Boy, and you thought the grocery thread would be challenging for us to be accurate!!
Ours varies from year to year, depending if we are doing home improvements. Without any home improvements included, I would guess we spend around $500, my best "guesstimate", mostly things for the yard such as fertilizer, mulch, flowers, pond maintenance, etc. We have all the yard tools one could possibly need, so no need for any purchases there.
Now home improvements are another story.
Right now, putting 1/4 inch drywall up over plaster walls in our dining room, crown molding, trim around the bottom, paint, mud, misc items, probably around $400. Dh and I are doing all the work ourselves.
Last November replaced all flooring on our first floor for around $9000. Includes hardwood, carpet, vinyl tile planking.
Three year ago a new roof with solar powered vent, 6" seamless gutters and downspouts. Around $6000. We had slate, replaced with plywood and 50 year architectural shingles.
About 7 years ago, installed a vent-less gas fireplace. Had a custom-made oak corner cabinet, floor to ceiling, to put it in. About$3500.
Before that, not sure of the years, replaced 22 windows. The kind that tilt in. LOVE THEM! Worth every penny of the $7000 we paid. Also, had the whole house rewired, more electrical outlets installed, and phone and cable lines in every room. Well, no phone or cable for the bathrooms! We had the old fuse box with the round fuses. That was around $4000.
I am sure there is probably something I am missing, but these are definitely the larger improvements we have done.
Oh, almost forgot, they are replacing gas, water, and sewer lines on our street. They also will relocate everyones gas meters to the outside of their homes. This started about 1 month ago. Our only expense will be replacing our sidewalk and curb. Not sure of the price yet, but there will be many people going together and using one contractor. We will get a group discount

! Judging from what neighbors on another street paid a few years ago, that will be around $1200.
Oh, and our home is around 2000 sf of livable space, not including an attic that could be finished, and a basement. Our yard is not big as we live in town. It is around 1/4 acre.
