Also noting used furniture on sidewalks in my neighborhood. 4. 

I told him that I will go over there the next weekend to clean up, cut grass on the parts of the property that are publicly accessible (street and sidewalk).

A go to tool for a good land sales guy ( me) was a metal detector to find those rebars that were put in 20 30 40 years ago.we worked subdivisions that were originally surveyed in the 20s and marked with redwood stakes.. and being CA that means they were at some point burnt down.. so you just looked for OLD little pile of ash's  :)  I had the 100 ft roll tape  could work out declination on my compass for true lot line direction then whip out the metal detector and try to find the rebar in 10 foot area.. worked most of the time.my current project Ivyridgeestatescanby  dot  com  our front lot line splits the sideway in half.. so surveyor comes back after we poor sidewalk  ( our responsibility financially) and monuments the front lot lines with brass markers in the concrete. there was a true art to selling rural lands..

Shovel the snow from their sidewalk, bring them chocolates, coffee etc. 

I spoke with the city and they confirmed that the application was indeed filed and they see no reason the lot couldn't be subdivided  pending the necessary infrastructure was put in such as the sewer tap and sidewalk.

I have had deals stopped dead because someone out of the area demanded "Sidewalk easement" paperwork (I guess it's a NYC thing, which is 6 hours away).

Most homeowners are responsible for the water from the shut off valve at the sidewalk (or attached to the condo) all the way through to the faucets.

@V Krishna I’ve owned quite a few without and where I am in East Austin now has no sidewalks.

I recently installed a Google Nest security camera on our porch, which faces out to the walkway, driveway, and sidewalk.

The heat doesn't work properly in the winter (which we managed to get through) but the unit makes some crazy screeching and thumping sounds with the AC running, especially in the middle of the day when it's so hot you can fry an egg on the sidewalk.
