1. 查租約，一般如果用了標準租約，會有24小時 notice clause let you in the property.
2. 沒有租約，consult a lawyer. Doesn't have to hire him but use the free consultation to find out if you have good chance. And you can pay minimun to have him write a simple letter to state your rights and consequencese.
3. Who is your buyer agent? The buyers agent should represent your interest in this case. If you used listing agent as due agent, he/she still is legally bound to represent your interest otherwise he/she conducted the business illegally.
