Seems like provisions have been discussed for dual citizens or people with legal residency even if they have citizenship in some of these countries.   

The Dual Income StreamOne of the primary attractions of investing in a duplex is the dual income potential.

You can never tell if the dual agent is trying to collect both commissions, ensure the sale closes, or get your offer to collapse so they can accept a better offer they have as a backup.

This dual income stream can help offset your mortgage and other expenses, making it easier to cover costs and potentially turn a profit sooner than with a single-family home.

I treated the buyer like a customer, no dual agency allowed here. 

Looking to be  a dual agent and licensed in PA  as well but need to sign up with a broker first.

Dual agency isn't legal in Florida so I can't get the listing agent to submit an offer for me.

And with rentals, the dual advantage of tenants paying down the mortgage and the property appreciating is hard to ignore.On the topic of rentals, having a tenant basically translates to someone else covering your mortgage.

Either you are a buyer acting as a Principal (legal and ethical according to NAR, State, as well as Federal Law).Or you can take the advice of the unlearned, and act as a "undisclosed DUAL Agent" which is what he is proposing... and open yourself up to claims of misrepresentation.What @Brent "Kumbaya"  Coombs is proposing is clearly illegal.  

I grew up in Belize in the '80s and hold dual citizenship BZE/US.
