Do not rely on it for legal advice.

I hired a PM to find a tenant for one of my properties which has become vacant.Their agency has a lot of good online reviews and when I interviewed them, I was impressed with their professionalism.He has just now emailed me saying he has a client wanting to buy my property for 150k.I was a bit baffled because last I checked it was worth around 450k.

You can find this online, or at the town hall

You then resell it.It is the same as any for-sale-by-owner and perfectly legal.What is not legal in every state is assignment - getting a property under contract and selling the contract.But wholesaling is legal everywhere.

Realtor says I can pay the $30,000 to reinstate & transfer house over to me in the Grant Deed.Then we pay his mortgage payments until we sell the house... is this even legal?

You can also check their reviews online at Google, Facebook, or Yelp.

You do not have to accept the tenant they bring you, but if they move out you have a legal obligation to mitigate (minimize) your losses.

I was online one day and  found my local REIA chapter and decided to attend.

Rule of thumb is that if you have a legal issue (personal issue) its going to be hard for a court to go after your LLC's. 

This gives her legal capacity to sell.
