And let me venture a little bit out on a limb here. Even assuming your agent had acted as she said she was going to, I really don't agree with that strategy. (Some other agents probably will disagree with me, and that's fine.)
If you wanted to make an offer, just go ahead and make it. First, I wouldn't consider an offer of $610,000 on a $650,000 house "lowball." Or even a somewhat lower offer. That's 94% of the asking price. An agent who wades into the muck and asks the listing agent whether the owners would accept a "lowball" offer when that offer is 94% of the listing price may be setting their clients up for failure. "Lowball" is a very squishy, uncertain term.
Second, sellers react differently when an offer is in front of them. First, price isn't everything. The terms count, too. And the solidness of the offer and the potential buyer make a difference. Those sellers might be better off accepting a solid offer of $600,000 on their house (buyer putting 20% down, a $10,000 earnest money deposit, not contingent on the sale of another property) than a weak offer of $630,000 (buyer trying for 10% down, a $2,000 earnest money deposit, contingent on the sale of another property), Asking a buyer whether they would accept an offer, without the offer actually being in front of them, doesn't count for much, one way or the other.
And there's room for hanky-panky with all these oral back-and-forths. You can easily end up with the seller negotiating against himself....lowering the price several times without an offer ever being made. Or, conversely, raising your offer several times without the seller ever actually receiving an offer.
Customs vary across the country. But, really, an offer has to be in black and white to be properly evaluated.
Hope that helps.
Obviously no one can sign your name to a contract. That is forgery, plain and simple.
If the first contract was signed by you nothing can be changed above your signature either. This isn'r an ethical question it is a legal question and you should report your suspicion to the manager/broker at this agent office and the state level real estate commissioner.
No, we haven't spoken to the listing agent. What consequences would it have? We'd like to see the offer made on our behalf but if the signatures are forged (as we think they are) we don't want to be responsible for someone losing their job.
How do you know it was presented and/or rejected? All transactions have to be in writing.
Have you talked to the agent selling the property?
Absolutely illegal! She forged your signature. If you have substantial information about what transpired, I recommend that you contact her broker and possibly the board that she is a member of. This is most definitely not common practice and should be reported to keep agents that act illegally off the streets!
Best of luck to you,
