.- I made the transition from residential to commercial a few years ago and I love it, because of the more passive aspects involved. 

Building additional square footage will run $350-$500/sqft depending on your choice of finishes. 

Around here about $90 to $100 a square depending on finishes and complexity of design, which would include driveway, septic system, and no landscaping

Long story short, my partner and I believe there is huge potential in this property for an involved owner.

I understand if there is a free way it will most likely involve a lot of time and would be manual.

AdvantagesSince we are dealing directly with no real estate agent involved, we will save 5-6% on the deal which we will split 50-50.This one is a small advantage, but still mentioning it here.

I want to know the cost to design and build  (3 bedrooms 2 bath) two 10 units   5 up and 5 down building in clairmont, Florida and how many square foot of  land i need, I got a group of investor to get this done Average rent depending on design, 1400-1750.

All for $5,000 down and, $2500 of closing costs and $7,000 worth of rehab, from a private lender, so none of my own capital involved for this deal.If I did a 15 yr term refi, my cash flow would be gone and I'd be losing money.

My full time job is as an officer in the Navy, but I am involved in quite a few side hustles.

You are never allowed to be involved in the management of the property.
