I bought a place down there and am partially snowbirding this winter, commuting for work.
Good deals generally, but keep in mind the places where the best deals exist may not be where you actually want to live. The place I got in Scottsdale is probably %40 down from it's highs, in a great community and development. You can get better deals and cheaper places elsewhere, but it is hit and miss as far as the type of neighborhood you'll be in.
Taxes are reasonable in Arizona, no special non-resident taxes. Really no Canadian tax implications if it is for personal use (not rented)--there is a question on our tax returns about if you have greater than $100k foreign investment, but it is informational and does not affect your taxes. My condo fees in a well run community are about $230. Not that outrageous.
A good website for condos is
scottsdalecondomania.com and for vegas
lasvegascondomania.com.
Westjet does 12 flights a week now through the winter out of Calgary to Pheonix, and flies there year round now, and 3 hours gate to gate.
Buying and renting an investment property has a number of complexities compared to doing it in Canada as a Canadian---it is possible, but a bunch of extra issues revolving around taxes and potentially working illegally in the US make it challenging. I'll have to look into Eric Vails info, that might be a better way to go.
I also know a good realtor down there if anyone needs one, PM me if you would like.
