Should you get a 15 or 30 Year Loan When Financing Rental Properties?

15 year loans may appear to save money over 30 year loans because of the lower interest rate, but I would much rather have the flexibility of a 30 year loan. Buying rental properties is a great investment, especially when you are able to use a mortgage to buy the properties and still get great cash flow. Many investors will get a 15 year mortgage on their rental properties, because the rates are a little lower and they can pay off the properties quicker. I use a 30 year loan when I buy my rental properties, because I get more cash flow and I have more flexibility with that extra money.

What are the advantages of a 15 year loan versus a 30 year loan?

The biggest advantage of a 15 year mortgage compared to a 30 year mortgage is the interest rate on a 15 year loan is less than a 30 year loan. The difference in rates changes daily and varies with different banks, but a 15 year loan is usually about .5 percent less than a 30 year fixed mortgage.

Some people think the biggest advantage of 15 year loans is the term of the loan; 15 years versus 30 years. But I don’t agree because you can pay a 30 year loan off early if you want too. You don’t have to make the minimum payment on a 30 year loan if you want to pay more. I used to pay off my 30 year loans early using my snowball method.

How much money does the lower rate on a 15 year loan save?

If you get a 15 year, $100,000 loan on a rental property at a 4% interest rate, the payments will be $740 a month (check out bank rate mortgage calculator for calculating mortgage payments). Over the 15 years of that loan you will pay $33,143 in interest. With a 30 year loan at 4.5% interest, the total amount paid in interest over the life of the loan will be $82,406.

On the surface it looks like you are saving almost $50,000 by getting a 15 year loan. However, you are paying interest over 30 years on one loan and over 15 years on the other, which is deceiving. The payment on a 30 year loan is only $507 a month, which is $233 less a month than the 15 year loan. If you were to take that $233 a month and put it back into the 30 year loan each month, the 30 year loan would cost $39,754 in interest and be paid off in less than 17 years. It definitely costs a little more to have the higher interest rate, but over 15 years that is only $550 each year.

Why would a 30 year loan be better than a 15 year loan?

It is true that with a 15 year loan you will pay less than a 30 year loan in interest. However, you are paying a higher payment every month on the 15 year loan. If you add up the payment savings with the 30 year loan, you save $2,796 each year and $41,940 over 15 years on your mortgage payment.

That extra money can be used for many things that will make you much more money than that $6,000 in savings. You can save up the cash flow to buy more rental properties. You can use the money to build an emergency fund. You could also pay extra to the mortgage early and if you ever need the extra money later, you can stop putting extra money into the mortgage.

Buying multiple rental properties is harder with 15 year loans

Another huge factor when considering whether to use a 15 or 30 year loan, is qualifying for more properties. When banks qualify an investor, they will look at debt to income ratios. A 15 year loan will have a higher payment and increase your monthly debt payments. The higher your loan payments are, the less cash flow you will have and it will be harder to qualify for new loans. Many banks will only count 75% of your rental income when qualifying an investor for a loan. Even if you are cash flowing with a 15 year loan, if you can only count 75% of the rental income, you may show a loss each month. If you have many rental properties showing a loss, it will be very hard to qualify for new loans.

Using a 30 year ARM (adjustable rate mortgage) versus a 15 year fixed loan

When I finance my rental properties, I use 30 year ARMs. An ARM is an adjustable rate mortgage that has a fixed interest rate for a certain amount of time. The interest rate on an ARM can adjust up or down after the fixed time period is up. My portfolio lender offers 5 and 7 year ARMs with a 30 year amortization. The rate will stay the same for the 5 or 7 year term, but can adjust after that term is up. There are limits on how much the rate can adjust each year and a ceiling that it can never go over. The great part about ARMs is they have a lower rate than a 30 year fixed rate loan and even the 15 year fixed rate loan.

If you get an ARM for your rental properties you will have an even lower payment than a 30 year fixed rate loan and save money in interest costs over a 15 year fixed rate loan. To me it is the best of both worlds.

What is and ARM less risky than you may think?

There are obviously some risks involved with an ARM, because the rate can go up after 5 or 7 years. My plan is to pay off my loans before they can adjust and I also have enough cash flow to be able to sustain a higher interest rate if I don’t pay them off. Chances are rents will increase in the time period as well. If you have enough cash flow and a plan for when rates could increase, you should have no problem with an ARM.

If you don’t have enough cash flow and your payments go up, you could get into trouble with an ARM. Negative cash flow is hard to sustain and it will be harder to qualify for loans if you have negative cash flow.

Benefit of a lower payment versus a higher payment in the future

ARMs allow a small payment in the beginning of a loan and possibly a higher payment in the future. The nice thing about the lower payment is you have more cash flow and inflation comes into play when you are investing money. If you can pay less money now and more in the future it is a good thing, because inflation will make money worth less in the future. Even though your payment might go up on an ARM; 5 or 7 years later that money will be worth less and your rents could have gone up. If you use the money you save on an ARM to invest in more rental properties or something else with a decent return, you will be way ahead than if you had paid a higher payment with the 15 or 30 year fixed loan.

On the surface, a 15 year fixed rate mortgage may seem like the best way to go. It saves money on interest over the life of the loan and has a shorter term. I believe the 15 year loan is the worst choice because you are tying up your money making it harder to qualify for loans, and you could be investing that money in something that gives a higher return. If you get a 30 year ARM, the interest rate will actually be lower than the 15 year loan, and you might be able to pay that loan off faster than the 15 year loan.
