House, remember too, that condos and townhomes are usually associated with some sort of "association" that can often turn out to be run by tyrannical power hungry little bitches and then you have the fees to pay as well. Houses can too, but not always like townhomes and condos are.
Plus I think a house holds value much better than townhomes and condos and are often built better too. Not to mention the potential for a private yard.
