If you don't have any desire to be a landlord, sell it. You won't have any taxes to pay, you'll be able to cash out about 30k that you can invest elsewhere.
If you want to be a landlord and are planning to acquire more, I'd lean towards keeping it for the experience and the long term inflation hedge via that super low mortgage. It's probably right around break-even cash flow wise, maybe slightly worse, and should be positive if you're managing it yourself.
It's not a clear cut screaming keep or sell either way. I certainly wouldn't buy at that price, and in a vacuum selling is probably more optimal math-wise, even with frictional costs, but it's close enough that it'll come down to your goals and preferences.
