Very steep, but I was in a pinch and needed the repair made so I could get the furnace in for my tenants today.

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.

You'll need a solid educational foundation before you start.In the meantime, either get involved in real estate or business in some form.

Also sellers in today’s market have priced assets where buyer returns are significantly lowered which is a whole another story about where to buy assets.

After reading posts about out-of-state investors owning/flipping many properties they have never seen in person before due to today's technology, I began to think... are there any situations where you feel like you MUST go visit your property or meet your agent, property manager, or GC in person?

A good realtor knows what is working in their markets and what is not so you should have one on your team as a trusted advisor.Buy and holds are a whole different dynamic, every investor has their own tolerance for what they want in buy and holds... some like cheaper property that have good cash flow today and do not appreciate that much over time and others are willing to accept less cash flow today from more expensive property but theses homes appreciate more over time.

At this point I’m focusing on education and my finances as I work a full time job as a registered nurse (9-530 M-F) and want to be smart about this. 

We are guessing it's value around 750 today.

We were sent the contracts today to look them over, and are frustrated with one of the contracts. 

Invest in your education first, and you'll be able to answer this question and many more for yourself.
