Thinking it was impossible for someone like me to get into it.

You really wont get Cash flow from rentals, not saying is impossible but its really hard to find a property that will give you positive cash flow.

They go relatively quick, but are not impossible. 

Honestly, you will have a hard time finding BRRRR properties with FHA nearly impossible to find and qualify and to win the offer over better cash offers.  

It's impossible to respond to your first forum post knowing so little info about you and the deal.

But it's impossible to say if your current personal home would make a good rental, without crunching numbers. 

Double Closing are nearly impossible in NJ anymore if you want title insurance.

Now, I know you know a lot of this, but I just wanted to have fun pointing out your exaggerations as much as the "anti FIRE" crowd points out the "impossible". 

But also remember the courts you will be walking into for the most part are pretty landlord friendly, and if the tenant has nothing, it might be nearly if not completely impossible to collect on any amount that they dont pay.Also remember you ARE required by state law to minimize damages to the tenant who moves out, and you are not allowed to double dip, ie charge the tenant who is moving out and charge a new tenant at the same time.Are you sure it will really take you 3 or 4 months to lease your property? 

Other areas (many areas in my experience) it’s really hard or nearly impossible to re-zone because the community (and zoning board) just doesn’t want more multi families in the area.
