Have you changed how you handle fund distributions? While it is typical to re-invest the distributions to buy additional shares, this may not make sense if you want to get a little cash to use for the home purchase. While you may already handle this, it isn't mentioned in the question.
While it likely won't make a big difference, it could be a useful factor to consider, potentially if you ponder how risky is it having your down payment fluctuate in value from day to day. I'd just think it is more convenient to take the distributions in cash and that way have fewer transactions to report in the following year. Unless you have a working crystal ball, there is no way to definitively predict if the market will be up or down in exactly 2 years from now. Thus, I suggest taking the distributions in cash and investing in something much lower risk like a money market mutual fund.
