Hello Doug, I am not a real estate attorney nor is this legal advice.Unless someone's state has specific laws banning contract assignments you should be fine doing the following.  

If you’re using leverage, be extra cautious with your underwriting to ensure the deal still works at today’s rates.Economic Uncertainty: Inflation, potential recessions, or shifts in demand could affect rents, vacancy rates, and property values in some markets.Increased Operating Costs: Rising insurance premiums, property taxes, and maintenance costs can cut into profit margins, particularly for buy-and-hold investments.Regulatory Risks: Some areas are increasing restrictions on landlords, particularly short-term rentals.

The restrictions vary by location, but they can impact guest satisfaction and demand.

Any legal issues I should be aware of in this situation? 

TIAOne can walk away, or file legal actions.

After a grace period of 1.5 days give another notice and mention legal action or law enforcement5.

Do I have to legally disclose to my boss that I will have my sales agent license and have a brokerage sponsor that is someone different outside the MF development company?

I remember a buddy who once represented a client in the Santa Cruz Mountains.. this client turned an old barn into a shared art studio and invited local artists to rent the space, which ended up boosting inccome in ways they never imagined.The Redwood market can be tricky because of environmental restrictions, zoning quirks, and limited inventory.

I am wondering if anyone has ever taken legal action against property managers, and if they think we have a potential case? 

I think new builds don't really work from an ROI standpoint, but if you can find properties that have easy ADU conversions then the value might be there.I'm in MA and we just made ADUs legal by right, so I'm looking into the best ways to add value using them.
