How to get commercial mortgage via new company

[Kevin Melanson]

I plan to buy a single family home in Austin and, per the city's STR rules, it has to be either an owner-occupied or commercial residence. If the current plan is to open an LLC to apply for a commercial mortgage loan, how is this possible with a newly created company?*
*the belief is that I will have to co-sign (which keeps me personally liable; maybe able to refi after 1 year of that?)

Will you please help with your thoughts on this topic?
