Yes, you can borrow for a down payment, but lenders have strict rules about where that money comes from
Most mortgage lenders allow you to use borrowed money for a down payment, but they require you to document the source and prove the loan won't be counted against your debt-to-income ratio. The key restriction: the borrowed money cannot come from another mortgage or home equity line of credit. Personal loans, family loans, and gifts are the routes that actually work. The lender's underwriter will ask for bank statements showing the deposit, a letter from whoever lent you the money, and proof that you can repay both the new mortgage and the borrowed funds.
The reason lenders care is simple: they want to know your actual financial obligation. If you borrow $30,000 for a down payment and then take out a $300,000 mortgage, you owe both. A lender needs to see that your income can cover both debts. If the borrowed money looks like it will become your responsibility to repay, it counts against your debt-to-income ratio and may disqualify you or lower the loan amount you're offered.
Key Takeaways
- Personal loans, family loans, and gifts can fund a down payment, but the lender will verify the source through bank statements and written confirmation from whoever provided the money.
- Money borrowed against your home (home equity loans or lines of credit) cannot be used for a down payment on a new mortgage, and lenders will reject applications that use these sources.
- If you borrow money and are expected to repay it, the monthly payment counts toward your debt-to-income ratio, which may reduce the mortgage amount you may have access to for.
- Gifts from family members do not count as debt, but the lender will require a signed gift letter stating the money is a gift, not a loan you must repay.
- Lenders typically require documentation of the borrowed funds sitting in your bank account for at least two months before closing to prove the money is stable and not borrowed from another lender.
Personal loans: the most straightforward borrowed route
A personal loan from a bank, credit union, or online lender is the cleanest way to borrow for a down payment because the lender can see the full picture upfront. You apply for the personal loan, receive the funds, deposit them into your bank account, and then use them for the down payment. The mortgage lender will see both the personal loan and the mortgage in your credit report and debt calculations.
The catch: a personal loan will lower the amount you can borrow for the mortgage. If you take out a $40,000 personal loan at $800 per month and your income supports a $400,000 mortgage, the personal loan payment reduces the mortgage you may have access to for. The mortgage lender adds that $800 monthly obligation to your existing debts, then calculates how much house you can afford with what's left. This is why some buyers use personal loans only when they're close to their down payment goal and don't want to delay closing.
Personal loans typically charge interest rates between 6% and 36%, depending on your credit score and the lender. The loan term is usually three to seven years. You'll pay interest on the full amount, so a $40,000 loan at 10% over five years costs roughly $9,500 in interest alone.
Family loans: common but require written proof
Borrowing from a parent, sibling, or other family member is common, but the mortgage lender will require a written loan agreement and proof that you intend to repay it. This is where many buyers stumble: they assume a handshake deal is fine, then the mortgage lender rejects the application because there's no documentation.
You need a promissory note — a signed document stating the loan amount, the interest rate (if any), the repayment schedule, and the names of both the lender and borrower. The note must be signed by both parties and ideally notarized. If the family member is charging no interest, the note should say so explicitly. The mortgage lender will ask to see this document before approving your loan.
If the family loan includes a monthly payment, that payment counts as debt on your mortgage application, just like a personal loan would. If the family member agrees to forgive the loan or defer repayment until after you sell the house, the mortgage lender may not count it as debt — but you'll need written proof of that arrangement in the promissory note.
Gifts: no repayment required, but documentation still matters
A gift from a family member or close friend does not count as debt because you have no obligation to repay it. This makes gifts the most favorable option for your debt-to-income ratio. However, the mortgage lender will still require a gift letter — a signed statement from the person giving the money, confirming the amount, stating that it is a gift and not a loan, and confirming they have no expectation of repayment.
The gift letter must come from someone with a reasonable relationship to you: a parent, grandparent, sibling, spouse, or domestic partner. Lenders typically will not accept gifts from unrelated parties or from people who have a financial stake in the transaction (like the real estate agent or seller). The letter should include the giver's name, address, phone number, and relationship to you.
After you receive the gift, the funds must sit in your bank account for at least two months before closing. Lenders call this the seasoning period. The purpose is to prove the money is yours and not borrowed from another lender. You'll need to provide bank statements showing the deposit and the balance for the full two-month period.
Sources that don't work: home equity and retirement accounts
Home equity loans and home equity lines of credit (HELOCs) cannot be used for a down payment on a new mortgage. If you own a home and have built equity, you might think borrowing against that equity is an option — but mortgage lenders explicitly prohibit this. The reason: a HELOC is secured by your current home, and taking out a new mortgage creates a complex lien situation that most lenders won't touch.
Retirement accounts like 401(k)s and IRAs are also off-limits for most conventional mortgages. Some loan programs (like certain FHA loans) allow you to borrow from a 401(k) using a loan feature, but this is rare and comes with tax penalties if you leave your job. The mortgage lender will see the withdrawal on your bank statements and may ask questions about whether it's a loan or a distribution — and distributions trigger tax consequences that reduce your net income on paper.
Credit cards and payday loans should not be used to fund a down payment. These show up on your credit report as high-interest debt and will significantly lower the mortgage amount you may have access to for. A payday loan, in particular, signals financial distress to a mortgage lender and may result in automatic rejection.
How lenders verify borrowed funds and what documents you'll need
When you submit a mortgage application, the lender will order a full credit report and ask for bank statements covering the last two to three months. If they see a large deposit that wasn't there before, they will ask where it came from. You must provide documentation proving the source.
For a personal loan, you'll provide the loan agreement and the lender's statement showing the funds were disbursed to you. For a family loan, you'll provide the promissory note. For a gift, you'll provide the gift letter and the giver's bank statement showing the funds left their account (some lenders request this to confirm the gift is real).
The lender may also ask for a letter of explanation if the deposit timing looks suspicious — for example, if you received a large sum just days before applying for the mortgage. This is standard procedure and not a sign of trouble. Simply explain the source in writing and provide the supporting documents.
Some lenders use automated underwriting systems that flag large deposits automatically. If this happens, respond promptly with the documentation. Delays in providing proof can slow down your closing date.
The impact on your mortgage qualification and interest rate
Borrowed money that you must repay reduces the mortgage amount you may have access to for because the monthly payment counts as debt. The mortgage lender calculates your debt-to-income ratio by adding up all monthly debt payments (car loans, credit cards, student loans, personal loans, and the new mortgage) and dividing by your gross monthly income. Most lenders want this ratio to be 43% or lower, though some allow up to 50%.
If you have a $40,000 personal loan at $800 per month and your gross monthly income is $6,000, that $800 payment uses up 13% of your debt-to-income capacity. This leaves only 30% to 37% for the mortgage payment itself, which means you may have access to for a smaller loan.
Borrowed funds do not typically affect your interest rate directly. The rate depends on your credit score, the loan type, the loan term, and current market conditions. However, if the borrowed money causes your debt-to-income ratio to spike, you may be offered a higher rate as compensation for the increased risk — or you may not may have access to for the loan at all.
Gifts, by contrast, do not count as debt and do not reduce your qualification amount. This is why many buyers prefer gifts when possible.
Frequently Asked Questions
Can I borrow from my 401(k) for a down payment?
Some 401(k) plans allow loans, but most mortgage lenders will count the repayment as debt on your application. If you withdraw from a 401(k) instead of borrowing, you'll owe income tax and a 10% penalty if you're under 59½, which reduces the net amount you receive. Check with your plan administrator and mortgage lender before pursuing this route.
What if my family member gifts me money but I plan to repay them later?
If you intend to repay the money, it must be documented as a loan with a promissory note, not a gift letter. Using a gift letter when you actually plan to repay creates fraud. The monthly payment will count as debt on your mortgage application.
Do I have to tell my mortgage lender about borrowed money for the down payment?
Yes. The lender will see deposits in your bank statements during the underwriting process and will ask about large sums. Failing to disclose borrowed money or misrepresenting its source can result in loan denial or, in extreme cases, legal consequences.
How long does the money need to sit in my bank account before I can use it?
Most lenders require a two-month seasoning period for gifts and borrowed funds. The money must appear in your bank statements for at least 60 days before closing. Some lenders have shorter or longer requirements depending on the loan program.
Will borrowing for a down payment hurt my credit score?
Yes, temporarily. A new loan application triggers a hard inquiry and adds a new account to your credit report, both of which lower your score by a few points. The score typically recovers within a few months as you make on-time payments. However, the lower score at the time of your mortgage application may result in a higher interest rate.
