Im late.
DUDE, GD brokers are the most open.
Don't you dare counter only 10k.
Hit 10x, 50k.
They will go back and forth with buyer until deal is done.
Buyer is not shying away when they are in contact with broker. GD brokers are very professional they will make sure buyer makes another offer and present it to you.
Also 5k opening offer from broker is a lot.
Here's how it goes down with GD broker.
Broker: My name is xx I am a broker at GD etc.... I have a buyer who would like to offer $500 for xxx.com. Is this domain for sale, what is your asking price?
me: Hello, we can sell $5,000 buyer pays commission.
Broker: I shared the info with buyer, their maximum budget is $1000. You will net $800 at this price.
me: let buyer know we are willing to close at $2500, commission included.
Broker: client advised that their final offer is $1500. They are able to pay today but will be moving on if this does not work. You will net $1200.
If buyer refuses 5k and broker offers $1000, don't drop to 2.5k it's a mistake, drop to 4 or 4.5k and see the answer.
If broker says buyer is about to leave the boat then stop messing around and take the money if you are happy with it.
