Would you rather- Bring in more Mobile Homes or Build Duplex's

[Allen Martin]

The Question- Would you consider building Duplex housing instead of bringing in more mobile homes on the extra land.

I am planning on purchasing 5.5 acres of land that already has 8 mobile homes in place the other acreage of land is mainly grass area. These 8 homes should cashflow once I get lot rents up to Market Value. I got the perc test done today and it came back good! Meaning I should not need an engineered septic system. After talking with the lawyer to write up my lease she threw the idea of building duplex housing in the remaining acres of grass vs bringing in more mobile homes. As far as location it is in a great area between Athens and Hsv, AL. 

How much would building a Duplex of 2 bed 2 bath cost 

Thanks for your help
