Jc heights or Harrison , NJ for good investment

Hello BP pros

Am a newbie here. 

looking to buy a property in Jc heights or Harrison , NJ for good investment

(Good rentability and decent appreciation)

I always knew that Jc heights is an amazing area for appreciation potential and constant rent . I have been in the market in 2015 and wasn't able to finalize a deal. I know people who bought back in 2012-2015 would have seen their properties appreciate quite a bit as that was the right time.

Asking the pros here if it's a good time to still buy in Jc heights area - a multi family with 2 or more units

If so which areas are still good to look at? Not really looking for lot of shoddy houses/TLC work but decent houses with minimum repairs

Also another PATH stop which has slowly become famous in last couple of years is Harrison - lot of new buildings up there . Is that a good place to invest instead ? What abt the rentability and appreciation over there? 

Thanks in advance for all the responses.
