Cancelling an offer that got accepted

[David Jesse]

My offer got accepted on a duplex that has two tenants in it. But now after receiving the lease agreements, I see that the monthly price is different from what I was told initially. 

I still have not made any deposits and the contract I signed says the following

"If Buyer determines, in Buyer's sole discretion, that

the lease(s) or terms of occupancy are not acceptable to Buyer, Buyer may terminate this Contract by delivery

of written notice of such election to Seller within 5 days after receipt of the above items from Seller, and Buyer

shall be refunded the Deposit thereby releasing Buyer and Seller from all further obligations under this Contract."

So if I write to her in an email that I want to cancel. Would that be enough to get out of the contract?
