You can have your agent call and verify. REO agents work under very strict guidelines. Listing agents are required to present all offers to seller (unless seller has specified in writing that they don't want to see offers of xxx criteria). So chances are your offer was presented, as the REO agent would have a lot to lose if they didn't adhere to guidelines! I would double check with your agent though who should help answer your questions and ease your concerns.
Unfortunately now some buyers are losing out on deals with cash investor competition. Banks and other sellers are willing to accept cash offers even if they're lower, due to loans being tougher to perform on, and cash being a better bet.
But keep trying. See properties as soon as they come on the market and submit offers quickly! You will get something. If you need any help, feel free to contact me.
