Staging

I can not stress the importance of having a well kept place wether selling or renting out. For renting out, at least keep the place clean. Hire a cleaning service to clean the property while your tenant is at work. Staging depersonalizes a property and makes it welcoming for potential buyers, for more info on staging, see below
