My wife and I are considering buying a home soon - some of the major reasons are personal, such as being able to perform repairs and updates to the property, and having the security and peace of mind of owning our own property.

But one thing that I'm a little nebulous on as a benefit is the thing that people always quote at me as a benefit to buying a home - Equity.

My basic understanding is that Equity is "How much 'loan' you've paid off on a home", and that by buying a home, we can store up equity for the future if we want to move to another home, or to borrow against it in case of emergencies (a "home equity loan").

Do I understand the benefits of home equity correctly? Or is there something I'm missing from this?

Broadly-speaking, equity just refers to (the value of) what you own, after deducting what you owe.

The accounting equation is: Assets - Liabilities = Equity.

So if you have $100k in cash (and no loans) and you borrow $200k to buy a $300k property, your equity before and after the purchase is the same. You started with $100k equity and you ended with $300k - $200k = $100k equity.

Suppose you get a bill for $10k.

• If you kept your original $100k in the bank and didn't buy the $300k property, you can just draw $10k from your bank account to pay for it, leaving your equity at $90k.


• If you borrowed to buy the property, you can increase your mortgage by $10k (assuming you have the appropriate redraw privileges) to pay for it, leaving your equity at $300k - $210k = $90k.

Unsurprisingly, both possibilities give you the same equity.

Loan repayments come from income. If you get $10k worth of income and pay that into your mortgage, your assets are $300k (property) + $10k (income) = $310k. So your equity is $310k - $200k = $110k. If you didn't take out the loan, adding the $10k income to your $100k cash in the bank nets you $110k equity.

Now, if your property appreciates in value, say from $300 to $350k, your asset has now increased in value. Ignoring income, loan repayments and interest for simplicity, your equity has now increased: $350k - $200k = $150k. The increase in equity comes from your investment. If your house price depreciates, your equity drops by a corresponding amount. In the other scenario, had you invested your cash into shares and the shares appreciated by $50k, your equity would also have increased to $150k.

Earning bank interest works the same way to increase your equity, and paying mortgage interest does what you'd expect to decrease your equity.

You ask:

What does “Home Equity” do for me?

It does exactly the same for you as "cash" equity does, except that cash at bank tends to be easier to withdraw. You can draw on your home equity only if your mortgage arrangements let you increase your loan.

But once you've taken on a mortgage, the 'value' of your house becomes something of a nebulous figure. You can't easily give the bank a third of the bricks to exchange for $100k. And what you paid for the house may not be what someone else might want to pay. By playing with the asset figure (the house price as valued by the bank), the bank effectively plays with your equity figure. If they say they only recognise $250k of your house price, then your equity becomes $250k - $200k = $50k, instead of the $100k cash you had before buying the house.

Conversely, if the bank says your house is worth $400k, then your equity becomes $400k - $200k = $200k. Note that if you did borrow that additional $200k ('unlocking' the equity in your home), you now have a loan of $400k. Should the bank require it back, you'd need to sell your house. If you can't get a price of at least $400k clear of fees, then you'd have negative equity. Say you sold the house at $350k. Your assets are now $350k, but your liability is still at $400k, so your equity is $350k - $400k = -$50k. In this situation, you owe the bank money and have nothing with which to repay. This is a bad position to be in.

Whether it makes sense to buy a house - that depends on your situation and your own disposition. But buying a house doesn't increase your equity. It just changes it from cash to a more nebulous form of (house price minus loan amount).

Do I understand the benefits of home equity correctly?

Sort of - equity is essentially the value of the home minus what you owe on it. So if you make a mortgage payment that pays off the principal by $100, then you increase your equity by $100. When you sell your home, the amount that you sell the home for less the amount that you owe is your remaining equity. So if the value of the house has gone up since you bought it, then you'll have some additional equity over what you've paid off.

The problem is the rest of the payment is in interest that has no benefit to you (other than possibly a tax deduction). So in a sense, owning a home lets you pay yourself money by paying down the loan and increasing equity, but it costs you in interest.

This comes up a lot when people are considering renting or purchasing, and "equity" in the home is given as a "pro" of home buying. The other answers are correct in explaining what it technically means, but in simple month-to-month terms, the benefit is pretty simple.

Say you are paying $1000 in rent. That money is gone forever. It's 100% an expense that covers the cost of the property, taxes, maintenance, etc. Now when you have a $1000 house payment, you're also paying "fees" that you will never see again (taxes, insurance, and of course interest), but a portion of that monthly bill goes towards "equity" in the home. It pays off your loan balance, and when you sell, you get that money back (simplifying and assuming you sell for the same price you purchased). So, in this case of comparing to rent, equity means that you will eventually get back some of the money you are paying every month rather than it being a 100% expense.

This also helps when comparing the payments between a 15yr and a 30yr mortgage. Knowing that every payment made on a 15yr loan helps me build a much higher percentage of equity makes me feel a lot better about it even though in simple terms, the 15yr payment is "more expensive".

Equity is the value available to you out of the asset you own. If you owe on a house then you pay interest for borrowing money against the assets equity.

The equity is part of your net worth. The asset (house) adds to your net worth. The mortgage or home equity loan subtracts from your net worth. The more you borrow against the equity in your asset, the less equity remains in that asset. The cost for using the equity in your asset is called interest and is typically based on a percent of what you borrowed (remaining balance of your loan). Once the loan is paid off, you no longer get charged interest.

The equity can grow or shrink depending on the asset type. Appreciation of the asset (growth of it's value over time) will increase your equity. Typically, traditional built homes and the land on which they set will appreciate. If the asset decreases in value (mobile home, cars, etc.) you'll lose equity over time. You can also lose value by not maintaining your asset.

So to answer your question, Home Equity can provide the following:
- You can borrow against the equity (paying interest to do so) for money to do other things with.
- You can use it as a means of savings. If you owe nothing and your asset appreciates, then you continue to grow your net worth. You will need to sell your asset to access that savings (which means it's harder to spend because the money is not readily available).

Banks want you to borrow against your home because it makes them money on the interest. Look at the amortization table to understand that the interest charged is more substantial at the beginning and principal (remaining balance) reduction is less. As the loan amount reduces, more of your payment will be applied to principal reduction and less on interest. Therefore banks make more at the start of the loan. There are a lot of things to consider before using the equity in your home.
