I think my husband would want to put it toward a down payment on a new house. We're currently very slowly saving a down payment for a house with more land and fewer neighbors, and that would push us up to a full 20% downpayment, at a minimum.
Personally, I'd probably put half toward that, because it is important to him, put enough toward our monthly expenses that we could max our 401ks this year, and the rest into VTSAX in a taxable account. We don't have enough saved to retire yet, and I would hate the commute I'd have if we actually moved to a new house this year.
