I sent a flyer to every Real Estate office in my area. Who knew there were so many. I wouldn't say it was the best money spent in terms of return, but I have gotten a few calls. The problem is, the calls are typically Friday afternoon to remove mold, mildew, gutter streaks, etc, in preparation for a Saturday morning open house. Oh yeah, don't leave any streaks on the freshly cleaned windows either. I haven't gotten a call from a homeowner where I have had time to do a proper assessment and try to upsell any other services. They are always in a rush to "make it go away" and sell the house.
Because I am new and I NEED every job, I will probably send realtor flyers out again in the Spring. But, when I grow my business a little more I will stop and begin targeting only the Property Management companies. The results so far have been lack luster, but at this point it is still a paying job that gets me more experience, which is a good thing IMO.
