Mortgage Note Investing: The Complete Guide for 2026

Mortgage note investing is buying the debt secured by a house instead of the house itself: you buy the promissory note and the mortgage or deed of trust that secures it, and the borrower's payments come to you. The market it draws from is large: one-to-four-family residential mortgage debt outstanding was $14.98 trillion at the end of the second quarter of 2026, per table F4.5a.s of the Federal Reserve's Z.1 Financial Accounts release of September 11, 2026. Investors buy single loans or small pools out of that market, at prices driven by the loan's payment status, its lien position and the value of the house behind it.

You are not the landlord. There are no tenants and no repair calls; you own paper, and the job is to buy it at a price that still works if the borrower never pays. If the vocabulary is new, what mortgage note investing is covers the players and terms; this guide is the full process.

What is a mortgage note?

Every home loan starts with two documents. The promissory note is the borrower's written promise to repay. It sets the principal, the interest rate, the payment schedule and the maturity date, and it says what happens on default. The mortgage (or deed of trust in many states) attaches a lien to the property. The note says "you owe me money." The mortgage says "and this house backs that promise."

When a loan is sold, two more documents move ownership:

• The assignment of mortgage transfers the lien from seller to buyer and is recorded in the county land records.
• The allonge endorses the promissory note to the new holder and travels with the original note in the collateral file.

Those four documents make a loan tradeable. When it's sold, the borrower's obligation doesn't change; only the identity of who they owe does.

Banks sell loans to free up capital, manage risk, or exit loan types they no longer want to hold. Delinquency forces the question. Under the FFIEC's Uniform Retail Credit Classification and Account Management Policy, a bank should get a current assessment of the property's value no later than 180 days past due on a loan secured by residential real estate, and charge off any balance above that value less cost to sell. A charge-off is an accounting entry, not forgiveness: the debt is still owed and the lien still exists, but the bank now has a reason to move the asset off its books.

Performing vs. non-performing notes

The secondary market sorts loans by payment status. Banks report a loan as noncurrent when it is 90 days or more past due or on nonaccrual status, and at June 30, 2026, 1.40% of FDIC-insured institutions' 1–4 family residential mortgages (excluding home equity loans) were noncurrent, per Table V-A of the FDIC's Quarterly Banking Profile for the second quarter of 2026.

A performing loan is the most passive version of this business, a re-performing loan sits in the middle, and a non-performing loan carries the deepest discounts because the outcome is uncertain and someone has to work it. The trade-offs are laid out in performing vs. non-performing notes, and the beginner's roadmap explains why many new investors start with non-performing second liens.

How do note investors make money?

There are three ways the money comes back, and none of them is guaranteed.

Payments on a discounted balance. Buy a performing note for less than its unpaid principal balance and the same payments produce a higher yield on what you paid. Take a hypothetical loan with a 6% note rate, a $500 monthly payment and 240 payments left. Its balance is about $69,790. A buyer who requires an 8% yield on those payments would pay about $59,777; a buyer who requires 10% would pay about $51,812. That is standard present-value math, before servicing costs and before any chance of default; you can run your own loans through the TVM calculator.

A resolution on a non-performing note. You buy the defaulted loan at a discount and work toward an outcome: the borrower reinstates, you agree a loan modification or a discounted payoff, the borrower sells in a short sale or hands back the house through a deed in lieu, or you foreclose. What you make depends on the price you paid against the outcome, less legal costs and the time it took.

A sale of the note. A loan you bought non-performing and got paying again can be sold to a buyer of performing paper, who prices it on yield rather than on recovery.

Where to buy mortgage notes

The secondary mortgage market has no central exchange. Deal flow comes through relationships and a handful of channels:

• Online marketplaces. The easiest place to start: you can browse loan data and, once you qualify as a buyer, bid without a prior relationship. To see what's listed right now, browse mortgage notes for sale. The trade-off is competition on the best loans.
• Brokers. Brokers source loans from banks, funds and other holders and send tapes (spreadsheets of loan data) to their buyer lists. The way to stay on those lists is to close what you bid on.
• Servicer trade desks. Some loan servicing companies connect their clients' sellers with buyers. The payment histories tend to be cleaner because the loans are already boarded.
• Direct outreach. Owner-finance sellers, private lenders and small funds hold notes that never reach a marketplace. Finding them takes public-records research and patience.
• Conferences and peers. As you scale, direct relationships with institutional holders become the best source.

Each channel is covered in more depth in how to find and buy mortgage notes for sale.

Can you buy non-performing notes directly from banks?

Usually not as an individual. In our experience banks sell distressed residential loans mostly in pools, to buyers they have already vetted, and individual investors buy those loans one step later, from the funds, brokers and marketplaces that split the pools. Why you can't buy mortgage notes directly from banks explains the mechanics, and who sells non-performing notes maps the sellers. If you want to know which banks are carrying distressed loans, the NPL Explorer ranks banks and credit unions on noncurrent loans and foreclosed property from their call reports, and our Q2 2026 NPL report summarizes the trends.

How to buy a mortgage note in five steps

1. Screen the tape

The seller sends a tape. You run every loan through a waterfall that checks lien position, geography, property value, delinquency and bankruptcy status in a set order, so you drop the non-starters before you spend money on reports. The pre-bid waterfall process walks through it.

2. Submit a letter of intent

Your letter of intent (LOI) states your price, a due diligence contingency, a timeline and your proof of funds. It is usually non-binding, but treat it as a commitment. Ask for exclusivity so the seller doesn't shop the loan while you work, and make the due diligence window long enough for your reports to come back.

3. Complete due diligence

Due diligence is your main defense against buying a problem. It covers five areas, and the due diligence checklist has the full list.

Property value. What is the collateral worth? A BPO (broker price opinion) from a local agent is the usual first read, and in our experience it costs well under a full appraisal. For a sense of appraisal pricing, the VA's fee schedule effective May 1, 2026 sets single-family fees from $650 to $1,100 at the state level, with some counties higher (VA Appraisal Fees and Timeliness).

Title. Is the title what the seller says it is? An ownership and encumbrance report shows the current owner, the open mortgages, liens, judgments and tax status. One vendor, ProTitle USA, lists an average of roughly $90 per O&E report, varying by location. How to read one is in the O&E report guide. I have seen investors skip the title report to save its cost and later discover a tax lien that cost them many times more.

Borrower. What is the borrower's situation? Pulling a credit report needs a permissible purpose, and the Fair Credit Reporting Act allows one for a potential investor or servicer assessing the credit or prepayment risk of an existing credit obligation (15 U.S.C. §1681b(a)(3)(E)). Occupancy (owner-occupied, rented or vacant) shapes your workout options. A bankruptcy filing triggers an automatic stay that halts most collection and lien enforcement against the debtor and the debtor's property (11 U.S.C. §362(a)); borrower bankruptcy for note investors covers what that means for your plan.

Collateral file. Are the documents complete? The original note, the mortgage or deed of trust, the full assignment chain and every allonge must be present and properly executed. How to audit the collateral file is the checklist, and what happens if the promissory note is missing covers the most serious gap.

Legal. Does the statute of limitations still allow enforcement? Does the state require mediation or a longer cure period? Is the borrower a servicemember protected by the Servicemembers Civil Relief Act? Check each loan by loan.

If the reports confirm the seller's data, you proceed. If they don't, you renegotiate or walk.

4. Sign the loan purchase sale agreement

The loan purchase sale agreement (LPSA) is the binding contract. Read the representations and warranties closely: they decide your recourse if the seller's data turns out to be wrong, and a repurchase clause is the most important protection in the document. The loan purchase sale agreement guide covers what to negotiate.

5. Fund, record and board

Wire the purchase price. On a first trade with an unfamiliar seller, use a third-party escrow agent. Send your servicing and collateral delivery instructions with the wire so the seller can start the transfer.

Record the executed assignment as soon as you have it. Recording puts your ownership in the public record, where anyone dealing with the property looks for the lienholder; how to record the assignment of mortgage explains the mechanics. The original collateral file often arrives after you've funded; when it does, audit it against the images you reviewed before closing.

How to price a note

Pricing follows the loan type. How to price performing and non-performing notes goes deeper; here is the logic.

Performing and re-performing loans are priced to a yield, as in the hypothetical above, with a further discount on re-performing loans for the chance the borrower defaults again.

Non-performing loans are priced to the expected recovery. You are buying an uncertain outcome, so you estimate what each exit would produce (modification, discounted payoff, deed in lieu, foreclosure), net of legal costs and holding time, weight each by its probability, and discount the result for time. First liens tend to be priced off the property's fair market value, because your recovery comes through the house; junior liens off the balance, because the equity behind the senior lien is uncertain. How to value NPLs to make an offer shows the method.

Time is the input most new investors underestimate. ATTOM's midyear 2026 foreclosure report puts the average time in the foreclosure process at 563 days for homes foreclosed in the second quarter of 2026, ranging from 155 days in Texas to 3,491 days in Louisiana. State law drives much of that spread; judicial vs. non-judicial foreclosure covers how it should move your bid.

After you buy: servicing and resolution

Servicing transfer

Your licensed servicer boards the loan. On the residential mortgage loans RESPA covers (home equity lines of credit are excluded), Regulation X requires the old servicer to send the borrower a notice of transfer at least 15 days before the transfer takes effect and the new servicer to send one within 15 days after, or both to send a single notice at least 15 days before (12 CFR 1024.33(b)). Separately, on a consumer mortgage loan, if you acquire more than one mortgage loan in any 12-month period, Regulation Z requires you, as the new owner, to mail or deliver a transfer notice to the borrower on or before the 30th calendar day after the transfer (12 CFR 1026.39). Confirm whether your servicer sends it for you. Sign your servicing contract before you close your first deal, not after.

Managing the loan

For performing loans, the work is monitoring: payments through your servicer, property taxes and insurance kept current, and a fast response if the borrower falls behind. For non-performing loans, the work starts at boarding, when you, your servicer and your attorney pursue one of the resolutions above. A consensual one is almost always better: a borrower who re-performs produces cash flow, while a foreclosure costs time, legal fees and carrying costs. I treat foreclosure as the last option, not the first.

How much money do you need to start?

It depends on the loan type and lien position you buy; how much money you need to start investing in mortgage notes breaks it down by budget. Whatever the price, budget for four buckets:

• The purchase price of the loan
• Due diligence: valuation, title or O&E, and a credit report where you have a permissible purpose
• Reserves: recording fees, back property taxes, force-placed insurance and legal costs if the loan needs a workout or foreclosure
• Servicing: ask for the servicer's full fee schedule, including boarding and default-servicing fees, before you sign

Undercapitalized investors get hurt when timelines stretch. You also need infrastructure before you bid:

If you want exposure with less capital or less work, the options are mortgage note funds, co-investing alongside an experienced operator, and partial interests in a loan's payments. Retirement money can also buy notes; how to buy mortgage notes with a self-directed IRA covers the custodian and prohibited-transaction rules.

What are the risks of mortgage note investing?

The downsides of mortgage note investing covers the business-level drawbacks too: reinvestment risk, sourcing, leverage limits and licensing.

Before you bid on your first note

Answer these five questions. If any answer is no, don't bid yet.

1. Is a licensed servicer under contract? Not shortlisted: signed, with its fee schedule in hand.
2. Does the price still work if the borrower never pays? Run the foreclosure scenario at your state's timeline, with legal costs and back taxes.
3. Are the reports back? Value, title or O&E, and the collateral file images, all matching the tape.
4. Does the LPSA give you a repurchase remedy? If the seller won't stand behind its data, price that in or walk.
5. Can you record the assignment and audit the file the day they arrive? If not, you're not ready to close.
