Sellers agents not responding

[Yuvaraj Vimawala]

Hello, I am an investor who is interested in out of town multi family investments. Recently analyzed 2-3 Fort Worth deals, liked the numbers and started discussing with the sellers agents. Here are my challenges: 1. Sellers agents talk to me once or twice and stop responding (I have not asked anything offensive) 2. Sellers agents do not share any info (rent rolls, P&L statements etc.) 3. Tried placing offers and contacting via a buyer agent as well - no luck. I have a suspicion that some good deals like these, sellers agents stop responding after they get 1-2 good offers or probably favor their network. I know they are obliged to share any legal offer with their clients, but if they don't hear my offer, they don't have to. I may be paranoid.. so looking for advice from experts here. Am I doing /or not doing something I am not supposed to? I am following the advice from popular books on real estate, where I am supposed to ask for the right info before making an offer.
