I contacted one of these companies - can't remember which one - just to see what happened. 3 men toured our house then one called back and said we'd get more money putting it on the market and they tried to get us to list the house with them. It seems like an ad for these investors and agents to generate leads for listings or to fish for below market deals. I never did get a 'cash offer' like they claimed. Just a big waste of my time. When a company pays a lot of money to run an ad, you have to ask yourself why? There has to be something in it for them to do this so it's a way for them to try and benefit off of you at your expense.
