When you rent, there are many costs you won't have to pay. You will not pay the many fees that go with the loan process. You will not pay the commissions (real estate agents). You will not pay the property taxes (local government). You will not pay the insurance (insurance industry). Keep reading. There are so many costs that go with homeownership that many people underestimate.
You will not pay for all the new “stuff” that will go into your new home (private businesses). You will not pay the sales tax (state and local government) on all that new “stuff” that you and/or your spouse "need." You will not pay for the weekly maintenance, constant upkeep, and improvements on that new house that will ultimately fall on you and your budget.
The federal government? They will receive much less in tax revenue, because there are fewer homes being built, worked on, and sold throughout the country. The point here is hopefully clear. There are many people pushing you into buying home because they benefit from you buying a home. Only buy a home when you are ready financially and psychologically.
