Buying and selling website

[Daniel Fisher]

So many times when I check wholesalers/rehabbers websites I see they have links to sell properties and to buy properties on the same website. Or there are properties listed for sale on the website.
Isn't this a turnoff for potential sellers when they see what these properties are selling for? Or is this a non issue?
I am looking to use a website for buying and to sell properties. Would you use one website or keep them separate?
