If your home is on the market at this time of year or you are planning on viewing homes on the 31st, may I give you some words of caution.
On the evening of "All Hallow's Eve" try not to schedule any showings as your lights being on, will probably attract little ghouls & goblins & you won't have time to dole out the candy as you'll be getting your house prepped for the potential buyer!
On the flip side of the coin, I can't imagine trying to show properties on this evening! With little bodies darting back and forth across the roads, it will be a really dangerous time to be watching out for addresses and still remain aware of all the kids.
Wait 24 hours, it will be safer and more relaxing for everyone!
