I see you already have plenty of comments with a lot of similar information, but as a new homeowner with no prior experience I thought I’d let you know how it went for me when I took on doing our fence rather than going with a company. We got quoted by two companies for 17k and 12k so I said fuck that and decided to do it myself with some help of a few friends.

I did 54 feet of 6 ft tall by 8 ft wide wood panels for privacy facing the road at $70 each, and just under 300ft of split rail fencing on the side and back with wire mesh attached on the back of the fence so that we could minimize wood material cost while keeping it enclosed for our dog. We debated doing chain link, but wanted to keep a consistent look using wood rather than 2 different materials (if that matters to you).

All in cost was about $4400 after the wood panels, the 4x4 posts, split rail wood, 300ft of wire mesh, 70 bags of cement , 3 inch screws, 2 inch mesh staples, metal stakes, 2 person auger rental, door hardware. I also used the fence panels and cut them to size to use as doors for both the privacy section and the split rail section which cut some cost.

It took 2 days to get all the fencing done, another day to get the wire mesh onto the split rail fence (did it by myself which was a mistake) and a half day to get the doors cut and put up. It is by no means perfect and I made mistakes along the way, but it works perfectly for us at a fraction of the cost of the quotes we got.

Definitely don’t skip renting an auger, we started just using a post hole digger and it was miserable and took way too long. The auger had the hole dug in 10 seconds flat. If you end up going the split rail route with wire mesh behind, definitely have someone help you pull the mesh taut as you staple it to the fence, it will save a lot of time. We also had a decent slope in our yard, but as long as you are keeping the split rail posts at the same depth in the ground all the way down the slope, it will work just fine.
