Put an offer in for a property on Monday. Got told there was another higher offer on the table and could I do better? I did (changed terms, upped price). Haven't heard back from the agent. Is it legal to play one buyer off another? What's stopping the agent going to the other party with my offer, to try to get more? It is feeling almost like a (very long, drawn out) auction to me at the moment. Wondering if I should call the agent to see what's going on or if I should just leave it with them.
