@Alicia Herring,
I think I heard a statistic that over 95% of people who sell their house do so by listing with a realtor. I would also say that the higher the value of the house, the more that number goes up. Based on that, the likelihood of finding a wholesale deal (let alone consistent deals) in this market is extremely low. I think the way that you would be the front-runner to close up a wholesale deal in this market would be to be known by the owners.
Remember, there are many ways to make money in real estate. You have a nice gig going. The owners in this market should know you and what you have to offer. If I were sending them a mailing, I would market your current services as well as letting them know that you can also help them if they find themselves in a difficult situation where they need to sell fast (of course, better words would be... better).
If I were in your shoes, having the entrepreneurial spirit, a good business model, and looking to expand, I would look for ways to expand my market (can you offer these services to a broader market?) and grow my business (can you hire people to help with administration, marketing, etc.?)
I would also take the opportunity to look for more lucrative ventures, like wholesaling. If you want to go this path, how can you work on it without negatively impacting your current business? If you're out driving a fair bit, learn to D4D (drive for deals). Keep an eye out for the right type of property that might be a good wholesale opportunity. As you work with other RE professionals and investors, let them know what you're doing. Build your network.
Thinking of those properties, they sound like good vacation rentals. I don't know the area, of course, and that's something that would require owning the property, but it's something to consider. Perhaps partnering with someone who has the funds where you can take on the decorating and stuff.
It's all about creative thinking.
Good luck!
