If so you may have a harder time.I think @Brandon Turner talked about having the seller break each property out in a multi-property sale so that you can see their motivation and the value that the seller has in their own mind.

We have flipped one single family and intend to do another before moving into multi-family. 

I wonder how does it work with purchasing multies (>4 units).

I am always analyzing SFRs , multis in my market, right now it hard to find cash flowing anything. 

Making some money on the side while doing this would be fantastic, but I'm more concerned about the education to be gained from the opportunity.My rough plan is to gain enough experience to become a wholesaler myself, and use the profits from that to jump into REI (Single-Family homes and Multi-Units) with a strong foundation.I'm currently residing in Cumberland County, more specifically the Vineland/Millville area.

Is your current rental a single family and you want to get into a multi and that is why your selling? 

I used a local realtor recommended from a friend and she gave me an email list of multis and income properties How did you finance this deal?

I am trying to decide between the various submarkets in my area to buy and hold small multi-family rental properties.

I prefer small multi-family but am open to SF.

Regardless ask about the cost to start- do you need to pay REBNY dues, order business cards, pay for advertising?
