Let's say I need 200k down to close a construction loan of 2 million.

If you want to finance construction as well, I am not sure how many people would offer financing as a second lien.  

I have a degree in construction management and want the extra cash to jump start my buy and hold portfolio.

The office walls were demoed, and conference room(s) constructed. 

We've got an opportunity to buy 7 fourplexes all the exact same construction.

I would say you can get a duplex here in the area for around $100 - $120 or a 4plex for $225,000 - up to $325,000 (for newer construction).

I have been working for major companies for my career so far doing engineering design, equipment and property maintenance, assessments, repairs, contract management, construction management and much more.

. #3 (the conversion to a duplex) we have finished one unit and have that rented, now starting construction on the upper unit.

Depending on your reserves for initial construction.

I am debating on a buying at wholesale and remodeling or doing a demo/new build and am curious what new remodel/new construction cost run on average per sq/ft for mid level builds.
