Calling "we buy houses" signs

[Zachary Haded]

I was wondering if anyone has experience calling we buy houses signs not to sell a house but to buy one. I am currently looking to purchase a property to fix and flip, or wholesale depending on how much of a discount I can get on a property. So anyways I just wanted to know if it would be a good idea to call these signs and if so what should I say? Thank you in advance.
