True, but your rent goes into a pit and disappears forever. At least my mortgage payments are increasing my equity in something that has a value. For me the bottom line is: you're going to pay x dollars a month for a roof over your head. Isn't it better to have a portion of those dollars go to equity?
It depends on the math of the situation and also needs to take into account how well someone saves or utilizes their spare income.
For example, in most traditional 30 year mortgages and in a high property tax state like Texas, the majority of the money you pay doesn't go towards principle. Not even close.
For a small but nice starter home, you can reasonably expect to pay around $150k in my area. If (big if...and the numbers get worse without it due to PMI and amortization) you put 20% down then the loan amount is $120k. From there with the all time low rates we have now you will still pay $90k in interest, roughly $90k in property tax, plus you would likely pay another $75k or so in repair/maintenance costs (2% of the value of the home).
The total cost of the $150k home is a little over $400k at that point. If you don't qualify for the best interest rates and/or rates fall back into a more normal range then you can add on another $70k or so to that total. Basically you are looking at dropping around $450k out of pocket to buy a home valued at $150k. That money goes into a pit and disappears forever.
Now you do have the advantage of property value increasing, but with interest rates so low at this time and the shadow inventory being held back, don't expect anything close to traditional growth in value for quite some time. When the new bubble does pop values
will fall once again. That equity you paid a 200% surcharge for will shrink.
When you rent an apartment, if you are savvy with the money you save over a home you can keep and invest the difference. It should be able to reliably come out to a value higher than that $150k in equity you have after 30 years.
Buying a house does make sense versus renting when you can get an amazing deal (you get ahead on equity), get an amazing rate on a normal deal (current amazing rates are for mostly shitty deals that will crash with the new bubble), put a significant chunk down, or finally if you pay it off sooner than 30 years.
