Wiss tin and aluminum and small sheet metal cutters are the best so keep that one and find a hook or buy a tool box to keep it in and it might last you a lifetime.
congrats on buying your home. in case you haven't spent time on this forum before there are tons of things to read and learn and we've got a growing membership that most of them can build something or fix something with most any tool, but you'll learn to know what are the best tools for the job so you're tool inventory or wish list will grow substantially.
your skills will grow if you just read and ask questions, but your wallet will wonder if it might ever see $100 bill in again for more than a few days.
good luck
