Because I didn't want to give up my American car, 6 months at a time has been how I lived for the last 2 years. So yes, 6 months at a time is doable. It depends on your relationship with the property owner and how secure you feel. I have had no problem, and trust my housekeeper completely. At this point I rent for a year at a time.
No one has ever asked me for copies of tickets when I have traveled in and out of the country. Their interest has been solely in my passport and visa.
