Of course the total payments on the 30 year term will be more than the 25.
Making such a comparison can lead to a foolish choice. Let me offer an example.

First, this scenario is not a likely one, at least it doesn't represent two offers from the same bank. But let's assume it was 2 offers from different banks. The first bank only give out 25 year loans, and the second, only 30. Of course, you look and see the payment for the 30 is a bit lower, as is the rate. But, the total payments are 16,000 higher. If you use 'total cost' as a criteria, you've made a bad decision. By taking the lower rate, 30 yr loan, and making the same payment as the 25 year loan, i.e. 2639, you would pay it off in 23 years, and actually save 63,000. The mistake is the 'total payments' ignores the time value of money.

That said, I would choose the 30 year term without hesitation if the rates were identical. The first year or two in a house brings unexpected expenses, and it's better to keep that flexibility. Better to stretch out a home loan, literally the lowest rate loan one will ever have, and avoid the higher rate loans that come with credit card or store purchases. (In the US) a mortgage can be prepaid, so if the day after you get the loan you decide that 25 was really the right choice, you simply make the payment amount for the shorter term, and it will amortize the loan down to that. You can also take your time to decide. Move in, set up your home, and increase the payments after the first year or two. If you get decent raises, spend 1/3, save 1/3, and add 1/3 to the mortgage payment, if you wish. That will reduce the term even further.

A simple decision tree

Here is a simple decision tree that should work in almost all cases.

1. What is most important for me?

• Financial flexibility? --> Take the longest term


• Firm motivation to pay faster than needed? --> Take the shortest term


• Flexibilty as long as it does not really cost money --> Go to 2

2. Which interest rate is higher? (note, this is really about the RATE, not about the amount over the total runtime without extra payments because I will assume dicipline on your side to pay off on your planned schedule)

• The 30 year loan has a higher annual interest % --> Flexibility costs money, there is no free lunch!


• The 25 year loan has a higher annual interest % --> Assuming you pay as planned, you will actually save money by paying the 30 year loan in 25 years. Do check that you are allowed to make sufficient extra payments against the principal without penalties. Key assumption here is that interst is calculated each year based on the actual open principal.

I had a similar dilemma as you before, and based on the terms available to me it was in fact cheapest to get a 30 year loan and pay it off in an accelerated rate.

The only contractual 'drawback' being that the amount I could pay off each year without penalties was slightly lower. But assuming you are allowed to pay off 10% of the principal each year, those constraints only hurt if you end up paying the house off in less than 10 years or so.

Commissions are a red herring in this case. It’s not how much he earns that matters to you - it’s how much you need to pay overall, and whether you value the flexibility of dropping your monthly payment from time to time.

You haven’t provided enough information for us to calculate it, but the question to ask your advisor is what your total payment will be, assuming you pay £1640 per month. Make sure they include all fees, charges, early payment penalties if any, and everything else.

Get this total figure for both the 25 year and 30 year terms. You can then compare them to see which works out better. If the 30 year term is more expensive, consider whether the flexibility is worth the extra. If the 30 year total isn’t more expensive, that’s even better for you.

I opted for this twice, for two, two-year fixed terms, on my old property, at the advice of my mortgage adviser.

The reasoning was sound - if for any reason my income drops, I can reduce my payments to the minimum that is feasible with no penalty and with no negotiation with the mortgage lender required.

I can choose to overpay when I do have enough income, and this overpayment is not subject to interest deductions and is taken out of the principal. This makes its impact felt when the fixed rate ends and the mortgage is up for renewal, as it has reduced the Loan-to-Value figure below what would otherwise have been expected for a thirty year term.

Finally, assuming the adviser is not unscrupulous, they have a legal responsibility not to give one advice that is unsuitable, and so based on your and my experience of being advised to do it, I can assume that this strategy has a certain authoritativeness.

Short answer: yes, I think your adviser is pretty much right; and you're right that the total amount you pay doesn't change if you vary the mortgage term.  However, it can't vary too much, or penalties kick in.

I looked into this when I got a mortgage a couple of years ago.  My mortgage guy didn't push a longer term, but I worked out the detail, and came to the same conclusion you did: if you have a repayment mortgage that you're going to pay it off in N years by paying X/month, then you'll pay exactly the same amount if the term written on the mortgage is a bit longer than N. (I.e. there's no direct penalty.)

So a longer term gives you flexibility to reduce your payments if needed (down to the level at which it takes the full term to pay off), but if you don't, then you don't lose out.

However, there's a corresponding disadvantage: mortgages tend to have penalties for very large overpayments.  (In my case, if I pay off more than an extra 10% of the value in any year, I incur a charge of something like £6,500.)  So increasing the term restricts your ability to pay it off much earlier.

So when choosing a term, you have to balance:

• the likelihood of getting into financial difficulty and needing to reduce the payments and take longer to pay it off, against


• the likelihood of being in a particularly good financial position and wanting to increase payments and pay it off early.

In practice, I think a slightly longer term than you need can be a good idea; but do think through the possibilities, and check it with your adviser.

Finally, you may not need to take an irrevocable decision now.  If you get a fixed-rate mortgage or other deal, then it'll revert to the standard variable rate after 2/3/5 years, which would be a good time to remortgage and get another deal — and (I think) you can then pick a new term anyway.

All else being equal, take the 30 year term. Extra flexibility is always a positive. Beware of all the clauses that everyone else has talked about. Get an offset account if you can (an offset account lets you apply savings against the principle for purposes of interest calculation without paying extra directly into the mortgage - these are known by other names in some other countries).

However, there is one thing that nobody seems to have spoken about so far - the fact that regardless of the length of your term you should refinance your mortgage every five years (or sooner).

Banks are a competitive industry. They offer all sorts of discounts to try and draw in customers. Presumably, in five years time your situation will have changed (hopefully for the better). You will have a better credit rating, a higher income and a smaller mortgage. In spite of this, you will be paying a higher rate on your mortgage then than you could be even if it's lower than now. The only way around this is to refinance every few years.

The other advantage of refinancing is that you can either extract equity from the house or, having paid down some of the principle, you can take out a smaller mortgage. Taking out a smaller mortgage (as a percentage of the loan) generally results in lower interest rates.

The reason I bring this up now is that you need to be aware of any exit fees that you may have to pay if you leave the bank. In some countries these are illegal, but in many they're not and the cost of moving away from the bank should be factored in when doing interest rate and mortgage length calculations.

Just don't mess with the 30-year loan, get what you want.

(This assumes that the rate is the same, if the 25yr rate is lower that is an additional reason to choose the 25 year term)

Do two mortgage loans with exactly the same interest rate and repaid at exactly the same monthly rate result in the same total cost of the loan, regardless of which 'term' was originally agreed with the lender?

Yes, as other answers demonstrated... but, there could be other problems issues that annoy you.

I had a situation (USA not UK) where there was no pre-payment penalty and I was paying a little bit extra. But the company servicing the loan had a policy... if you did not mail your payment coupon filled out to indicate that you wanted the additional amount to go to principal, it would be put into your escrow instead. Because I was paying using an electronic check, they were putting the additional funds into the escrow account.

I had pretty much already decided on a term of 25 years, as this comes out with a nice monthly payment that we can afford.

If you want a 25-year loan... and can afford a 25-year loan... then you should get a 25-year loan.

Take a close look at both estimates, and if your mortgage adviser makes more from the 30-year loan you should find a new mortgage adviser and then get your loan.

It was pointed out in a comment that the UK doesn't have they type of escrow accounts that are typical with almost all home loans in the US. (Thanks for that!) But my answer is unchanged.

My point is: the mortgage owner/servicing agent might make you jump through extra hoops instead of doing what you want them to do (apply the extra amount against the principal).

That extra annoyance will make you wish you had the 25.

OP is capable of spreadsheet-ing out all related expenses, and so shouldn't be worried about needing to make the 30-year payment instead of the 25-year payment.

Any "planner type" person wouldn't ask the question if the reason is, "I might not be able to make the 25-year payment".

The OP is asking to make sure they didn't miss something obvious... and they didn't.
