Please pardon my ignorance, but why wouldn't they just CALL the Realtor for more info?Realtors will be able to use the SMS in order to supply more information to someone that is looking at a house. So, say someone pulls off the side of the road and sees a house for sale, and they want more information, they simply text the keyword (Which could be anything, but the address makes the most since) to the number and receive more information.
