If one were to invest $200,000 (borrowing $500,000) to purchase a $700,000 property for example, a simple 10% rise in property price a year would translate into about a 21% return on the original investment, net of interest expense assumed at 5.5% p.a..

• 举例来说，一个人如果出资20万，再借贷50万元购买一个售价70 万元的房地产，只要房地产价格在一年之中上涨10%25，他从20万元投资中所取得的回报就有约21%25之多，这是扣掉利息成本（假设年利率 为5.；5%25）后算出的。
