Thanks everyone for the comments, I've been doing a lot of homework for the past couple weeks.
@Marios Hoppas, I have considered Ridgefield Park but I was turned off by the high prop taxes as you mentioned. From my view, such high tax would eat up the cash flow that is already incredibly hard to acquire in this market as others mentioned. For the same reason, @Shivam Patel it is more reason I am avoiding the FHA/PMI double-trouble, especially considering @Mark F. was having no luck getting his offers even considered with an FHA.
All this combined with the fact that these townships in general appreciated something like 20% since a year ago, I am reconsidering altogether if it is better to look in NYC area as people flee or get even more exotic and look around Upstate NY, Connecticut, or Pennsylvania (Philly?). I am halfway through David Greene's BRRRR book and I'm now compelled to deploy my cash for a BRRRR instead of a house hack and it doesn't seem practical to BRRRR in Northern Jersey (or NYC, of course) with my capital (probably reach $100k cash by summer 2021).
I gotta say, my plans keep changing fairly drastically week-to-week; I'm excited to see where my mind is in another couple weeks :) Thanks for bearing with me!
