I can go into a long detailed answer if you want but the quick answer is yes it is legal, there are multiple ways to advertise your property I have several suggestions all of which would depend if you were going to do it yourself or if you were going to utilize a REALTOR; and yes it can be listed on the MLS. I have sold over 100+ houses in San Bernardino over the last 3 years, I have a great relationship with a property management company and would be happy to go into detail with you however you are comfortable.
A longer more detailed response here, you can email me at Ryan@GlendoraRealEstate.org, you can send me a text or call me at 626 991 2156. Let me know how I can help
Thank you for your time and I look forward to hearing from you.
