Potential tenant has Realtor

[MONICA WATSON]

I am trying to rent out my first buy and hold. I have someone that is interested and they had a realtor to contact me. The Realtors commission is half of the deposit amount and she stated she has detailed information, credit and background on tenant. The tenant also has a section 8 voucher. My question is do the Realtor facilitate the lease and do I still have her fill out my app if I'm provided the information? I have not formed my own lease yet,,Can I use her Realtor to my benefit? I'm a little throwed off as I planned to do rental process myself. ANY ADVICE?
