Co-Buying a Home in KY and IN: Smart Move or Big Risk?

Key takeaways

• Co-buying is getting a serious look. In a September 2026 Neighbors Bank survey, 71% of Americans said they would consider co-buying a home with someone other than a spouse if it made owning more affordable (Neighbors Bank).
• Affordability is the reason. The typical existing home cost 4.7 times the median household income in 2025, compared with 3.2 in the 1990s (Harvard JCHS).
• It can get you in sooner. Pooling down payments and incomes, and splitting the monthly bill, can turn "not yet" into "now."
• How you hold title matters. In both Indiana and Kentucky, unmarried co-owners are generally treated as tenants in common unless the deed clearly says otherwise (Indiana Code 32-17-2-1, KRS 381.120 and KRS 381.130).
• Everyone on the loan owes all of it. Co-borrowers are each responsible for the whole payment, no matter how you split it between you (CFPB).
• Put your deal in writing and talk to an attorney. A co-ownership agreement should cover who pays what, who decides what, and how someone gets out.

Short answer: co-buying is getting more attention because buying alone has gotten harder. Prices and payments are near record highs compared with incomes, and rent makes saving tough. Teaming up with a parent, sibling, partner, or friend can pool your down payment and income and get you into a home sooner. It works when every owner can carry their share, you put the hard questions in writing, and you choose your title on purpose.

You and your sister are both paying rent. Or your parent wants to downsize and you want to stop renting. Or you and your partner aren't married yet but are ready to buy. Pooling money can get you into a home sooner.

It can also tie your finances together for years. This guide covers why co-buying is catching on, when it makes sense, and how it works in Southern Indiana and Greater Louisville: how you hold title, how the loan works, and what to put in writing first.

Why is co-buying on the rise?

Short answer: buying a home alone costs far more, compared with income, than it did a few years ago, so more people are open to sharing the purchase.

We haven't found a reliable national count of co-buyers over time. But the national numbers explain why so many people are open to it.

• Prices have outrun incomes. The median existing single-family home sold for 4.7 times the median household income in 2025. In 2019 it was 4.1, and in the 1990s it averaged 3.2 (Harvard JCHS).
• Monthly payments nearly doubled. The mortgage payment on the median-priced home is $2,420 in the latest Harvard figures, compared with $1,240 at the end of 2020 (Harvard JCHS).
• The income bar went up. A household needed about $120,800 a year to afford the median-priced home at the end of 2025, up from $68,700 five years earlier (Harvard JCHS).
• Rent makes saving hard. Asking rents for professionally managed apartments rose 29% from 2020 to early 2026 (Harvard JCHS). First-time buyers name high rent and student loans as the main costs that hold them back from saving (NAR 2025 Profile of Home Buyers and Sellers).
• First-time buyers are fewer and older. First-time buyers were just 21% of buyers in NAR's latest profile, a record low, and their median age hit a record 40 (NAR 2025 Profile of Home Buyers and Sellers).
• Buyers look different now. Married couples fell to 61% of buyers as single buyers gained ground (NAR 2025 Profile of Home Buyers and Sellers).

Put those together and the appeal is clear. In the Neighbors Bank survey, 71% of Americans said they would consider co-buying with someone other than a spouse if it made owning more affordable. And 94% named at least one cost-related reason as a top draw (Neighbors Bank). The survey covered 1,014 U.S. adults on September 3, 2026. Neighbors Bank is a mortgage lender, and the answers describe what people would consider, not purchases they made.

These are national figures. Prices, rents, and incomes in Louisville and Southern Indiana are different, so ask a local real estate agent and lender to run your own numbers.

Why co-buying can make sense in the current market

Short answer: two or more buyers can bring more to the table than one, which can mean owning sooner instead of renting longer.

• A bigger down payment. Two savings accounts reach a down payment faster than one. Splitting the down payment was a top draw for 37% of people in the Neighbors Bank survey (Neighbors Bank).
• More income on the application. Lenders look at co-borrowers' combined income to decide if you can afford the payments (CFPB).
• A smaller share of the monthly bill. Sharing the monthly mortgage payment was the top draw, at 52% (Neighbors Bank).
• Owning sooner instead of renting longer. Sixty percent of people surveyed said they would rather co-buy and own half of a home now than keep renting until they could afford one on their own (Neighbors Bank). Part of each payment pays down a loan on a home you own a share of, instead of going to a landlord.
• Help from family is already common. Among first-time buyers, 22% got help with the down payment from relatives or friends through a gift or loan (NAR 2025 Profile of Home Buyers and Sellers). Co-buying with a parent is one more way families pitch in.

The risks to weigh first

Short answer: you're tied together on the loan and the deed, so plan for the day someone wants out.

• You each owe the full payment. If your co-buyer can't pay, the lender can look to you for all of it, and a late payment can hurt both of your credit reports (CFPB).
• Leaving isn't simple. Moving out doesn't take your name off the mortgage. Someone has to refinance, buy out the other, or sell.
• Plans change. Marriage, kids, a new job, or a falling-out can change what each person wants.
• The wrong title can surprise your family. In Indiana and Kentucky, what happens to a share after a death depends on how the deed is written (details below).

The fix is planning. Most people surveyed agree: 94% said they would likely put a co-buying agreement in writing (Neighbors Bank). Our agreement checklist covers what to include, and a real estate attorney should help you choose your title and draft the agreement.

Who are people co-buying with?

Short answer: mostly family.

Among the people surveyed, parents were the most common choice at 44%, then siblings at 41% and unmarried romantic partners at 40%. Close friends came in at 30% (Neighbors Bank).

Each pairing raises different questions:

• A parent. Will the parent live in the home? What happens to their share when they pass away? How does this fit their estate plan?
• A sibling. What happens if one of you marries, has kids, or takes a job in another city?
• An unmarried partner. Unmarried couples don't have a divorce court to split the home. You'll still own it together until you change that legally (CFPB).
• A friend. How will you handle guests, chores, and a new partner moving in?

How do co-buyers hold title in Indiana and Kentucky?

Short answer: unless your deed clearly says otherwise, unmarried co-owners in both states generally hold title as tenants in common.

The two most common choices for co-owners who aren't married are tenancy in common and joint tenancy with right of survivorship. The CFPB describes them this way (CFPB):

	Tenancy in common	Joint tenancy with right of survivorship
Ownership shares	Can be unequal, like 70/30	Equal shares
If an owner dies	Their share goes by their will or state inheritance law	Their share passes to the surviving owner or owners
Selling a share	Each owner can sell or transfer their share	Rules depend on state law
Common fit	Friends, siblings, unequal down payments	Couples or family who want the survivor to keep the home

Indiana. A deed to two or more people creates a tenancy in common unless the deed expressly says the owners hold in joint tenancy and to the survivor, or that intent clearly appears from the deed. That rule doesn't apply to married couples (Indiana Code 32-17-2-1).

Kentucky. When a joint tenant dies, their part goes to their heirs or their will by default (KRS 381.120). Survivorship applies only when the deed clearly shows that the owners intended the share of the one who dies to go to the others (KRS 381.130).

So in both states, if you want the survivor to keep the home, the deed has to say so clearly. If you want unequal shares, say that too. The title company or closing attorney prepares the deed, but an attorney should help you choose what goes in it.

How does the mortgage work with two or more buyers?

Short answer: the lender looks at all of you together, and each borrower is on the hook for the full payment.

Lenders can't treat you differently because you're not married. The CFPB explains a few other basics (CFPB):

• Combined income counts. Together you need enough income to make the payments.
• The lowest credit score often matters most. Lenders typically use the credit scores of the borrower with the lowest scores. If someone applies without the other, the lender usually won't count the other person's income.
• Each borrower owes the full amount. If you agree to split the payment 50/50 and one person comes up short, the other has to cover it. A late payment can hurt both borrowers' credit.
• Moving out doesn't end the loan. If one owner signs their share over, both stay responsible for the mortgage until it's refinanced or paid off.

Loan programs have their own rules for co-borrowers and for co-borrowers who won't live in the home. Ask a lender to walk all of you through your options before you shop.

What should a co-ownership agreement cover?

Short answer: money in, money out, decisions, and the exit plan.

Most people surveyed want this in writing. In the Neighbors Bank survey, 94% said they would likely put a co-buying agreement in writing, and a buyout or exit plan was the top term they'd include at 60% (Neighbors Bank). The CFPB suggests getting a lawyer to draft a contract that spells out each person's responsibilities and what happens if someone doesn't follow through (CFPB).

A solid agreement usually covers:

1. Contributions. Who put in how much for the down payment and closing costs.
2. Monthly costs. How you split the mortgage, taxes, insurance, utilities, and HOA dues.
3. Repairs and upgrades. Who pays for a new roof, and whether improvements change anyone's share.
4. Missed payments. What happens if someone can't pay their part.
5. Exit plan. How a buyout is priced, how long the others have to buy, and when the home gets sold.
6. Death or disability. How this fits with your title choice, wills, and insurance.
7. Disputes. Agree to try mediation before anyone goes to court.
8. Living rules. Guests, new partners, pets, and who gets which room.

A real estate attorney licensed in the state where the home is located should draft or review it. Property rules generally follow the state where the home sits. A home in Jeffersonville falls under Indiana law even if one co-buyer lives in Louisville. Your attorney can confirm how that applies to you.

Questions to answer before you shop

Short answer: if you can't agree on these now, you won't agree on them later.

• How much can each of us put down, and how much can each of us pay every month?
• How long does each of us plan to live here?
• Who decides on repairs, and up to what dollar amount?
• What happens if one of us gets married, moves, or loses a job?
• If one of us wants out, how do we set the price?
• Do we want the survivor to keep the home, or should each share go to our own heirs?

Write your answers down. The CFPB suggests this so everyone remembers the agreement the same way (CFPB).

Find an agent who has worked with co-buyers

Short answer: look for a real estate agent who asks about everyone's budget and goals, not only the person who called first.

Co-buyers need an agent who keeps every buyer in the loop, shares updates with all of you, and knows when to send you to a lender or attorney. Ask agents you interview whether they've worked with co-buyers before and how they handle disagreements during the search.

FAQs

Why are more people co-buying homes?

Buying alone has gotten harder. Home prices and monthly payments are near record highs compared with incomes, and high rent makes saving tough. Pooling a down payment and income with a parent, sibling, partner, or friend can make owning possible sooner.

Can two unmarried people buy a house together in Indiana or Kentucky?

Yes. Lenders can't treat you differently because of marital status. You'll apply as co-borrowers, and you'll choose how to hold title on the deed.

What's the difference between tenancy in common and joint tenancy?

With tenancy in common, shares can be unequal and each owner's share passes by their will or state law when they die. With joint tenancy with right of survivorship, the surviving owner or owners keep the deceased owner's share.

What happens if I don't say how we hold title?

In both Indiana and Kentucky, co-owners who aren't married are generally treated as tenants in common unless the deed clearly provides for survivorship. Ask an attorney to confirm the wording.

If my co-buyer stops paying, am I responsible?

Yes. Each co-borrower is responsible for the full mortgage payment, no matter how you split it privately. A missed payment can hurt both of your credit reports.

Do we need a lawyer to co-buy a home?

It's strongly recommended. An attorney can help you choose how to hold title and draft a co-ownership agreement that covers payments, repairs, and an exit plan.
