Case Study: 50.5% IRR on a Vacant Land Loan Modification

The Setup

This deal was a non-performing loan in senior position secured by vacant land. Vacant land is generally considered less desirable collateral than a single-family residence — there is no structure, no occupant, and typically less borrower attachment. But one critical detail changed the calculus: the borrower was current on property taxes.

A borrower who continues to pay taxes on a vacant lot is signaling they intend to keep it. That signal mattered more than the property type. The land was valued at $170,000, while the unpaid principal balance on the loan was just $3,471 — creating an enormous equity cushion and strong confidence that a loan modification was achievable.

The Deal Metrics

The equity position on this deal was extraordinary. Dividing the property's fair market value by the UPB yields an equity coverage ratio of nearly 49x — the loan balance was a rounding error compared to the land's value. Looking at it from the CLTV side, total debt was roughly 2% of the property's value. There was zero risk that the borrower was underwater.

The Resolution

The borrower had been through a rough patch — this was a 2019 deal, pre-pandemic — but was getting back to work the following month. He wanted to keep the lot, and with a $170,000 property securing a $3,471 debt, his motivation was obvious. Walking away from the land would mean forfeiting an asset worth nearly 50 times what he owed.

The investor and borrower agreed to a modification at $202.34 per month. At first glance, annualizing that payment and dividing by the $1,849 cost basis suggests a 131.32% annual yield — a headline number that looks spectacular. But that figure is misleading because it does not account for the time value of money. The borrower is not going to pay $202.34 per month forever. Once the principal balance is satisfied, the cash flow stops.

And that is exactly what happened. The borrower paid the modification to maturity — making every scheduled payment until the loan was fully satisfied. No refinance. No lump-sum payoff. Just steady monthly payments over 23 months until the balance hit zero. The total amount collected was $3,642.

The Numbers

The math tells the real story. The investor collected $3,642 on a $1,849 investment for a gross profit of $1,793 — approximately a 97% return on investment. But because the deal took 23 months to fully pay out, annualizing that return brings the IRR to 50.5%.

Here is the formula:

IRR = (Total Collected - Cost Basis) / Cost Basis / (Months to Exit / 12)

($3,642 - $1,849) / $1,849 / (23 / 12) = 50.5%

That 131% annualized yield calculated earlier? It assumed the borrower would pay $202.34 per month indefinitely — like a rental property generating perpetual cash flow. Mortgage notes do not work that way. Once the balance is paid, the income stream ends. If an investor had used the 131% figure to justify paying $5,000 for this loan, they would have lost money when the borrower made the final payment at month 23, never recouping the full investment.

The Takeaway

This deal illustrates two principles that every note investor should internalize.

First, always calculate your internal rate of return — not just your annualized yield. The difference between 131% and 50.5% is not a rounding error; it is the difference between understanding your investment and being dangerously wrong about it. Annualized yield on cost basis tells you what the deal looks like in a vacuum. IRR tells you what it actually returns when the deal exits. If you use the wrong metric to set your bid price, you can overpay to the point of losing money on a deal that superficially looked like a home run.

Second, current taxes are a stronger buy signal than property type. Most investors would skip a vacant land NPL without a second thought. But a borrower who pays property taxes on an empty lot is telling you something important: they value that asset and intend to keep it. That behavioral signal — taxes current, borrower engaged — is a better predictor of modification success than whether the collateral has four walls and a roof. Conversely, a single-family property where the borrower has stopped paying taxes is a weaker modification candidate despite being "better" collateral on paper.

A 50.5% IRR on an $1,849 investment will not change anyone's net worth overnight. But the principles at work — reading borrower behavior through tax payments, pricing the deal correctly, and measuring returns with the right formula — scale to any loan size. Master them on small deals, and the six-figure investments become a matter of execution, not guesswork.
