Offer a larger option fee.
This shows your client is serious, and a large option fee is another financial incentive to buyers.
See if the lender can contact the listing agent.
If your client would like, having the lender contact the seller’s agent can offer additional assurance that the sale will close.
Consider a personal letter.
A letter from your clients explaining why they are right for the property can offer an emotional pull if done correctly. However, some listing agents warn their sellers against reading personal letters because of the potential for fair housing-related claims.
Pay for the extras.
If offering more isn’t an option, consider paying for items such as title policies, surveys, or residential service contracts.
