Steve..
Ive said it before and I`ll say it again..Do a 6 month mock run..Rent a place first!!
Get a feel for the area and hopefully in that time you will know if its for you..Or not!
Also gives you time to to check out property,land etc on your own terms and time to really learn about your personal cost of living etc..
Forums and the internet are good for certain things...Boots here on the ground for a good few months gives you real information custom fit for YOU and the Mrs!
It`s what you really need to do IMO when the time is right..
As youknow..Here to help when or if you decide that Bohol is really an area where you want to at least give it a go.
