I have a deal pending - multi-family house in Union City, bordering Jersey City.

If I were a betting man, I would point the area south of USC - west of the 110 freeway.The boundaries would be JEFFERSON BLVD to the north, SLAUSON to the south and stretching westward all the way to BALDWIN HILLS and ending at La Cienega on the western border of this rectangle of speculation.I've personally seen "in love" yuppies taking a sunday morning stroll at Central and MLK blvd.

@Dan Salim I would highly advise you to get some advice from a cross border tax specialist (accountant/lawyer), if you haven't already done so in setting up your LLC, as you could potentially face unfavorable tax treatment when repatriating the income back to Canada.  

How about towns that border it, Woodland Park, Pasaaic, Elmwood Park, Wayne, Haledon, Prospect Park?

Correction - you absolutely CAN do 1031 across state lines.Per: http://www.1031exchange.com/faq/Exchanging property across state borders is a very common thing for investors to do.

The house is on the outskirts of a booming town which borders raleigh.

So all my lots bordered county road and I had to come through the lots to get to my tree farm and use my established logging roads which are pretty stout as they have to handle 40k pound trucks full of the northwest finest douglas fir logs.. on one section I was able to dedicate the road way through the parcels to my gate onon my southern entrance the lot crossed my logging road.. so I retained an easement for ingress egress and utilities. as I was working on a monster Zip line park ( but that's another story). so the buyer of the 10 acre parcels wanted animals and as such he wanted at gate at the beginning of his property and were my gate was at our common boarder.. at first we were a little miffed as we now had to open two gates instead of one....

I am always on border.

I'm in Hallandale Beach on border of Broward and Dade counties.

Yeah the Woodruff Place neighborhood is on the border of 46202 and 46201, just north of Arsenal Heights.
