<prompt> Human: I have a pretty secure job and I have about 80k to put down on a down payment. With housing prices so low and interests so low, it makes me feel like I should take advantage of this and just buy the LARGEST house I can potentially afford. Im in BellevueRedmond area Washington and theres no place to go but up. I know the number one rule in investments is diversification but Ive maxed up 401k, IRA for the year, I dont want to get into stocks or bonds right now, and no money market, CD can surpass 3.85-4.25.So what, buy the largest house I can?  <response>: Buy a house in a nice place close to your work and get it as big as you anticipate needing.
