says you should expect to pay 5 to 10 percent more for an eat-in kitchen, 10 to 15 percent more for a non-enclosed dining "area," 15-20 percent for a separate dining room, and 20-25 percent if you can convert that dining room to a bedroom and still carve out an area to eat.

"If a dining room is placed in a way to be able to make a decent third bedroom and still have enough room for dining in the foyer or expanded foyer, then the dining room adds a great deal," agrees real estate broker Deanna Kory of Corcoran.

Expect to shell out on the higher end of the range for dining areas that appear where you least expect them, notes Axelrod. For example, she says, "a studio purchaser might like a separate dining area but wouldn't expect it, while a 3-bedroom purchaser would expect room for dining outside of the kitchen."

All of these ranges assume apples-to-apples comparisons, of course.

"There may be any number of 'negatives' that could pull the price back down," notes real estate broker Gordon Roberts of Warburg Realty. "Is there only one bathroom? Does the apartment need renovating? Is it on a low floor or in the back of the building? I'd look at three or four closely comparable apartments and draw my own conclusions on what is most realistically price. If you still feel you need a safety net before signing on the dotted line, your offer to purchase could be contingent on an acceptable appraisal."
