Buy/Sell Mobile Homes...2 websites/facebook?

[Samson Taylor]

Good afternoon everyone. I'm a newbie in the realm of real estate investing. I'm looking to buy and sell mobile homes and progress from there. My question is, do investors, investing companies and so forth who buy and sell, create 2 different web presence names so they don't have buyers and sellers seeing the "other" side of the business?

Example www.Webuyyy.com (marked up homes) vs www.WeSellll.com (buy homes for cheap). Same example applies for the facebook page(s)

What's the common practice? Create a site where you just buy or sell homes and place an email address for customers looking to do the opposite of what the site specializes in?
