Are there other assets involved.  

Congratulations on making a excellent decision to get involved in Real Estate!

My family's farm is multi-generational (currently 6th generation, to be exact), so I have been exposed many of the aspects and tangents of RE via involvement with the family business including generational wealth management, land acquisition, rental homes, tenants, etc. 

I would just sit down with your agent and express your feeling and thoughts and ask her to put together a new plan , also ask to be involved  in the new marketing and and so on, But let the agent lead the way as it is her field of experience. 

There is lot of work and due diligence involved.

These plans are offered by a handful of specialty providers, (you can find several here on BP) and while you will certainly want to have your own CPA involved in helping you evaluate such a move and operate your business, most CPA's will not form or support the structure itself.

It depends on your track record and relationships, but more importantly what the deal can do for everyone involved.
