I am not saying your wrong(I'm not old enough to have any experience from this) but after talking to alot of people this is were opinions have varied alot. Even though you will have less worries about structure, plumbing, electrical etc. with new homes, you will also get a lot less home for the money. I have found some really nice new homes for 180-200. But then I can get a very similar home with twice the yard that is maybe from 84-95 that is still $50k cheaper. I know most of those homes will need to have upgrades if its not already done, but you get alot more to work with.
What part of the country are you in, that new homes go for $200,000?
That is a very reasonable price. I understand your reasoning about getting the most for your dollar, and if you can find a near new, nicer home for less money, then that is a good choice.
