Seller Financing Help

[Si L.]

Hi BP community.

First post,  
I'm the seller of a SFR, and will be carrying the Note (seller financing) to help out the buyer/tenant who is someone I know.

I have no experience in such deals. 
Is there agreements/contracts out there I can just modify and sign with the buyer?
If so, can someone point me to these?

Or is it better to hire lawyers, title company, etc.  
If so, who do I need to hire in my team to draft up these contract?
Who typically pay for these fees?  Or is it usually split?

Is it better to transfer the deed to the buyer at the time of contract signing Or after the loan is paid in full?

thank you
