Basic staging with an agent usually means they give you insight into how you should:Declutter and depersonalize by removing photos and personal itemsArrange your furniture to improve the room’s flow and make it feel biggerAdd plants, move art, or re-arrange other accessoriesFull-service staging is another option if your house needs more hands-on attention.

Look, I have no idea who Eric is, what type of person he is but I will say after a quick search I saw that he did in fact sell his company for MAJOR $$$ and that he is active in Section 8, no idea if his course is good or garbage but still felt the urge to respond because I am so tired of hearing SCAMMER, find it online to EVERY SINGLE post asking about any course. anyone who actually sells their business and nets 110 mil is NOT going to dive into Section 8 or any real estate for that matter other than fine personal residences etc.. they retire and spend it.. so I dont think so.Plus section 8 is simply not complicated its run by the Sec 8 folks in each city.. nothing magical about that.. its a tough way to go being a section 8 landlord lots of drama.
