CA Resident - Do I need an LLC in each state I invest in?

[Scott B.]

I'm a CA resident with properties in the Kansas City area. We currently have a Delaware Statutory Trust that holds our properties for asset protection/anonymity. All of our units are on the KS side of the border, so we have a KS Operating LLC. As we're looking at expanding across the river into MO the initial plan we were given was to create a MO Operating LLC as well, incurring another $800/yr feee to CA. Does that sound right? Couldn't we just register the KS LLC as a foreign entity doing business in MO and avoid a second LLC?

Just curious if that's completely unreasonable before I push back on our team.
