Like others indicated above. Don’t do this thinking you will make money. If you do everything right, including your own service and don’t pay yourself for your time you could break even over time, probably several years or more to get back to even.
If you look at 2 newer pins you can have $10k initial investment, depending on the location you could bring home anywhere between $50 and $500 per month gross. Thinking you will bring home more just won’t happen. Probably need to talk with the location on split, should be more favorable to you than the 50/50, that was back 20 years ago when pins were a lot cheaper. Can’t go 50/50 today.
Make sure you have bill validator and keep up with maintenance.
