Here’s some considerations that I hope are helpful for you:
Have a mat outside for wiping feet, and a small rug (with non-slip backing) inside at the front door. This will help keep the property clean.
In the bathroom, remember to have toilet paper, hand-soap, and a nice towel available. No explanation needed.
Make sure that the temperature inside is pleasant. And not only for showings. The temperature should always be reasonable: too cold and pipes could burst, too warm and wood flooring could be ruined.
Go over before a showing and make sure that blinds are open and lights are on. Potential renters love a property with lots of light! And remember to go over after the showing. Not only is it best to turn the lights out (nothing says empty house than a brightly lit one in the middle of the night), but you’d be amazed how many realtors will leave a door unlocked. Or a gate open. While you’re there, do a quick sweep of the property to make sure that all is well.
But will the renters like lots of light if they’re vampires or millennials?
