moving in advice please

so me and my boyfriend have been thinking of moving in together, well technically me moving into his parents place. Of course he pays rent & so would I but I just wanted to ask for some of your guys experiences if any with this or advice and tips ???

ADDING ON: okay so I’ve gotten a few responses saying this is a bad idea , even if I’m close with his family?? 😕 I mean I really do have a good relationship with his family I don’t think it could become stressful

THANK YOU EVERYONE for the advice and tips !!!! 😊
