For real estate, Hipflat and DD property. Hipflat really only works for buying and selling though, good to research condos but most of the listings are expired or no longer available. DD property works the best in my opinion, buying/selling or renting though their map feature isn't very accurate.
As someone whos just about never wrong, I'm really surprised by this. I'm always willing to admit when I'm wrong though, I'd have to find my notes and I can almost guarantee it was a rule at some point. But if you guys (who I trust) say it's not, then I guess it isn't.
Actually didn't know that, thought it was just a foreigner issue. I know Vietnam made a lot of laws after the war to stop prostitution with the US soldiers.
