Unfortunately with property investment this is true in the beginning for most investors.
However, it’s a fantastic way of providing wealth, that is, if you have set things up corrrectly.
Normally in the beginning the debt level is high, but as years go by you reduce the debt, and the value increases. Also over the years you will get to retain more of the income as debt reduces.
Property is not normally a get rich quick scheme so the biggest asset you must have is patience.
The second biggest asset is having a strategy or action plan.
Remember: Failing to plan is like planning to fail.
