Purchasing a home and saving money are not exclusive activities. Paying yourself through an appreciating asset is as good, and in some conditions, even better than leaving money in a savings account or investing in equity markets. You need to look into how that works. If you are serious about saving money, paying rent over the long term is not always the best option. Paying down principal as a part of a mortgage puts money back into your pocket and you also get the benefit of appreciation of the home.
There are definite benefits to renting, like flexibility and having liquidity to be able to invest quickly. So if those kind of factors are important to you, then renting might be the way to go.
