Real estate agents are witness to numerous unfortunate instances in which homebuyers have locked into an interest rate, but are unable to close their loans because sellers find themselves in the position of still finalizing their own deals. There are also a number of other possibilities that can cause delays, including scheduling conflicts, title and homeowner's insurance problems, and even personal conflicts. The fact is that locked-in loans expire on purchases due to a lack of coordination and communication among the parties involved. In such cases, an experienced real estate agent can anticipate and circumvent potential problems by coordinating the terms of the buyer's and seller's contracts. A detail-oriented real estate professional leaves nothing to chance.
