I'd like to place multiple offers on multiple properties, but I can only buy one. Of course, I can simply withdraw my other offers as soon as one gets accepted. The common law postal rule could get me in trouble, but I can negate this by putting this on offer. What I am nervous about is two offers being accepted simultaneously, e.g. agent rings me advise me of acceptance and while I'm on the phone call another sends an sms text message advising acceptance... them I'm stuck with two legally binding contracts! Any advice of what I could do? Maybe a clause in my offer advising something along the lines of I'm placing multiple offers and can only buy the first accepted one? How would I word this? Any advice?
