While each floor is ~1200 sqft, it will be a challenge (though not impossible) to reconfigure the building to four units ... though you might be able to segregate the ell from the remainder of the building and turn it into a multi-floor unit.You will need a building permit to renovate that building whether you reconfigure for four units or retain it at three.  

The property is selling at $194,000 4 Bedroom, 2 Bathroom Duplex with two car garages on the bottom floor, a nice deck per unit, and dated interiors (built in 1995).

Way back before I owned the place (1986) the place flooded with about 1-2” of water covering the basement floor.

Used HELOC for down payment remodeled the first floor right away and moved the tenants from upstairs to down stairs and raised there rent $100mo.

I am talking with my bank to refi my primary residence, but my commercial mortgages have prepayment penalties and are set by my bank's internal interest rate floors, since they are balance sheet loans, fed rates won't bring them any lower.My HELOCs are lower now, but nothing I can or will be doing with those, as they will always remain floating, so there is no benefit at this point.

I found this on craigslist and asked the landlord at the time to pay for flooring for the front space.

Complete remodel of interior and opened up the main floor plan which helped a lot What was the outcome?

Also, it seems that everyone can slap some vinyl floor and a coat of paint and call themselves a real estate flip mogul.

I am looking for a general contractor experienced with concrete tilt-up industrial buildings for a  consultation.
