How much value does this zoning add to my land?

[Tab Teehee]

I’m considering selling 2 parcels of land that are infill and next door to elementary school and other businesses. 1 parcel is 11 acres and the other 17. The current zoning is high density residential which the city list as: RM zoning lot size minimums Detached house 6,000 Patio homes 4,000 Townhomes 2,200 Duplex 6,000 Multi unit house 8,000 Apartment/condo 10,000 I’m trying to determine value and am I wrong in thinking the value per acre should be higher than standard residential zoning?
