Improvement/Entitlement Cost of Raw Land in Oklahoma City

[Rob Nichols]

Oklahoma BPer's,

I'm looking into purchasing some vacant land around OKC with the intention of building duplexes.   It'd be approximately 4 acres on a corner lot between two roads and next to an already established neighborhood so it's within easy access to utilities.    Does anyone know a rough ballpark on the soft costs of upgrading raw land to a point where you can start the vertical build (permitting, other entitlements, grading, utility connections, water and sewer, etc)?  

Thanks!

Rob
