In many cases when purchasing a property, the purchaser will not yet have the appropriate funds to pay for the property at the time when the contracts are signed. This does not mean, however, that the contract cannot go ahead as planned, but merely that an extra clause pertaining to finance approval should be written into the contract. This clause for finance approval basically means that the sale will go ahead as long as the purchaser obtains the finance to do so within the allotted time, usually within 30 days; however the amount of time given is purely up to the parties involved. If the purchaser does not manage to get their finance approved within the given time, then the contract is annulled.
