We needed a single page website to advertise a rental property. Rather than input the same info on multiple rental listing websites, we simply created the site with in depth details on the property and included the link in our listings.
I chose the My Resume Wordpress theme by Elegant Themes because of its straightforward and professional presentation. This responsive (mobile-friendly) theme is an excellent choice for those working with an appropriate project on a tight budget. While it is intended as an online résumé, it can easily be adapted to list a rental property online (this is a great option for an affordable vacation rental website!). It has very limited design capabilities, but what it does, it does well.
