My question is what value would I offer to a broker if I was simply wholesaling and why would any broker want my license on their wall?

I'm not sure about Massachusetts, but in Oklahoma, or my lease, I can give a 24 hour notice to enter the premises for inspections/repairs.

(My wife refuses to enter most of them). 

The tenant paid me rent in advance, but signed an Early Termination agreement 4 months after the lease was entered because I was going to evict them but gave them a way to end this amicably.

I question if my HVAC person simply has more work now and can charge a premium. 

We can definitely connect and share ideas, advice, or just simply make money together.

I certainly still have the option to back out.I'm tempted to back out simply because I don't like being manipulated and lied to.The deal is not a killer of a win.

Should purse a consulting type of business or can I simply establish a property management company with certain limitations since I do not plan on acting as a real estate broker?

My other strategy is simply go off of the MLS and then I work with my RE agent who understands investment properties too, to look up comps for sales and rent.

Another option is for you to make the payment to the note holder, you could simply be a tenant and do that.A bigger issue is changing the insured on the insurance policy, this can be arranged with the agent to show you as a loss payee or an additional insured.
