Hi I am Chris Bilborough, 5,128 people bought Investment properties through my company worth almost $750 Million in total, today they are worth over $2 Billion. My company pioneered systems and techniques allowing us to sell 200 properies per month with salespeople that regularly sold more than 20 Properties per month each.
Those properties only cost $46 per week (average) to keep and the deposit was $1000 and they went up $160,000 (average) in 10 years, the total cost to the people would have been less than $20,000 to keep over that time.
The clients payed $20,000 over 10 years to get $160,000 Gross Profit, that is an 800% Return or 80% per annum on the cost expended to keep them, that is $160,000 they would never have had if they did not invest. Not bad when the average Superannuation Payout is less than $100,000 from a lifetime of work.
The best example of a property that someone bought from me that I have found so far was in a suburb of Brisbane, Inala, for $39,950 in 1998 and that sold for $195,000 in 2008. That is a 500% increase in 10 years or 50% PA on average.
P.S.
I am truly sorry for those that sold and missed out on the profits, or indeed lost money. They should sue Jenman, Herriot and others for manipulating the supply and demand and telling them to sell instead of holding on to them at the worst possible time.
