You are only talking in theory and not giving enough information. Why do you think you can just split a single-family into two units? No one is going to allow that and construction-wise, it is usually not cost-feasible for the output rent on such a large property. It's also unlikely that you can convert a single-family home into a community center (not sure if you mean an actual community center or co-living space). To do Airbnb, you would have to furnish to the nines and add tons of amenities so it is group accessible. Think $150,000-$200,000 in set up on that. Why are you looking to buy such a big house to rent, the numbers usually won't work unless you go nuts on the design.
@Jonathan Greene, I appreciate the advice especially on the costs. I was just looking to see if anyone has done such deals before.
further context: its a one-story (4k sqft on 15k sqft lot with permission for duplex). Sale price is 10% below market value and Seller financing available.
