My husband and I wont be closing on our home until mid-November would it be more appropriate to wait until after Thanksgiving, Christmas and New Year to have a housewarming party? That time of year just tends to be busy and crazy for everyone I'm not sure everyone we would want there could make it.
Re: Housewarming party, waiting until after the holidays
Watch Football game on TV with pizza/snacks? etc.
You can do an afternoon open-house - starting the new year in a new house etc.
(Please do not look at a housewarming as a gift occasion)
