At the current market value, buyers would generally borrow about $2.5 billion and put up roughly $1 billion in equity.

These loans let them skirt co-op board rules that mandate how much money a buyer can borrow.

In the most exclusive Manhattan buildings, the rules say a buyer cannot borrow any money at all.

With a fixed-rate mortgage, a buyer borrows money at an interest rate that remains unchanged for the life of the loan.

Under this plan, a buyer borrows half of the purchase price and occupies a unit (average full price about $180,000).

The other half of the price would be dormant for five years, after which the buyer would borrow the remainder.

These buyers generally borrow money for purchases based on a company's ability to generate regular income.

The league prefers that buyers put up cash and borrow against stocks.

Then, the average first-time buyer was borrowing 90 per cent of the price of his house, which meant that any fall would leave him underwater.

The Government says that buyers must not borrow money to pay for points from the same bank that has given them their mortgage.
