Based on your current location, I suspect I know the costal area being talked about (former PNW resident). And I have had similar thoughts about such a plan when I retire, but I've always assumed it would effectively loose money and simply justify my desire for a larger collection.

You need to factor in how much of the town is rentals / seasonal. You might be able to make a go of it in the summer, but the off season is an issue. The problem with a lot of that coastal area with all the seasonal/rentals is that it is hard to establish a reliable customer base. People head there from PDX for a weekend away and usually just stay at the rental and the beach. You absolutely need to make it an all ages establishment, which makes it more complicated from a licensing standpoint since most profit is in drinks food. You would really need to do some good advertising along the coast to pull in people willing to drive 15min to entertain the kids on a rainy day - probably try to get a flyer into VBRO units.
Honestly with the pandemic you are seriously stacking the deck against yourself in an endeavor that already has a very difficult margin of success. I suspect that breaking even on any loan will be impossible in any long run. If you are going to take out a loan then my strong advice is don't do this.

If you do decide to make a go of it I really hope you succeed, since I would love some pinball when I make my costal trips.

edit:
The other factor is actually getting permanent tenants in the part of the building you want to lease out. No one else is really starting business in a pandemic, but even outside of that getting stable tenants is tricky and you need to be ready to handle times when you have no active leases. The reason most commercial property owners have multiple buildings is to buffer against vacancies - they can write off the losses on one property while all properties as a whole keep things afloat.
