Here is your answers and I can write a book about them.
1) When a seller calls me in response to some marketing, do I have to tell them right off the bat that I'm a licensed agent?
Yes, absolutely and make sure on all your solicitation you put our R.E. license.
2) Do I have to state "owner/agent" on the purchase agreement if the I'm taking possession in my business name?
Yes, here is how you should state. you are purchasing for a LLC. or whatever entity and you have ownership of it and you are A realtor.
3) After I have a deal under contract and want to market it at my REIA meeting, do I have to state "owner/agent" on the flier if it's actually my LLC that has the equitable interest at that point?
yes, sir
4) As an agent, I'm not allowed to pay referral fees to non-licensed persons, but could my LLC pay referral fees to non-licensed persons for leads that might become a wholesale deal?
Do not pay referral fee to non-agent whatsoever.
let me say this...the law is not against you purchasing for profit, but it is against you not disclosing your interest......
HERE IS THE BIG ONE. be careful if you buy them in default! or in foreclosure.
Thanks for any insight you can offer.
