Excellent Question. There are of course no easy answers. It would probably depend on where you wanted to be. For instance in Journal square area you can expect $200,000 -$250,000. But ......
if you go Downtown Jersey CityYou will probably end up $250,000-$400,000. In Greenville You can probably get one for 159,000. I have discovered some luxury bargains in the height's as well.
