Housewarming cards are a niche greeting card category, but there are a ton of fun ones out on the market today! Especially during this time when housewarming parties aren’t really happening, sending the new homeowners a little something in the mail is a nice gesture that will brighten up their day and mark the occasion. Buying a home is a huge deal! My favorite thing to do is pair a card with a Lowe’s or Home Depot gift card. If there’s anything new home owners need, it’s some extra dough for a home improvement store. Some of these cards would also be good for realtors to give to their clients!
