If your lower flat has been vacant for four months, it is either too high , marginal condition or a combination. I have ten units in Mount Clemens and do not really have any of my units vacant for more than 30 days unless they need extensive repairs.
I do all of my properties on Craigslist, (once in a while a sign) making sure to re post every three days and have no lack of potential tenants. Of course a good percentage of them will not pass the application process but the name of the game is to get multiple potential tenants to choose from.
Good luck.... more
