Buying a home together: who needs coverage on a joint mortgage

Two people sign a mortgage on the same day, and the lender asks both of them for the same promise: repay the whole loan. That detail is the center of the insurance question. If one co-borrower dies, the debt does not shrink by half. The survivor is generally still responsible for the payments, along with taxes, insurance and repairs, on the income that remains. So the real question is not "who needs coverage" in the abstract, but "what could the survivor afford, and for how long?"

This post gives you criteria to answer that for your own household, a worked example with a mortgage balance, and a decision list that ends in a clear choice among four common outcomes: one policy, two policies, a small policy or none for now. The couples and numbers are hypothetical, with round figures used only to show the arithmetic.

What a joint mortgage does and does not do

A few mechanics are worth knowing before you compare options.

Both borrowers are usually liable for the entire loan. A lender looks to each signer for the full balance, not half of it. If one signer dies, the loan stays in place, and the survivor continues paying. Federal law generally limits a lender's ability to demand full repayment just because a co-owner died, but the monthly payments still have to be made. Ask your lender or servicer how it treats a death, and ask a real estate or estate attorney what applies in your state.

Title and the loan are separate. The mortgage is a debt. The deed is how you own the home. You can have two names on the loan and different ownership on the deed, or the reverse. How title is held decides what happens to the owner's share at death:

• Joint tenancy with right of survivorship usually passes the deceased owner's share to the surviving owner automatically.
• Tenancy in common lets each owner leave their share to someone else through a will. If one partner dies, the share may go to a parent, sibling or child instead of the survivor.
• Community property states have their own rules for spouses. See community property states and life insurance for how they interact with insurance.

An unmarried couple has fewer automatic protections than a married one. The post what spouses get automatically that unmarried partners must build covers that ground, and the guide life insurance for unmarried partners explains how insurers treat partners. In general, two people who share a mortgage have a financial interest in each other that supports buying coverage on each other, which is the idea behind insurable interest: who can buy life insurance on whom.

Life insurance is a separate contract. No policy is attached to a mortgage unless you buy one that is. A lender does not require life insurance on most home loans, and nothing in the loan pays it off at a death.

The criteria

Use five questions. Answer them for each partner.

1. Could the survivor afford the payment on one income? This is the main test. Compare the full housing payment, including taxes and homeowners insurance, with the survivor's income.
2. Who depends on each income? Children, a parent or a partner who is not on the loan add weight to the answer.
3. What other money stands behind the household? Savings, retirement accounts, employer group life and a separate emergency fund all reduce what insurance has to do.
4. How is the home owned? Joint tenancy, tenancy in common and sole ownership lead to different results at death.
5. How long will the need last? A 30-year mortgage with 28 years left is a longer exposure than one with 6 years left.

A worked example

Say Alex and Jordan buy a home with a $320,000 mortgage. The monthly payment, including taxes and homeowners insurance, is a hypothetical $2,600. Alex takes home about $5,400 a month. Jordan takes home about $3,700 a month. They have no children and $40,000 in savings. Each has group life at work equal to one times salary.

First, the share of take-home pay that housing takes:

• Together: $2,600 ÷ ($5,400 + $3,700) = $2,600 ÷ $9,100 = about 29%
• If Alex dies and Jordan carries the payment alone: $2,600 ÷ $3,700 = about 70%
• If Jordan dies and Alex carries it alone: $2,600 ÷ $5,400 = about 48%

A common rule of thumb says housing costs above roughly 30 to 35 percent of take-home pay strain a budget. It is a rule of thumb, not a legal or actuarial standard. By that measure, the household is comfortable together, Alex survives with a heavy burden, and Jordan would face a payment that takes most of a paycheck.

Both partners need to consider coverage, but the amounts differ. Here is one way to frame it.

If Alex dies. Jordan would carry 70 percent of take-home pay in housing. Jordan could (a) sell the house, (b) refinance if eligible, (c) pay down the loan with a death benefit or (d) cover the gap for several years while adjusting. Say they want the death benefit to pay off the mortgage plus keep a year of costs in reserve: $320,000 + $31,200 (that is $2,600 × 12) = $351,200. Rounded, a $350,000 policy on Alex.

If Jordan dies. Alex would carry 48 percent of take-home pay. That is heavy but possibly workable with some cuts. Coverage to pay off the mortgage is one choice. A smaller amount that bridges five years of the housing gap is another. The gap is the housing payment minus the share Alex could comfortably carry: if Alex is comfortable at 30 percent, that is 30% × $5,400 = $1,620, so the gap is $2,600 − $1,620 = $980 a month, or $980 × 12 × 5 = $58,800 over five years. A policy of $100,000 would exceed that and leave room for other costs.

So Alex and Jordan might choose a larger policy on Alex and a smaller one on Jordan. The numbers are invented to show the method. The How much life insurance do I need? lets you try your own.

Now compare options for the loan itself. A level term policy matched to the mortgage, such as 30 years, pays the same amount whenever the death occurs. A decreasing term policy has a death benefit that falls over time, roughly following the loan balance, and is typically cheaper than a level policy of the same starting amount. The glossary entries for decreasing term insurance and level term insurance explain both, and the guide mortgage protection insurance vs term life compares products sold specifically as mortgage protection with ordinary term life. The key trade-off is that level term keeps its full value as the loan shrinks, which helps with other costs, while decreasing term can fit a single purpose more cheaply. Make sure any decreasing-term policy pays to your beneficiary and not the lender unless you intend that.

One income or two?

The split of income often decides the answer more than the size of the loan.

Two similar incomes. Each partner's income supports the housing payment. If either dies, the survivor loses roughly half the household income. Both need coverage, at amounts that bring the survivor's finances to a sustainable level. The post two incomes, one mortgage: which partner should carry more coverage explores how to split the amounts when the incomes are not equal.

One income and one partner at home or part time. The earner needs the larger policy, because the survivor would lose most of the income. The other partner still matters if they do unpaid work the household would have to buy, such as child care. Without children, the need may be smaller. With children, a policy on the lower earner is often a sound inclusion.

One partner on the loan, both on the deed, or the reverse. If only one person is on the loan, that person's death changes the lender's position, and the survivor may need to qualify or assume the loan. Ask the lender before you close. This is a legal and lending question, not an insurance one.

When coverage matters less

Sometimes the right answer is a small policy or none yet. Three situations:

• A small mortgage relative to income and savings. If the survivor could pay it off from savings or manage it on one income, the insurance does little.
• A short remaining term. If the mortgage will be paid in a few years, the exposure is brief.
• A budget that would be stretched. A policy bought and dropped in year two protects no one. A smaller policy kept in force beats a large one that lapses.

Employer group life adds a layer. It is often one or two times salary at no cost and ends when the job ends, so treat it as a base that may disappear, and not as a plan.

Offers you may see at closing

Around the time of a home purchase, offers for mortgage-related insurance often arrive in the mail or from the lender. The product usually called mortgage protection or mortgage life insurance pays a benefit tied to the loan, often decreasing as the balance falls, and in some versions it pays the lender directly. The glossary entry mortgage life insurance describes the product, and the guide mortgage protection insurance vs term life explains how it differs from ordinary term life.

Three questions sort these offers quickly:

1. Who is the beneficiary? If it is the lender, the money pays off the loan and your survivor decides nothing. If it is your partner, the survivor chooses how to use it.
2. Does the benefit fall as the loan falls, and does the premium? A shrinking benefit with a flat premium costs more over time per dollar of protection.
3. How was the price set, and what does it exclude? Some offers use simplified underwriting with narrower questions, which can mean higher prices for healthy buyers and easier access for others. Compare the price per $1,000 of coverage with a term quote for the same amount.

Nothing here says such a product is wrong for you. It says to compare it with the alternative on the same terms, which is the neutral way to treat any contested product.

A second example: one earner, one partner at home

To see the criteria applied to a different household, say Sam and Lee buy a home with a $400,000 mortgage and a hypothetical $3,000 monthly housing payment. Sam takes home $7,000 a month. Lee works part time and takes home $1,200 and handles most of the care of their young child.

If Sam dies, the household's income falls from $8,200 to $1,200. The housing payment alone would be $3,000 ÷ $1,200 = 250 percent of Lee's pay, which is impossible without new income, a sale or a large death benefit. Sam's policy therefore has to cover the mortgage, several years of living costs and the child. Say their other living costs are $4,000 a month. If the mortgage were paid off by a death benefit, the housing payment would disappear and Lee's $1,200 would leave a shortfall of $4,000 − $1,200 = $2,800 a month. Replacing that for ten years costs $2,800 × 12 × 10 = $336,000. Adding the $400,000 to clear the mortgage gives $400,000 + $336,000 = $736,000. That is a large policy for a household of this size, and the example shows why the earner in a one-income household carries most of the weight.

If Lee dies, Sam loses $1,200 a month of income and gains the cost of child care. Say child care for a young child would be $1,500 a month for six years: $1,500 × 12 × 6 = $108,000. A policy on Lee of about $100,000 to $150,000 would be a sensible starting point. Lee's coverage is smaller than Sam's, and it is still necessary.

What to ask the lender and the servicer

You do not need the lender's help to buy life insurance, but a few answers will help you plan.

• What happens to the loan if one borrower dies? What documents does the servicer need, and who may speak with it?
• Can the survivor stay on the loan without refinancing? Are there any conditions?
• If only one of you is on the loan, what happens to the other's right to the home?
• Is there an escrow account for taxes and insurance, and how would a death affect it?
• Does the loan have a requirement for life insurance? Most do not.

Write down the date, the name and the answer. Servicers change over the life of a loan, and written notes outlast memory.

The decision list

Answer in order and stop when a row fits.

1. If the survivor could carry the housing payment on one income without strain, and you have no dependents, a small policy or none is reasonable. Review it at each major change.
2. If one survivor would be strained but the other would not, buy a larger policy on the partner whose death would hurt the household more, and a smaller one on the other.
3. If either survivor would be strained, buy a policy on each partner, sized to the gap or to the mortgage balance.
4. If there are children or other dependents, add their costs to the amount for each partner before you choose, and read the sizing guides on life insurance for homeowners and using term life insurance to cover a mortgage.
5. If you are unmarried, also check title, wills and beneficiary forms, because the law provides fewer defaults. Name each other as beneficiary on the policies, and consider whether each of you should be the owner of the policy on the other.
6. If the mortgage term is long, choose a term that matches the years the survivor would need help, using how long a term should you buy: 10, 20 or 30 years.
7. If you are unsure, or your situation includes a business, a trust or a complicated title, talk to a fee-only planner or an estate attorney.

Paperwork to do after you choose

• Decide who owns each policy and who is the beneficiary. A common arrangement is for each partner to own their own policy and name the other as primary beneficiary. See policy owner.
• Name a contingent beneficiary on each policy.
• Check the title to the home and, if you are unmarried, consider a will.
• Keep a record of the mortgage servicer, loan number and policy details in one place where the survivor can find it.
• Review at refinance, a child's birth, a job change or a large paydown.

Key takeaways

• A joint mortgage generally makes each borrower liable for the whole loan, so a death leaves the survivor with the full payment and the question is what they could carry alone.
• Compare the housing payment with each person's take-home pay; the partner whose death would leave the other with the heavier burden usually needs the larger policy.
• Level term keeps its value as the loan shrinks; decreasing term costs less but fits mostly the loan balance.
• Title and marital status change what happens automatically, and unmarried partners should check deeds, wills and beneficiary forms.
• A small policy kept in force is better than a large policy that lapses, so size to what the budget can hold.
