My comment was that it depends on how you come accross the deal. For example, the licensing board doesn't look too kindly on agents that market themselves as agents, get in the door as agents, earn the trust of the client or potential client, and then convince the new client or potential client to sell you the property below market value. If you are going to buy your clients property (or someone that thinks you might be their agent) then you probably need to take extra steps -- i.e., tell them what the property is worth and give them a chance to talk to an attorney or other agent before you close the deal. In some circumstances you may conflict yourself out of the deal, but most deals can move forward with proper disclosure.
If you (or your investment company) are working to find properties from people that are not your clients and you are not soliciting them as an agent then you may not need to disclose anything or you may need to simply disclose that you are an agent representing a related entity looking to buy your own investments. There are many other combinations of possible factual situations.
This is a fact intensive analysis with a handful of set rules. If you are worried about whether you should or shouldn't disclose then send me a PM and we can look at the facts and rules together.
