Hi Steve..
It really depends how well you know the country,its people and culture.. If not very well then I would advise not starting a business at this time.. As you may know you can only own 40% of the business enterprise in this country so you will need a Filipino partner to take on the burden of owning the other 60%!!
Im not sure what the capital return estimate is for a condo purchased by a developer and then rented out but Im sure its not that attractive.. There are some really interesting and eye opening posts on condos in this forum so please do a quick search and read up on those threads..
I own 18 units in Cavite which I built and rent myself.. ROI is pretty damned good (about 7 years) and it usually provides a pretty good income for me and my family here in Bohol so no complaints..
Talking of Bohol.. Great place to live and really not that far from Cebu..
BTW.. I lived in Sucat Paranaque for 3 years although not sure I could live there again after living here in the countryside..
Any way.. Wish you the best,whatever you decide!!

Cheers,

Fred.
