Post frame multi-family new construction

[Beau M.]

Understanding that all municipalities are different, are Post Frame multi family buildings any harder to get approved for new construction inside(your) city limits? Are there any not-so-obvious expenses to why this may not be considerably cheaper way of building(think Morton Buildings)? Are lenders opposed to lending on post frame/pole barn style metal residential buildings? Any other obstacles? 

Looking for input before spending a lot of time researching this, and I may be overlooking something to make this a worthwhile idea to begin with...
