I added some general property maintenance obligations,  such as keep and maintain the exterior of the dwelling, garage, all out buildings and component parts thereof clean and free of all foreign objects and substances, keep and maintain the driveway, sidewalks, walkways, porches, patios, garage floor and other surface areas clean and free of all foreign objects and substances, keep and maintain the roofs, gutters and downspouts clean and free of all foreign objects and substances, keep and maintain all plots of ground prepared for plants, including the plants grown in such plots, in an orderly, attractive, and healthy condition, keep and maintain all garage door remote controllers in good working order and, at the end of the lease, return all garage door remote controllers to Landlord, and supply and change the refrigerator water filter cartridge, if any, at least every six months or sooner if prompted to do so by the filter change indicator light on the refrigerator. 

This seems very expensive to me, particularly given how frequently it can snow here in Wisconsin.The property I'm purchasing is a 4 unit on a small lot with about 5 paved spaces off an alley for parking, two walkways on entrances and a short stretch of sidewalk. 

If tenants are parked there, the plow won't be able to clear much, so I'm questioning if it is better to just limit the services to shoveling/salting the sidewalk, walkways and stoop. 

The HOA master covers the outside (roof, walkways, etc.) and the landlord policy covers the inside (drywall, cabinets, appliances, etc.). 

It was a very awkward layout (kitchen upstairs) bedrooms were also walkways - argh!

* artificial grass around walkways).

Impervious area includes walkways and driveways.

However, it turns out my construction loan won't pay for the entire project as I had originally hoped, so I'm going to build up cash savings the next six months to pay for all the non-loan covered costs out of pocket (Loan will cover excavation and house build; cash will cover appliances, exterior paint, driveway/walkway, permits, closing costs, temporary fence/toilet rental for contractors, etc). so I'm not terrifically in debt at the end of the project.

We will give them ample notice that we will not be renewing these leases Our plan is to upgrade the property at that time to include:New concrete walkways out side, new stairs and porches for the upper unit.

Thanks @Jonathan Klemm for the mention,@Christopher GrannenYou are allowed to pour a parking pad on your own lot, as long as it is accessed from the alley, Additionally, this typically does not require any form of building permit as long as the property is not located in a landmark district, or have any of the excluding elements as listed on the link below:"Exterior WorkNon-combustible sidewalks, patios, walkways, parking surfaces, and driveways that are not located in or on the public way, not more than 30 inches above adjacent grade, and not over any basement or story below."
