Also you might consider appreciation, that could be a good ice on the cake for your investment. 

I used to play pro hockey.

Specifically this is the scenario that occurred to me: Is the landlord responsible for shoveling snow and de-icing driveways and walkways on the property?

One spends free time gaming, the other hockey.

Wasn’t an ice age coming 20 years ago?

With residential real estate you can easily quadruple your money without factoring in appreciation or cashflow which should both be considered icing on the cake.

In this way it cash flow decent already and upside is icing on the cake and not making the cake.

Some of my concerns/questions are as follows:   *  Do I provide Ice Melt and Shovels?

It's in my lease that tenant is responsible for maintaining lawn, weeding, snow/ice removal of entrance walkways and USPS access to mailbox, and any other HOA compliance items, and that if tenant does not comply, the landlord has the right to hire a professional service to complete after giving tenant x-day notice to comply, tenant to be financially responsible for payment of professional service, to be considered as additional rent due in the month immediately following the landlord's providing the invoice to the tenant.  

I would say that since you see a lot of snow in the area, a garage would be a big plus for tenants (not having to scrape ice off cars in the morning, walk outside in the cold to the car, etc.).
