Steps to take when tenant agrees to buy property?

[Howei Yeh]

Hi there BP,

My tenant and I agree on a purchase price and want to move forward on a sale of my property to him. I have sent disclosures. We had briefly discussed using a real estate attorney to guide us through the purchase process but haven't engaged one yet. I am hoping someone can help as I've never done this before. 

1. My property manager says that because he is a RE Agent, he is entitled to 1% finder's fee although it is not in our PM contract. Is there some law that obligates me to pay him? 

2. What steps do I take next with my tenant? My tenant said he would hire a home inspector at some point of the process. Or, should we hire a lawyer first?

3. Are there any ways to mitigate risk if the deal doesn't work out so that I am not left with the lawyer's bill? 

Thank you, all. More questions may follow.
