We bought our first house a few years ago-- a 1920 fixer-upper, and have done almost all the reno ourselves (refinished floors, drywalled kitchen, laid countertop tile, built fences, etc.) with no experience, other than watching my father do some of these things when he was alive. I keep a blog about it, so I can remember how to do it again next time! In other words, if it's needed fixing, we've probably done it and recorded every little misstep for posterity
. We still have a lot to do, but it's been one of the best decisions we ever made.
I whole-heartedly endorse the shop-vac WITH WHEELS. I love ours. Great for vacuuming the car, too! And we bought a Ryobi set on sale that I've loved with a cordless drill, circular saw, super powerful flashlight, 2 batteries and a charger (maybe $115 or so...) and a $20 set of cheap drill bits/screwdriver attachments, etc. It's come in handy many, many times, and then we've bought more expensive specialized bits if we need them; otherwise, the cheapos have been fine for little one-off things.
If you do ever end up doing anything more than the usual homeowner upkeep, a palm sander is the other thing I could not live without.
Consider yourself lucky with a newly redone house-- we had to completely rewire (hired an electrician who let us "help" to make it cheaper), add central heat and air; we had a big fat burst pipe about a week after closing, and decided to gut the kitchen a few weeks into the reno-- among other various stupid ideas.
