Government should not place more restrictions on the sale of vancouver residential property to non-residents

it is an important debate. the topic is if government should place more restrictions on the sale of vancouver residential property to non-residents. and we are against it. please help me find some arguments to prove the opinion. you dont need any format. you can write in separate sentence, or you can just give me the website link that help me analyze it. maybe you should use some economic knowledge to prove. as I choose the top writer, I really hope you can give me the strong arguments.
