Probably more importantly safety items like hand rails, side walks and stairs.

My township has strict laws on height of grass, no cracks on sidewalks, trees need to be trimmed to 10 feet above sidewalks and 14 feet above street.

Well we still need to replace the driveway and sidewalks, but that is underway.

The basement already has a separate entrance that is accessible from the sidewalk.

I was wondering how you address de-icing sidewalks/front porches/outside stairs on your SFH rentals.

When you start seeing bullet holes in homes,broken glass in the streets,blood on the sidewalks and police tape all over the neighborhood than you are in a war zone.

Do your due diligence on the infrastructure cost to bring in curb, gutter, sidewalk, water, sewer and utilities if they aren't currently there, as this isn't cheap. 

Install it as close to the sidewalk as the city will allow and fill it with paperbacks.  

I live in a nice property where it says I'm responsible for the "yard", which includes trees, as in your lease.When the trees overgrow to where they infringe on access to my sidewalk, mailbox, driveway, patio, and roof, I don't hesitate to go out there and snip away anywhere I can reach. 

I would pressure wash all the concrete sidewalks & walkways.
