Should you mass text all of your phone contacts to let them know you buy houses?

[Seth Larson]

I hired a laborer for a day and we got to talking about what I do (wholesaling, rehabbing) and it led to him letting me know hes selling two houses off market, one of which im closing on in the next couple days. So now Im thinking about leveraging that kind of interaction, starting with texting all of my old contacts that have ever done that kind of work, or just any/all old contacts no matter what they do.

Im relatively new at this, about one year so I think an introduction text may be in order anyways. 

Has anyone else thought about trying to get leads from contacting construction companys or individuals that do work on houses?
