(a health, environmental, public nuisance and waste, liability among others issues,)Even if the lease doesn't directly disallow a business from R-1 there will be in contract something addressing tenant's responsibility to protect the landlord property , not creating waste, commit public nuisance, or damage.I would have no problem to a good, responsible tenant for use the residence address for ex. handyman or plumber since he does not physically conduct his business from the home, and all his tools might be in his truck or rented storage, but I still would make sure that I am not being liable for loss, damage to his tools...and request he has a rental insurance, compliance with city regulations.Conducting online seminars is not the same as doing a hair extension, or running car repairs shop from R-1.  

I bought my first property as owner-occupant for a hair under 55k in Syracuse.

My LTRs average 32% but my STRs average 22% even with the theft factor of replacing toasters, silverware, coffee makers, blankets, pillows, chaise lounges, lightbulbs,hair dryers, etc... 

House was a hair under 1000 sq ft.

My First MF offer, after learning what I had my valuation on the property had dropped significantly and my first offer was at land value for the 3 quads, I also offered to purchase the ne across the street at land value as well just to get it out of her hair.

Current rents are a hair under $2,000/month.

If you don't think see the validity in the comparison, and you accept the fact that anyone can learn enough about REI through casual resources, and that the limited success gained of those casual resources is fine and acceptable, and the idea of looking beyond the simple and striving for better rather than accepting limits, then go ahead and change the surgeon to (choose any of the above) the:1 - Engineer that designed the structure of the building you work in, 2 - Person cutting your hair,3 - Accountant that does you taxes,4 - Air Traffic Controller that keeps planes from crashing,5 - The Pilot the flies those planes,6 - The Captain that sails the cruise ships,7 - Electrician that wired your house,8 - The plumber that plumbed your house,9 - Pharmacist that dispenses your meds10 - Software Engineer that designed the software you use,11 - ...I'm sure others can add to this list.
