Can Your TSP Be Used to Buy Real Estate? What Federal Employees Should Know
Federal Pension Advisors, a retirement planning firm specializing in federal employee benefits, publishes this guide to help federal employees understand TSP borrowing rules before they apply.
Yes, but only in a narrow way.
Your TSP, or Thrift Savings Plan, is the federal government's tax-advantaged retirement savings program for civilian employees and uniformed service members. You can use it, through a residential loan, to help finance the purchase or construction of your primary residence. However, it's also important to understand potential TSP risks after early retirement, including withdrawal timing, taxes, and how long your savings may need to last.
You cannot use TSP funds to buy rental property, a vacation home, land alone, or any other investment real estate. TSP participants cannot directly purchase and hold real estate in their TSP account, unlike some self-directed IRAs.
That distinction matters. Many federal employees hear "TSP loan" and assume it works like an account that can hold rental property. Understanding how TSP investments perform can also help put the loan decision in context; see our latest TSP performance in August 2026 analysis.
It doesn't. This guide covers what the TSP residential loan can and can't do, what it costs you in lost account growth, and the alternatives worth weighing before you borrow against your own retirement.
What a TSP Residential Loan Actually Covers
The TSP residential loan is the specific loan option designed to help finance the purchase or construction of a primary residence. It's one of two loan types available to TSP participants.
You can take a general-purpose loan for any reason, with a repayment term of 12 to 60 months. A residential loan only covers a primary residence purchase or construction, with a repayment term of 61 to 180 months.
Under 5 CFR 1655.2, you can apply for either loan type if you're in pay status, eligible to contribute to the TSP, and have at least $1,000 in employee contributions and earnings in your account. More than 30 business days must have passed since you last repaid a TSP loan in full.
Your interest rate isn't set by a bank. Under 5 CFR 1655.7, it's the monthly G Fund rate in effect on the 15th of the month before you submit your loan request, and it stays fixed for the life of the loan.
That rate changes month to month. For more information on TSP investment options and the TSP Mutual Fund Window, see our detailed guide before you apply. Check TSP.gov for the current figure.
What a Residential Loan Cannot Be Used For
The restrictions catch people off guard. Under 5 CFR 1655.20, a residential loan will not be made to pay off an existing mortgage or otherwise finance a home you already own.
Your primary residence cannot be a second home or vacation home, and you can't have more than one primary residence at a time. Building an addition, renovating an existing home, or purchasing land only does not qualify as purchasing a primary residence.
If you're receiving FERS disability retirement and considering additional income or employment, review the FERS disability retirement 80% earnings limit before making financial decisions.
The amount you request also can't include points, loan origination fees, or real estate taxes.
In plain terms, the TSP residential loan helps you get into a home you'll live in. It's not for renovating a home you already own, financing a second property, or restructuring debt you already have.
Can You Use Your TSP to Buy an Investment Property?
No. This is the point most federal employees get wrong.
TSP participants cannot directly purchase and hold real estate in their TSP account, and residential loans are restricted to a primary residence you or your spouse will occupy. There's no loan or investment feature that lets you purchase rental or other investment real estate through the plan, whether through a loan or a withdrawal.
This is a meaningful difference from some private-sector retirement accounts. Certain self-directed IRAs allow real estate investment inside the account itself. The TSP was not designed that way.
The Real Cost of Borrowing Against Your TSP
A TSP loan isn't free money, even though you're technically repaying yourself. Under 5 CFR 1655.9, the amount you borrow is removed from your account when the loan is disbursed, and it stops generating earnings while it's outstanding. Before taking a TSP loan, federal employees should also review their broader retirement plan, including their TSP strategy, retirement timing, and other benefits.
If your TSP funds would have earned more than your fixed loan rate over that period, you don't get that growth back.
There's also a separation risk, though it isn't automatic. If you leave federal service with an outstanding loan and don't begin repayment or pay it off within the deadline your TSP recordkeeper sets, the balance is declared a loan offset and reported to the IRS as taxable income for that year.
You may be able to roll a loan offset amount into an IRA to avoid taxes and penalties on it, under the rollover rules that apply to plan loan offsets. Talk to a tax professional about your specific deadline and situation before you borrow, not after you separate.
In-Service Withdrawals: Not a Real Estate Workaround
Some federal employees ask whether an in-service withdrawal, rather than a loan, could fund a real estate purchase. In-service withdrawals have their own eligibility rules, generally tied to age 59½ or a financial hardship, and neither category is built as a real estate purchase mechanism. Understanding how changes in your federal position can affect your broader retirement timeline is also important, particularly with Schedule Policy/Career.
An in-service withdrawal can carry different tax consequences than a TSP loan, including possible taxes and penalties depending on your age and the type of withdrawal. Withdrawn funds also don't get repaid into your account the way a loan does.
Compare the potential taxes, penalties, lost retirement savings, and repayment requirements of each option before you choose between them, and confirm current eligibility rules directly with TSP.gov.
Steps to Apply for a TSP Residential Loan
- Confirm eligibility and identify a qualifying property. Your primary residence can be a house, townhouse, condominium, co-op share, or mobile home that you or your spouse will occupy. It cannot be a second home.
- Gather your purchase documentation. You'll need a signed sale or purchase contract, or, for new construction, a signed builder's agreement.
- Calculate your maximum eligible amount. Under 5 CFR 1655.6, it's the smallest of your own contributions and earnings, 50% of your vested balance (or $10,000, whichever is greater) minus any outstanding loan balance, or $50,000 minus your highest outstanding loan balance in the past 12 months.
- Submit your loan request in the form and manner the TSP recordkeeper requires. Check TSP.gov or contact the ThriftLine for the current application process and required documentation.
- Review the interest rate and repayment term before accepting. Your rate locks at the G Fund rate for the 15th of the prior month and stays fixed for up to 180 months.
- Repay through payroll deduction. For active federal employees, loan payments are made through payroll deduction under the terms of your loan agreement, and your agency cannot stop the deductions at your request.
TSP Contribution Limits for 2026
Whether or not you borrow against your TSP for a home purchase, know what you're borrowing against.
According to IRS Notice 2025-67, the 2026 elective deferral limit for TSP contributions is $24,500. Workers turning 50 or older during the year can add an $8,000 catch-up contribution, and those turning 60 through 63 qualify for an $11,250 "super" catch-up under the SECURE 2.0 Act. Federal employees can also learn more about TSP contribution strategies through free TSP webinars.
Money you borrow against the account stops generating TSP earnings while the loan is outstanding. That's why a residential loan should be a deliberate decision, not a default one.
What to Weigh Before You Borrow
The TSP residential loan can help you buy a home you'll live in, subject to a $50,000 maximum, a fixed rate, and up to 180 months to repay. It cannot fund an investment property, a second home, land alone, or renovations to a home you already own.
Before borrowing, weigh the lost account growth on the funds you pull out against the benefit of a lower down payment or avoided mortgage insurance. Consider using a federal retirement estimate to understand how the loan could affect your overall retirement picture. Understand the loan offset rules too, in case you separate before the loan is repaid.
Federal employees considering a TSP loan may want to review the decision alongside their broader retirement income plan. Schedule a free retirement consultation. Federal Pension Advisors, a retirement planning firm specializing in federal employee benefits, does not provide this article as individualized financial or tax advice. Consult a qualified advisor about your specific situation.
Frequently Asked Questions
Can I use my TSP to buy a rental property?
No. You can't use TSP funds to purchase investment or rental real estate. The residential loan program is restricted to your primary residence, and TSP participants cannot directly purchase and hold real estate inside the account.
How much can I borrow from my TSP to buy a house?
Your limit is the smallest of three figures: your own contributions plus earnings, 50% of your vested balance (or $10,000, whichever is greater) minus any outstanding loan, or $50,000 minus your highest loan balance from the past 12 months. The minimum loan amount is $1,000.
What happens to my TSP loan if I leave my federal job?
If you don't begin repayment or pay off the balance by the deadline your TSP recordkeeper sets, the remaining amount is declared a loan offset and reported to the IRS as taxable income. You may be able to roll that offset into an IRA to avoid taxes and penalties on it.
Can I use a TSP loan to refinance my current mortgage?
No. A TSP residential loan won't be made to pay off an existing mortgage, and it can't fund a renovation, an addition, or a land-only purchase.
Is the interest on a TSP loan tax-deductible like a mortgage?
Generally, no. TSP loan interest isn't deductible the way mortgage interest can be. You're repaying yourself with interest that goes back into your own account, but talk to a tax professional about how it applies to your specific return.
What's the difference between a TSP general purpose loan and a residential loan?
A general purpose loan can be used for any reason and repaid over 12 to 60 months. A residential loan only funds a primary residence purchase or construction, with 61 to 180 months to repay and a $100 fee instead of $50.
