Prosper is a great community, but your right, you will not see many homes for lease in comparison to McKinney.
Prosper typically is a higher end market, so if you want a high end investment property it might work for you. I might suggest purchasing a couple of less expensive homes in a community that has a strong demand for rental property.
You will lease them quickly, keep them occupied and rental checks flowing. When you decide to turn or sell the property it will be picked up quickly by investors.
In summary, investment properties take many forms; but if you want rental properties to generate income then pick a community that has a proven track record for that.
Best of luck and call us if we can help,
