If you are on a "Website as a Service" contract, we do require that we host the website... at least until the end of your contract term at which point ownership is transferred to you. During your contract, we will put you on our "Basic Managed" Hosting plan (
details here) which currently would cost $20/month.
After the 2 year contract expires, we will drop your monthly payment down to the "Basic Managed" hosting plan, but you are free to choose whatever hosting/plans you want at that point.
Please get in touch if you're considering migrating your website to your own hosting account. I can clarify what that means for your continued costs (themes, plugins, etc) and recommend a few hosting services that I trust implicitly.
