Probably a bit high on the bathroom expenses, maybe a bit low on the kitchen especially if you want to match the granite countertops and professional grade appliances.

It's not hard to do if you're at all capable, but it takes at LOT more time than you think. If you're not going to be living alone your housemate might really learn to hate your guts.

I'd start on the spare/guest bathroom so your first attempts at tiling etc aren't in the kitchen and master bath. For that matter, waste the $50-$100 in tiling materials and tile a couple sheets of plywood first in the backyard. Ditto for plumbing/electrical. Make some fake runs in the garage walls then cut them back out. Better to learn and make a big mess outside of the prime living areas.

You forgot to add the cost of hiring a contractor to fix what you screwed up, or to complete the job when your contractor absconds with your $ and leaves you owing subcontractors. It happens all the time.

Unless you're really good at home improvement, including plumbing, electrical, carpentry, etc expect to double your budget above. And it will strain your relationships & interfere with your job. Remember that the home improvement shows start & finish in half an hour, when the actual work can be weeks or months.
