A question about etiquette

[Alex Verdugo]

So I have a question about etiquette. I met a realtor at a local meet up and he told me about a property. The property it self looks like it's going to need quite a bit of work just from the outside appearances. I've messaged him with a few questions about the property, rents, why they're selling, etc, and have yet to receive a response. Its been two days since the first message where he replied that he would get the answers to my questions. My etiquette question is this: how long should I wait to receive a response to my questions or should I just sidestep the realtor and ask my questions directly from the seller? I have no idea if the realtor has another buyer, already sold the property or is just ignoring me. My thoughts are that if the realtor isn't responding, that I should be able to go directly to the seller, find answers and make a deal directly with the seller. I'm still new and not sure what real estate investor/ realtor rules/ guidelines/ practices dictate. Thanks for helping with your opinions.
