Longest you've gone with an empty property (for rentals)

[John Collins]

Curious, and at what price point? My highest rent property has been on the market for a while and even though I've dropped the price below market, people just haven't been coming to see it this time of year. The agents who've seen it say it's great value and has been done really nice (it's not the state or design of the place that's preventing people from moving in). 

What steps have you taken to get people in to view it, and to rent it? How much below market are you willing to go, is it worth it if it's a bare minimum positive cash flow?
