Make tenants remove snow or hire a company?

[Steve Balinski]

Hello, here is my scenario.

For those if you in northern states, for smaller multi-unit (2-6) when it snows, do you tell tenants to shovel their own snow, or pay a maintenance company?

Lease says I will take care of snow, BUT 2/4 tenants are on M/M, I'm thinking of buying a snowblower for $300 and offering them $100/MO off rent to take care of it, otherwise its $50/each visit from maintenance crew which can really add up (x2 times today for this blizzard rolling through...Chicagoland). Would cost me about $700 to have tenant do it including cost of snowblower, or $$?? for maintenance company. They are already paying all of their own utilities.
