Wait for the Second Offer

Seasoned negotiati9ons know that you should never say yes to the first offer (or counter-offer) because it automatically triggers two thoughts in hindsight in the other person’s mind: I could have done better or something must be wrong.
Never take the first offer. Even if the first offer is reasonable, don’t take it.
First, it makes you look overly eager, which gives the other side a greater sense of control. Don’t act too interested. Just giving the impression that you’re willing to walk away can do wonders for getting a better deal. Always play the reluctant buyer or seller.
