Text messaging and email are great in their place but sometimes messages get lost in translation or the wrong tone is perceived in their brevity of form of communication. An old-fashion phone call can sometimes be the best communication option.
I find when negotiating an offer email is a quick and acceptable way to deliver the documents but it's important to talk directly to parties when giving pertinent information about the offer. Often times I present a letter from the buyer or about the buyer when submitting an offer. Sellers like to know if they are relocating, moving up or down, if they have children or something to make that name on the contract become a person or family to whom they can relate.
It is good to let the seller know how much you like their home and the positive attributes. Lately all they are hearing are negative comments, the paint color isn't right, the appliances are wrong, the counter tops need to be changed, etc. In today's market it helps to establish a rapport throughout negotiations.
No one likes to feel taken advantage of and many sellers who must sell know from the beginning it's a buyers market. It's easier to accept the inevitable when they are treated with respect and can gracefully accept the situation with some dignity. So even though our email and texts are great for quick communications we need to remember in order to make a difference in our transactions there are times we need to rely on our phones and face to face communications...
