For investment purposes, you can look at buying tenanated unit. If you can get a rental yield of 5%, it is considered as very good.
Let me know if you have any particular area or property you are keen in, I might able to help you find a tenanted unit. Please feel free to drop me an email or call me directly for further discussion.
Thanks & Best Regards
