For years there has been a religious like devotion to the Mortgage Income Tax Deduction (MITD) and its benefit for the home buyer. In stark economic truth it is actually bad for home buyers (twice) and great for banks. This is further proof of how stacked the economy is in favor of the banks. So the banks exploitation of society hasn’t been going on for 10 years, its been going on for over 60. Here is the mathematical and social proof.
- The MITD applies to interest only.
- It allows a home buyer to pay more in monthly interest payments because they will get some of that back as part of MITD.
- So consumers are willing to pay more interest which means they are willing to pay more for a house (because they can support a larger loan principle).
- The interest goes to the bank who profits by the uptick in interest payments.
- The buyer pays more for a house.
- The taxpayer (who is also the home buyer) pays for that payment to the bank out of their own taxes (cause tax dollars are diverted to the MITD)
Its that simple and we’ve been falling for it since the end of World War II.
Here are some numbers:
- Let’s say (without the MITD) the you have $2000 to spend on a mortgage per month you’ll buy a certain amount of house.
- If you add the MITD you can now buy about $2500 of house (assuming you have 20% tax rate, not realisitic but makes the math simple for this exercise).
- Your spend $2500 and you get $500 back with the MITD. So what happens is a person is now willing to spend 25% more on the same house because they can afford 25% more in monthly INTEREST payments. Since houses are basically bidding processes enough people compete such that the price goes up to absorb the entire deduction.
- At the end of the day the person is no better off and actually is worse off because they scrape to find the extra $500 per month and then get relief at tax time with a big check the makes them whole (losing any interest they could have earned on that $500 in the interim and possibly incurring financing charges because they needed to get that $500 cash flow somehow in the interim, lets say through credit card debt.)
- In the meantime the bank collected that $500 extra a month and they didn’t need to give it back. That came from the government (AKA the taxpayer).
- Hence the buyer gets to pay more for a house and more for his taxes overall.
So next time you brag about your mortgage income tax deduction remember you just helped make a bank wealthier at your own personal expense (both as a buyer of house who paid more than you needed to and as a taxpayer who financed it).
