Ignore "affordability" and focus on "fair value" - why pay a $1 million just because one can "afford" it when the property is worth only $750,000.00? Helps you value property consistently and objectively using five critical parameters: 1. Return on Investment - how much money you ought to receive for the money you pump in as deposits and top-up - factors in mortgage rate changes 2. Value your property based on market size - how many buyers/sellers are competing with you - translated into rental returns - including periodic rental increases 3. Calculate the full income/benefits of your property based on tenure - the longer the tenure, the more overall income - but how long a tenure (hint - not the 99 years) 4. Factor in your risk appetite - which changes with time - from marriage, with children, empty nest/retirement 5. Finally, don't forget the time value of money - a dollar today is worth less in 10 or even 5 years hence - determine this now, today before you sign on the dotted line. The handbook also helps you to empirically factor in and trade off subjective elements such as (for example): home near office vs. near shopping, transport and other amenities; proximity to schools vs. grandparents; good facing/feng shui vs. price; and other attributes that you prefer. A must-read book before committing to buy/sell/hold property worth hundreds of thousands and even millions of dollars.
