Yes, here in ShiJr it is cheap. There are places in FuJi Shan Zhuang/OuZhou Lian Bang here where I live on Da Jian Shan (the big mountain nearby HsinTaiWu Rd, opposite side of the valley from Lotus Hill) that are total expat paradises with central air, 3 to 4 floors and some roof decks, fully furnished, French fabric on the walls, free parking or your own private garage, BIG western sized oven for baking, two door refrigerator with ice cube and water dispenser, huge gorgeous pool and tennis and basketball courts in the community and all of this up in the mountains with a view of the entire city of Taipei (cooler up here in the Summer too with cleaner air) and on most days I can see all the way to LinKou in one direction and Keelung in the other direction. All of this with heated floors for your winter comfort as well as multiple balconies. What else did I forget, the furniture is quite nice and the walls have padding and fabric on them (I think some kind of European thing?). This place also has excellent insulation. I turn off central air, leave the house and come back 6 hours late and the place is still cool. Anyway, I have heard that the rental price of these town houses are now down to between NT$35,000 ~ NT$45,000 for 50-70 pings.
Four or five years ago, we rented here for NT$60,000 for a lower unit with garage, the upper units went for $70,000 but now they are all the same price.
You can also rent a whole house although with all of the luxuries as mentioned about but with access to the same pool and also with a yard and garage. I rented a 90 ping house that was only less than 10 years old and had never been lived in for NT$35,000.
If you want to live outside of Taipei I would suggest you buy a car. With a car it takes me only 20-25 minutes to get to Warner Village, 15-20 minutes to Neihu and only about 30 minutes for any other place in Taipei via the three highways that meet in ShiJr.
