There are other very important considerations. For me, the quality of tenants is key. I would take a 1% property with great tenants over a 2% property with tenants from hell any day of the week. Even if you use a PM, you will still have to deal with late rent, evictions, etc. I am sure you work full time and are looking to do this on the side. Same here. That's why I choose the former before the latter of the two situations I described. NJ is definitely tough. I am actively looking for a property to house hack myself, and my criteria is to not pay anything out of pocket. I've realized I will have to get very creative to find such a property.
The most important thing is to keep educating yourself. Education will help you understand the market, the pricing and the opportunities. Most importantly, education will give you the confidence to pull the trigger when a deal actually presents itself. So keep listening, reading and connecting! And best of luck!
