L.B.
A tool box with tools. Hammer, both kinds of screwdrivers (different sizes), scraper, nails, screws, electric screw gun, masking tape, duct tape, black permanent marker. Ask some male friends what tools you should have. Do you have a vaccumn? Other than that you know you don't necessarily need to spend the money. Put it in savings and pay extra on the loan or just save for a rainy day.
Also check the weatherstripping around all your doors. Including the garage door if you have one. Buy extra furnace filters and change regularly for cleaner air and efficiency of the unit.
Congratulations on your house!!! That is Awesome for you and your kids.
God Bless,

Replying to another post: cheap windows are NO bargain. The seals will break most likely and then at some point you'll pay for them again.
