Buying a mortgage note used to require being plugged into the right network of brokers, bankers, and attorneys — all through handshake deals and fax machines. Today, platforms like Paperstac have digitized the entire transaction, giving everyday investors access to a transparent, searchable marketplace where notes are bought and sold with the same ease as an e-commerce order.
This guide walks you through every step — from setting your strategy to collecting your first payment.
How Do I Define My Investment Criteria Before Buying?
The most common mistake new note investors make is browsing listings before knowing what they want. Define your criteria first — it saves time and prevents emotional purchases.
Note Type
Performing or non-performing? First or second lien?
Target Yield
What minimum return do you need? 8%? 12%?
Geography
Which states? Consider foreclosure laws and timelines.
Max LTV
How much equity buffer do you require? 75% LTV max?
UPB Range
Min/max unpaid balance you’ll consider buying.
Hold Strategy
Cash flow? Re-perform and resell? Foreclose and flip?
Pro tip: Write out your buy box before you log in. A focused investor with a clear criteria sheet closes faster and negotiates from a position of strength.
How Do I Find Mortgage Notes for Sale on Paperstac?
Once you have your criteria, Paperstac’s marketplace makes searching straightforward:
| Filter | What It Does | Recommended Setting |
|---|---|---|
| Payment Status | Performing, non-performing, sub-performing | Match to your risk tolerance |
| Lien Position | 1st vs. 2nd lien | Start with 1sts for lower risk |
| State | Filter by borrower property location | Focus on judicial vs. non-judicial states |
| Property Value | Estimated market value of collateral | Ensure sufficient equity over UPB |
| UPB Range | Unpaid principal balance | Set min/max to match your budget |
| Interest Rate | Rate on the original note | Higher rate = higher payment stream |
| LTV | Loan-to-value ratio | Under 75% for conservative investing |
Paperstac’s collateral verification process — conducted during closing by a third-party auditor — confirms that sellers are the legitimate, documented owners of the notes they list, helping eliminate the daisy-chain brokers who used to flood note forums with deals they didn’t own.
How Do I Analyze a Mortgage Note to Know If It’s a Good Deal?
Evaluating a note comes down to one core question: what yield will I earn at this purchase price?
Sample Note Analysis
*This is a simplified illustration. Always use a financial calculator (HP12C or equivalent) to verify yield.
Key Metrics to Evaluate
- Yield — Your actual return at the purchase price (not the note rate)
- LTV — Lower is safer; 70% or under provides meaningful equity buffer
- Payment history — How many consecutive on-time payments has the borrower made?
- Property type — Single-family is most liquid; avoid specialty properties early on
- State foreclosure timeline — Judicial states (NY, FL) can take 2–3 years; non-judicial states (TX, GA) are much faster
- Loan seasoning — Older loans with consistent payment history carry lower risk
What Due Diligence Do I Need to Do Before Buying?
Due diligence is where most beginners underinvest their time — and where experienced investors make their money.
| Due Diligence Item | Purpose | Priority |
|---|---|---|
| Original Note & Mortgage | Confirm the debt exists and terms match the listing | 🔴 Critical |
| Allonge / Assignment Chain | Verify unbroken chain of title | 🔴 Critical |
| O&E Report | Check for liens, judgments, encumbrances | 🔴 Critical |
| BPO | Validate property value to confirm LTV | 🔴 Critical |
| Payment History | Review 12–24 months of records | 🟡 Important |
| Property Insurance | Confirm active hazard insurance | 🟡 Important |
| Tax Status | Check for delinquent property taxes | 🟡 Important |
| Occupancy Status | Owner-occupied, rented, or vacant? | 🟢 Helpful |
Warning: Never skip the O&E report and allonge chain. A $150 report can save you from a $50,000 mistake.

What Happens After I Buy the Note?
Congratulations — you are now the lender. Here is your post-closing checklist:
- Engage a professional note servicer to handle payment collection
- Notify the borrower in writing that the loan has been transferred (RESPA requirement)
- Record the assignment of mortgage in the county where the property is located
- Confirm hazard insurance is in place with your servicer as the mortgagee of record
- Set up your accounting — track payments received vs. your basis for yield tracking
- Review the first servicer statement to confirm payments are applied correctly
- Decide on your exit strategy: hold to maturity, sell at premium, or re-perform and flip
Passive investor note: With a professional servicer, you receive monthly ACH deposits and periodic reports. You never speak to the borrower directly.
