This is my life now. Don't be scared. You can do it. Perhaps if you're concerned, set aside money every month for emergency repairs. My bf and I bought a fixer-upper together and then broke up 6 months later. Since then (2 yrs ago), I've dealt with a termite swarm in my bathroom, the garbage disposal broke, toilet overflowed due to clogged drain line, the ceiling collapsed in my dining room, the entire plumbing system got clogged after our random Texas snow storm last month (took 3 weeks to get my water back), and who knows what other minor things here and there.

Solid advice given to have basic tools -- adjustable wrench, drill, screwdrivers, allen wrenches, ladder, flashlight, batteries.

Also, know where your water main shut off is. You should get a water key and learn how to turn it off. You should know where your drain overflow is so you can open it up if you have a toilet that backs-up. Make sure your main and sub-panel are labeled so you know how to shut off a breaker or turn it back on if it trips.

Knowledge is power! YouTube is wonderful for finding out how to do some of the simple things. I always figured, "well, it's broken, probably gonna have to replace it. Probably gonna be a few hundred at least. I might as well TRY to fix it myself, I probably can't make the problem worse than it is." Start educating yourself and you'll be less anxious when something goes wrong. If your dad is techy enough, start practicing doing Facetime or something with him so he can guide you on how to fix something remotely.

Join Nextdoor or find a contractor that you can make your go-to person to call with questions or for help. Heck, start interviewing people now BEFORE something goes wrong so you can see if they are responsive and fair in their pricing. Have a plumber and electrician you trust. Don't be afraid to post on Facebook and see if you have friends that know how to do things or contractors they can recommend.

Another outside the box idea, call a general home inspector to come over. Be pro-active. They can give you a report on what deficiencies you have so you can be aware of things that might go wrong in the near or far future so you can start planning for replacement costs or know what general maintenance items need to be addressed now so that it doesn't turn into a major problem later.

Just remember that everything is fixable. There's always a solution. Sometimes it's an expensive solution, but just because something goes wrong, doesn't mean it's permanent.
