Unless the buyer who makes an offer on your flat/home has the resources to qualify for a mortgage, you may not really have a sale.

If possible, try to determine a buyer’s financial status before signing the contract. Ask the following:

1. Has the buyer been prequalified or preapproved (even better) for a mortgage? Such buyers will be in a much better position to obtain a mortgage promptly.
2. Does the buyer have enough money to make a downpayment and cover transactional costs?
3. Is the buyer’s income sufficient to afford your home?
4. Does your buyer have good credit?
5. Does the buyer have too much debt? If a buyer owes a great deal on car payments, credit cards, etc., he or she may not qualify for a mortgage.
