Investing in a single stock or any stock IMO is the stupidest thing you can do if you are going to purchase a house soon…with your down payment…
One “accounting” irregularity can destroy your lifetime of savings and if you are looking/waiting to buy a house, keep it in short term investments where you can buy a house if you find one you like.
The name of the game is not to “make” money, but to wait till you find a house you are happy living for the longer term (5, preferably a lot longer 10+ years or more even)
