I don't think that we have quite enouh information , but some people have made some good attempts at obtaining it. . As such, this is not really advice, but some things to consider.
As far as buying a lot, you did not mention whether you were financing or not. If a leveraged asset falls in price, you can lose all of your investment and then some. If you really did need to sell it in five years, you are taking a risk.
