ents tend to increase. You need to think about the likely rate of increase in order to make a good decision about whether you should buy.

Supply and demand
Even if you've never studied economics, you know that your landlord will try to get the most they can for the property. What they get will be determined by supply and demand.

If a lot of people are moving into an area, demand will be high, and rent will go up further.

As new developments are built, supply will increase, and rental costs will not rise as much, and may even fall.

Estimating increases
Over time, inflation is a reasonable estimate of rental increases. But even if you assume that your rent will only increase at the rate of inflation (e.g. 3%), you are still looking at doubling your rent in less than 20 years.

Further, inflation may be a conservative estimate of future increases in rent, because when rents increase, they tend to increase dramatically. In many cities, rents can double in well under 10 years.
