Exterior property maintenance like lawn mowing and snow removal can be the tenants responsibility. 

Has the snow melted up there yet?

You are thinking this is a problem with a leak with freshwater but this time of year basements often flood because of spring rains/snow melting etc....so could be coming in the from walls, up from the drain tile, not likely to be coming from the sewer if it isn't sewer water but that can't be ruled out either. 

If you didn't shovel snow after a snow storm, there's a slip and fall, YOU are responsible, not the LLC.

The 3rd one I pay the snow removal and my neighbor mows the lawn, we share the driveway.

Lawn care or snow removal?

New build prices have climbed since my post and the least expensive new build is likely low-mid $300's now.

@Andrew Bravo no, I meant ongoing maintenance - for example, when you're not living there you can either pass the grounds costs (lawn, snow, etc.) on to the tenants or have them taken care of.  

@Arian MustafaArian,This is Brandon who you reached out to about snow blowing/plowing this past winter.

For LTR who cares two prong is fine.The popular roof style was a very shallow pitch and we do get snow.
