It is not uncommon to have weak performers working some aspect of a deal. These weak ones have to be monitored constantly to insure they get their job done.
You may have to take responsibility for called the lender and every other person who is not doing their job and ask them to step on the gas and get the deal closed. If there is a missing component you may have to supply it. Every day is solution day when your deal is under contract.
If you're not in a contract and don't have a Realtor you are working with right now, I'm here to help. If you are working with a Realtor they should be able to help you. My office is located in Federal Way and I specialize in Tacoma, fife, and Federal Way.
