Sean,
Will makes a good point about the 25% you were told you could have from the realtor. Is it legal ?no. Does it happen frequently? yes.
Why not associate with better people who can do more with less hassle and not break the law.?
I see a lot of first timers asking questions on how to save a deal.
The best way to save some deals is to walk away and live to find another.
Take the long view and get a team put together, a team of skilled professionals so you can do this again and again.
Need help to assemble the team PM me. I can tell you how or do it for you. These people don't charge you a penny, neither do I.
The deals are out there and they will keep coming. Don't focus on just one especially if it is tainted and puts you anywhere near a dirty transaction.
This web site is public and you have just stated in a public forum something that is frowned upon by the DRE.
I disagree with Will on one point though, it is your problem here's why....
A very aggressive DRE person, not that I ever met one, could make the case that you may have performed an act which requires a license which is a violation. This is highly unlikely because the DRE is mostly a toothless one eyed watch dog that don't even bark.
But what if the agent gets in trouble and you spend hours in depositions being questioned as a witness. Its not worth it.
Do clean deals and do lots of them and you won't waste your time in court explaining things and you won't have to give the money back.
