I would count on 5 or 6 hours of work, on average, per rental (that is, per each party that rents the place). That includes plenty of dealing with interested parties who don't rent in the end, cancellations, billing, cleaning, updating info online/advertising, fixing stuff that breaks, paying bills, etc. I think you'll be lucky to make minimum wage when all is said and done and I wouldn't touch something like this with a 10 foot pole (because I briefly managed a nightly rental, good lord, never again). No way in hell would I pay a chunk of capital for a stressful part-time job that pays $10k per year (which I also think is very optimistic).
But like Iamlindoro, I wish you the best of luck.
As Arebelspy is fond of saying, if you want bond-like returns, just buy bonds and spend your free time goofing off. If you want a JOB, analyze the "investment" as such - doing a job. In this case I think you'd be better off flipping burgers and putting your downpayment/closing costs/reno costs in VTSAX (or anything other than this house idea, really).
