Investor Building in Memphis

[Jamie Parker]

What is the cost to build in memphis on average. I want to make an offer on a 2 packages of vacant lots looking like 10-20 builds. If I'm getting the lot for 25-35k am I listing @ 225-250. What are the hard cost(sewer taps, GC fees, permits), time frames from surveys to footers to frame to ruff ends?  

Looking to factor the cost of money. Timing is what it is. BFR (building for rent) may be an alternate exit with cash out refi. Main objective is building for sell.
