While I would agree with @Jeff Brower about getting a 4plex (I just bought one to owner occupy, so I'm kind of biased) I would have to stay that it really depends on YOUR end goals. Don't do what other people are doing just because you think it'll work. It has to work for you.
In your case, you want privacy and to not have your stuff around tenants. I think the slow flip might be a great idea. Or even the buy a SFH, fix, and rent. Moving into the next fix'er upper and repeating. If you want a portfolio of SFH, or if you want some SFH and some you can sell.
If you want to keep your living expenses down, a duplex might actually be better suited for you. In general the other tenant will cover most if not all of the mortgage payment, each side is generally larger than a 1BR and it has a higher chance of having a largeish yard/shed/garage. Depends on if you think it'll be worth it for a year. But again, consider your end goals and how you want to get there.
