People in their 20s and in their 30s are usually looking to either find a place to live that they can call their own or try to rent out a place to live in for a while. However for a huge majority of the people buying a house is usually not an option. Buying a house is a huge investment and a very expensive one as well. For many people in this age bracket buying a house might not be a financial possibility, the idea of putting in that much money in to a mortgage will end up using a lot more money than you might be prepared to spend. On top of that the amount you will pay back on the loan will actually be a lot higher than what the house actually would cost you. Other than that, your 20s and 30s is usually a time where you might not want to settle down in a single area. At this age you might get different types of job and work offers from different areas and maybe even different countries. It might not be the best idea to be tied down to a single area and be unable to leave if some opportunity comes up.
For these reasons you might just want to think about either buying or renting a condominium instead. If you live in Canada you will find that there are a great many condominium projects going on, like the Daniels City Centre Mississauga for example. Both renting and buying a condo in a condominium will lead to a much lower amount of money being spent. With a condominium you will also be able to have access to a lot of different amenities and facilities as well, which would end up costing you a huge amount if you tried installing them in a house.
