A transaction system has Internet-connected partner platforms hosted by real- estate sale enterprises, displaying property for sale or rent with an Offer-Now button initiating coded instructions to display an electronic input form enabling a person to configure an offer on one of the properties, and an Internet-connected service enterprise providing the coded instructions to the partners, configured specifically to partner requirements. Upon the person activating the Offer Now button from a mobile device, a verification code is sent to the device, to be returned to verify the device, and offer input provided through the device and the electronic form is tracked to be saved as an offer for sale or rent of the specific property.
