I am happy to provide insight as I work extensively with foreign national investors in the US.

If you are "doing business" in CA, the LLC should register in CA as either a resident LLC or a foreign LLC. 

Let’s connect sometime and exchange ideas!

I now monitor the owner's equity, return on investment, and other factors and then proactively reach out when they are ripe for selling, exchanging, or adding doors.

While I don’t suggest that the smaller type investor purchase and utilize “exotic” vehicles like foreign asset protection trusts, family limited partnerships with outside controls, or Byzantine or convoluted maze of ownership entities, the more simple strategies of using Series LLCs, self directed retirement plans, and paying off their home mortgage to the extent of the Federal BK homestead exemptions can insure that a plaintiff attorney never even considers going after them.  

Otherwise you could be wasting your time.I have clients from CA and NY do exchanges in GA and other states.

If no consideration is being exchanged, then all you would need is exempt stamps for State and county. 

My real estate journey began in 2010 with a three-family property that I lived in, renovated, and eventually turned into a profitable rental before selling it via a 1031 exchange to purchase a short-term rental.My current goal is to acquire my first multifamily property using private lending by Q1 2025 and grow my portfolio using the BRRR strategy.A question for the community: What’s been your most effective way to connect with private lenders for small multifamily properties?

.- If I use a 1031 Exchange, does the next property also have to be a duplex?

The "cash-for-equity" program from QuickLoans appears to be a shared-equity or deferred repayment model, where you receive upfront cash in exchange for giving up a portion of your future equity.
