Check exterior grade, you don't want water problemsHope that helps....

Expecting about 20,000 sqft of construction (units and common areas).Related info:Type:Garden-style2-levels with mix of 2 Bed/2Bath and 1 Bed/1Bath unitsMid-grade constructionSite info:Flat land, no major grading work is neededUtilities are yet to be connected (the site is in a developed neighborhood with good road access and utilities at curb side)Expansive soil (known for this region)Thanks!

As appraisers rarely make that kind of error I would hazard a guess that the sq ft is below grade and included in below grade sq footage on the report.

I am considering investing in an area that is a C minus (that is my estimate of the grading) - Clementon NJ.

Unfortunately, this is not  a home that I would expect to appreciate at all and its not in the best of areas (I've seen many people grading areas on this site, I'm not super familiar with the scoring system but I'd call this a D area). 

I have been using rehab grades (light, medium, heavy, extra heavy) with a corresponding $/sq ft. ie.

- what kind of existing slope/grade?

You can do some grading around the property to stop water inflow.

Someone who looks like they don't have the change to ride a bus or appear to be so stupid they failed 2nd grade is not very likely to have anything for rent (and if they did it would be not be the smart choice for someone to rent from them).Gail

There should be demolition/existing condition plans, site grading, roadway plans, water/wastewater/storm, and detail sheets.
