Develop Cost for multi-family subdivision

[Robert Martin]

Can anyone give me a range of what the Development Cost would be to take a small 4-5 Ac Tract of land and Develop it for 4 -plexs? Lets say: In a Urban Area with easy access to all utilities. I'm not looking for anything exact. I'm just curious if its $1-2 a sf or $7-$8. So I'm looking for a ball park of what it will take to bring the vacant tract of land up to being ready for builders to start erecting 4-plexs (High Density). Thanks a lot, Robert Martin
