By listing it as such, you can have your realtor advertise on different websites that attract that type of sale. At the end of the day, if they are good tenants, and it makes sense for a new buyer financially, then it can happen. Also, try joining groups like South Jersey Investors. They can be a great source of knowledge. Lastly, 55+ is harder to sell (and to an investor specifically) than a traditional type of property, so it might take a bit more work.
