Hi-I'm looking for duplexes, starting small...What I'm running across are for sale owned by investors that have several duplexes.So, to hone my skills, I decided to "play at the notion of buying" to use what I learned...

Maybe find such partners and establish relationships were you know they will be repeat customers..Hope that helps..

Buses to NYC run down Bergenline (Bergenline runs in one direction through Union City, north to south) more frequently than buses run to NYC run on JFK or Palisade Ave (in my opinion). 42nd, 43rd, 44th etc. are seen as very nice, and I also like the area around the Monastery (18th-21st St near Bergenline).

You may have to repeat your efforts to find a tenant that does meet all your criteria for tenant selection. 

You can buy a new access card the next time you need to repeat the process.As others have said, google voice is a great temporary option, if you have a phone and can get it set up.

Refi as soon as possible and repeat, repeat, repeat. 

You might want to rinse and repeat.  

I work with a number of investors who are frequently buying in the area.  

And then they repeat that last bit day after day. :)

Sellers or their attorneys seem to frequently question to my having a copy of the key to bring buyers through prior to closing.
