Using a Realtor for lease sign up / a la carte services (Virgina)

[Nerissa Marbury]

I would like to use a realtor to help lease out my rental property in Richmond, VA. At this time, I am not wanting on-going property management services.

If a realtor helps a property owner rent out a property (i.e., marketing, showings, overseeing signing of the lease, delivery of keys, and move-in inspection), is there a Virginia law or regulation that requires the realtor to use his lease agreement instead of the lease agreement the property owner provides?

If there isn't a Virginia law or regulation, why would a realtor insist on using the realtor's lease agreement and "not budge"
 on using the lease agreement used by the property owner for 7+ years counting?

As a property owner, what risks do I open myself up to by having to adhere to and govern a realtor's lease agreement that was not written specifically for my property?

Two other realtors have agreed to use my own lease since I am not utilizing on-going property management services. However the realtor I wish to use, insists his lease agreement must be used so he doesn't open himself up to risk. He isn't doing a good job in explaining his point of view, which why I am here. I hope someone else can explain it to me so I understand.
