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.

However you choose to calculate it, make sure you consider the worst case scenario.

The owner of a successful business has systems in place to function without their presence. 

If you choose to invest in that area I would suggest looking at the new builds and see what options they are providing.

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.

Choosing a firm really depends on what your needs are.
