Alright, let me paint a couple of scenarios for you, because if you don't own your place you're either renting or sponging off of your friends or relatives until you've saved enough money for your own place (and I don't know of too many parents who would let you live with them for ten years rent-free while you saved up enough money to buy your first home):
Scenario 1: You've managed to get together the deposit money for a 7-800 sq. ft. 2 bedroom apartment (yes, you needed decent credit to do it in the first place). Your rent is $1200/month and you're annual net monthly income is $2500. After utilities, food, rent, car insurance, gas, maybe a car payment...you're pretty much scraping by. So, you get a roommate to move in and pay half the rent and utilities, so y0ou're able to save about $600/month towards your house you intend to eventually buy. How many years do you think that will take?
Scenario 2: You've managed to scrape together the 5-10% minimum down payment to buy your first starter home. It's a decent 1600 sq. ft, 3 bedroom 2-bath home. Pretty standard. Homes like this in your area are going for for around $198k, but you found a good deal and picked one up at a steal for $183k because the owners were desperate and just needed to get out. You got a good interest rate on your mortgage and your monthly payment is around $1000. After utilities, car and homeowners insurance, mortgage payment, food and gas and maybe a car payment, you still have several hundred per month that you can put in the bank. Being smart, you get yourself a roommate and get them paying at least half if not more of your mortgage and utilities and you're able to even save more money per month.
Okay, so, two scenarios. So, let's look at each of them a little more closely. When you rent, your money is gone. Every month, you are just giving your money away. It's gone. Forever. In someone else's pocket. So, in Scenario 1, you are essentially bleeding money every month. Money that you could be using to accomplish your future goals. When you own, that money goes back into the equity of the property that you own. Since you found such a great deal on your house in Scenario 2, you already have instant equity in your home to the tune of $15k worth of value if you were to sell and able to get full price. You were also smart enough to pick a home that was in a neighborhood that's appreciating, so over time your equity will continue to grow in this house while you may your mortgage payments every month. After three years, you decide to sell and get enough to walk away with $30-40k in profit because the place appreciated over time. Now you have money that you can use to upgrade to a better, bigger house, which you can afford because you've worked hard and gotten raises and promotions and now make more money and can afford nicer things.
There are some other bonuses to having your own house. You can paint and decorate the interior however you damn well please. The exterior you may have some limitations with depending on your neighborhood covenants, but still...you have some ability to make changes. You are not going to have that same freedom in an apartment, quite often. Also, in your own house, you can play your stereo as loud as you want at any hour of the night or day. You also don't have to deal with noisy neighbors, conversely, stomping on the ceiling or blaring THEIR stereos. In an apartment, you'll always have that to contend with.
So, knowing that living in an apartment, aside from the limited freedom to do what you want with the place and the noisy neighbors, you will literally be giving your money away never to return, why would you ever do so? I could see if you were new to a city and wanted to just look around and get to know the town so you could decide which part of the city you wanted to live in eventually or if you weren't sure you would be staying there permanently because maybe you were on temporary assignment by your company or something. Otherwise, being able to build equity and know that your money isn't just completely going to waste to line someone else's pockets on your mortgage because the principal of your payment is essentially paying yourself back for the loan on your own place that you have more freedom to do what you want to do with it makes a hell of a lot more sense.
So, go ahead and keep throwing your money away on rent if you like. Seems pretty damn silly, to me.
