If you would like to hop on a call I would be glad to connect and see if I can add value to you and your organization.   

If interested, DM me and I can connect you to the organizers so that you are aware of future meetups.

Pay attention to the details and be organized Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?
