The area is close to Newark Airport which is a plus and has easy access to Times Square NYC with a short bus ride.

I can buy a book about making a space shuttle doesn't mean I can build one.  

I'm renting a commercial space for a friend and a new day care is moving in there.

You don't need a real estate license to be an investor.It would actually cost you money to hold a license and not actually use it.To get access to the local MLS, you have to pay money to the local Realtor board.

I'm looking for dense pack blown insulation for the front and rear walls, 2" closed cell foam for my basement w/ exposed joists and possibly doing the floor space between the garage and first floor (it's a 1950s airlite) and the attic. 

I was in escrow for a few days and the seller side couldn't give me access to see all 4 units.

@Brian PulaskiI have the correct tradesmans but, it is difficult to understand the scope of work without gaining access to the inside of the property until the current residents are out.As long as major work is not needed then I expect to be done within the 60 days. 

I'm not really excited about leaving an electric heater running unattended, nor do I think that curious, uneducated minds would think it was necessary to run one in an unoccupied space, nor would they appreciate the extra heat in summer, or the extra expense added to their electric bill.I'm wondering if anyone has tried any of these, or if they have success doing something else to help cure a damp basement.Thanks in advance.

For replacement costs on my average deal, HVAC is 3-5K, roof 5-6K, water heater $1K, and foundation can of course vary depending on severity and whether slab or pier and beam as examples.Third, decide if there will be any additions, conversions or demolitions whether adding a bath, converting a room to something else, or removal of walls to open up the space. 

My goal would be to use BRRR and then hold as I would expect the value of the house to increase as more commercial spaces move into the area.
