Remove all contingency. Close it anytime. At beginning, the listing agent said we have a very strong offer. After a few days, she told us the buyer chose the neighbor's offer. From listing agent, seems the neighbor are not offering higher price, just be picked by buyer. She first told us it because we are not personally at the house (遠程房)but we have waived everything and can close the house anytime and can pay higher deposit if needed. Then she told us the neighbors been choosing is because they are neighbors. Ok. Then, it's buyer's choice. By the way, we used listing agents as our buyers agent.
