@Judah Farkas Welcome to BP, this is a good place to make contacts, learn and most important motivate yourself to get out there and break your first deal.
I see you are in Lakewood (which is south of NJ ) but you are interested in North Jersey properties, it's fine just wanted to be sure before suggesting any areas.
I think MFH is the way to start investing in rental properties at least in NJ.
Cities along the NJ north east corridor line are all good.
New Brunswick might be closer to you and you can definitely start looking there.
Up North definitely more inventory in Jersey City , Union City, Bayonne but prices have sky rocketed here.
Elizabeth, Kearny, Rahway are places with low barriers of entry and cash flow.
Start looking on Zillow, Trulia, Realtor and find the properties that suite your budget , call the listing agent directly as that gets him motivated to sell directly to you.
Call as many as possible, run numbers after coming home, get yourself pre-approved, decide on the type of financing FHA/Conventional etc.. talk to lenders and see what they are offering.
Basically BP and other places are good places to connect and learn but at the end of the day you need to go and see a lots of properties before you get one in your hand (after putting an offer on a handful and ending up with one in your favor) this is not demotivating you but giving you the facts how properties with good value disappear from the market in a fraction of time.
Message me if you need to know anything in specific.
Good Luck!!
