And I don't know if it holds true in the specific deal but generally speaking, I would put doors on both sides of the building. 

Knock on doors.

Hello everyone, my name is Portia Bright born,raised and sauteed in Harlem New York :-)  I moved  into a townhome in Hackensack NJ 2 yrs agoI am actively researching where to purchase my first multi family home(2-4 doors).

We opened up the dining room and also relocated the door to the back porch.

You maximise income through # of doors.

NJ is a very tough place to loan money from the lender side of things.. foreclosure time lines are for ever.so I don't think your being realistic on what you expect.. but I know Patch of land has done a ton of NJ loans. you can go direct.you need more than 20% cash into the deal.. in most instances in a state that is so tough to work in.credit while important is not the main driver in HML.  

What we have done: all new kitchen 6 years ago, all new bathrooms last year, new energy-efficient windows and sliding glass door, new drywall texturing, new base and case, created a 4th bedroom in the basement (cut a window and finished the room), new HVAC 4 years ago.

I was able to raise rents $100/door within 3 years.

Increased rents $75/door since purchase.

rents would be over 2k per house or door if that was the case and I can assure you rents are not that high.
