If you're less than satisfied with the results you achieve on the expat sites, you should try going native and do what the locals do and use the Chinese language websites. If you can't read Chinese, you'll need to enlist a native speaker to help you.
591 -- one of the most popular websites in Taiwan that people use to rent or to let out properties
The king of Taiwanese rental websites is 591, which has the highest web traffic and number of apartment listings of any site on the island. Right from the start you can use their map to choose where to begin your quest. Like most sites of this ilk, you can search by city, district, neighborhood, type of apartment and price range.
Each listing usually comes with a number of photos, information about furniture and amenities, maps of the apartment's location and nearby landmarks, a Q&A section, and a list of recent transactions of similar apartments in the area.
On the left menu bar next to the search results are many options to further refine the search by price, size, number of bedrooms, etc. Under listing party (經辦人選擇), select listed by owner (屋主刊登) and hit the reselect button. This way you can cut out the agent and go straight to the landlord if you want to.
