Come up with a business name and market everything under that name. Setup social media accounts using your business.
Dominic, very simple if that is a major concern for you and a real risk, just do not use social media to promote your real estate investment business. There are many investors who have never used social media to promote their real estate investment business. Social media is a plus, not a must.
I wish you the best!
You could always create a separate business page on social media, and when the time is right, you can always combine with your personal page.
