Just as it is important to know which clauses not to agree to in an offer to purchase, it is also critical to know which clauses you should insist on and understand why these clauses are there to protect you as a buyer.
Signing an Offer to Purchase can be really stressful and too many times buyers sign because they feel under pressure to make an offer on the spot - only to realise that they are not happy with what they signed. And then it is very difficult to cancel the deal, particularly if they have paid a deposit!
