I see so much renovation activity and all of the new sidewalks around my houses.

anyone have a good contractor to recommend to put in a new sidewalk for our quadplex in garfield NJ.

Then you get into windows, roofs, sidewalks, parking lots, water and sewer mains going to the street etc. which can add another 2 to 3 k per door in expenses easily.So you could be looking at 80 x 13,000 = 1,040,000 in repair costs to stabilizeNo way a few hundred k is going to fly.

The only issue that came up during inspection was two broken rafters, a couple disengaged shingles, a few holes in the vinyl siding, and cracks in the sidewalks.

Lots are small and awkward, a lot of streets (even in desirable/high priced areas) do not have sidewalks and are very narrow. 

Trees to close the limbs can fall on the roof, in a storm the tree itself can be pushed into the house and fall over, animals can crawl from the tree to the roof and get in the attic and walls, the tree roots can go under the foundation of the house or sidewalk and start buckling things or the tree roots can possibly break into your water supply pipes.  

Each lots are 1/4 an acre with stubbed out city water/sewer, gas, and high speed cable internet with sidewalks and paved street.

From a recent city auction, a couple purchased all the common ground areas of a private homeowners association, including the grassed islands, sidewalks, and private roadway.
