It is hard to respond without specifics. As a general matter, where property is in a particular state, the "in rem" laws of that state will govern foreclosure and taxes. Lawyers will use a different state for choice of law purposes, most often looking to NY law for financial transactions. A company which is domiciled in another state may feel most comfortable using the law of the state of its domicile. I always set up limited liability companies under Delaware law, as it is considered the most favorable state for corporate formation. The way to be best informed is to hire knowledgeable advisors. There is no one answer to your question.
