I also “hoarded” my down payment in a savings account. I’m really not sure how else to do it. It was a lot of money that I saved quickly and used fairly quickly. As far as I’m aware, there aren’t a lot of other places to put that money. The small return on something like a CD vs. the hassle of figuring that all out didn’t seem worth it to me. I certainly wouldn’t feel comfortable putting it in stocks or something.
