Out of State Investor - Need Advice

[Jay Miller]

Hi BP - I currently live in Chicago and am relatively new to investing in RE (one flip, one MF - both in Chicago). My mom bought a plot of land in Poinciana years ago and has been sitting on it. I keep getting offers on the place but I'm trying to convince my mom the best play would be to build new constructions ourselves with the help of a full service GC. A quick comp analysis looks like I should be able to fetch $300k+ for a new build (4br/2ba). My question is in regard to costs. Looking online, I see anywhere from $60/sf to $200/sf for new construction, I'd assume depending on finish level etc. In Poinciana, specifically, does anyone have prior knowledge on what I can expect to spend if I hire a full service GC to get this done? Can I build 4br/2ba in the $100k - $150k range? I've also never done a ground up development. What other items (I'm sure there's a million) should I also take into consideration? Any guidance helps. 

Thanks!
