Mike,
30K for a kitchen?? How much remodeling are you talking about? You will see an increase, but I doubt you would ever see a value increase of that amount just from re-doing 1 room.
I am guessing that value includes all new appliances, countertops, sinks, cabinets, a tiled floor, tiled splashguard walls, and lighting?
The appliances are going to depreciate, so you will never realize full-value on those, other itmes are a matter of buyers' taste. A potential buyer would probably like new countertops, sinks, lighting--they may not like the particular style of cabinets chosen or the layout, however, when you go to sell unless it is really something unique or you are selling to a gourmet chef, a "remodeled kitchen" is a "remodeled kitchen" that is wether the countertops are granite or formica, the floor is tile or linoleoum, etc. and you would probably see the same dollar value increase in the home itself regardless of the $$$ spent on the remodeling, so long as the kitchen was remodeled.
I hope that makes sense
