How long should I wait to make another offer?

There is no set rule for how long you should wait between making offers, but it can be useful to leave at least a day. This gives the seller a chance to sit on your offer and consider the options.

Does the seller have to provide a reason for rejecting an offer?

No, the seller doesn’t have to provide a reason for rejecting an offer, but it can be helpful for both parties if a reason is provided. If the reason for rejection can be addressed by the buyer, then the sale could still go ahead.

Can an offer be accepted once rejected?

Yes, there is a possibility that the seller could change their mind and decide to accept your offer after all. This is why it can be useful to give it some time between offers.
