Can I help a buyer in another city in Texas like Dallas? She is approved for a home loan. She has a list of homes in the area she wants to see also I can search I am not part of that MLS but wondering If I can show her the homes? Can I use my Supra key to unlock doors in another city like Dallas I am part of Houston HAR MLS. How does the pay work too is it the same? send contract to my broker for a CDA and give to the title co in Dallas?
