A smaller mortgage note fund can offer advantages that larger funds struggle to replicate — greater selectivity, faster decision-making, closer alignment between the manager and investors, and access to smaller deals that institutional buyers overlook. That does not make small funds automatically “safer” or higher-returning. Larger funds bring their own strengths in resources and diversification. This guide explains where smaller note funds have an edge, what the research on fund size actually shows, the tradeoffs to weigh, and how these principles apply to Labrador Lending’s Integrity Income Fund.

The instinct that “bigger equals safer” is understandable, but in the mortgage note market — where sourcing quality loans and moving quickly matter — scale is not always an advantage. If you’re still getting oriented, our guide to what a mortgage note fund is and how it generates monthly income covers the fundamentals. The more useful question here is not which is better, but which strengths matter most for your goals.

What Is a Mortgage Note Fund?

A mortgage note fund is a pooled investment vehicle that acquires and manages mortgage notes — the legal instruments in which a borrower promises to repay a real estate loan. Instead of buying individual notes directly, investors contribute capital to the fund, which sources, underwrites, and manages a portfolio of notes on their behalf and distributes income generated by the underlying loans.

Because individual mortgage notes are relatively illiquid and require specialized due diligence, the size of the fund managing them influences how it sources deals, how quickly it can act, and how disciplined it can remain — which is exactly where the small-versus-large question becomes meaningful.

Do Smaller Funds Actually Perform Better?

Research across the broader fund industry suggests that returns can erode as funds grow — a pattern economists call diseconomies of scale. In a widely cited study published in the American Economic Review, Chen, Hong, Huang, and Kubik (2004) found that fund returns tend to decline with fund size, and that this effect is most pronounced among funds that invest in small, illiquid assets.¹ Mortgage notes fall squarely into that illiquid category.

That finding has held up in more recent work. Pástor, Stambaugh, and Taylor (2015), in the Journal of Financial Economics, found decreasing returns to scale in active management, with a fund’s ability to outperform its benchmark declining as scale increases.² A 2022 robustness study in the Critical Finance Review re-tested that evidence using robust regression methods, confirmed scale diseconomies at both the fund and industry levels, and rejected constant returns to scale.³

The intuition is straightforward. A very large fund has to put a great deal of capital to work to move the needle. That pressure can push managers to buy more deals — including mediocre ones — bid up prices, or drift into assets outside their core expertise. A smaller fund deploying a fraction of that capital can afford to wait for exceptional opportunities and pass on the rest.

Two important caveats keep this honest. First, the research above studies mutual funds, not mortgage note funds specifically, so it is directional evidence rather than a guarantee. Second, size is only one variable — manager skill, underwriting discipline, and risk controls matter far more than a headline dollar figure. As one balanced way to frame it: larger funds often benefit from greater resources and diversification, while smaller funds may benefit from greater flexibility, selectivity, and alignment.

9 Advantages of a Smaller Mortgage Note Fund

When a smaller note fund is well run, its size can translate into concrete advantages for the right investor:

1. More selective acquisitions

A smaller fund does not need to deploy millions every month just to keep capital working. It can pass on average deals and wait for exceptional ones. The message is simple: a fund that only needs a handful of great loans is under less pressure than one that must buy dozens of average ones to stay fully invested.

2. Access to opportunities larger funds overlook

Many attractive note purchases — individual first liens in the roughly $40,000–$150,000 range, one-off notes, and small pools — are simply too small to matter to institutional buyers. Large funds often ignore them because they are not material to a multi-hundred-million-dollar portfolio. A smaller fund can pursue these overlooked opportunities profitably. Because the secondary note market is fragmented rather than centralized, sourcing notes takes relationships and legwork — which is exactly the kind of work that rewards a focused team.

3. Greater agility and speed

Smaller funds can react quickly: evaluate a note, bid, and close on a compressed timeline, or adjust strategy as market conditions shift. Large organizations frequently require investment-committee approval, multiple sign-offs, and lengthy due-diligence processes that slow them down and can cost them the best deals.

4. Shorter commitment periods and more accessible minimums

This advantage is often overlooked, and it flows directly from the size of the loans a smaller fund buys. Smaller-balance notes are easier to sell individually than large institutional pools, which gives a smaller fund more practical flexibility to return investor capital when it is requested. Many private debt funds ask investors to commit for three, five, or more years, and set minimums well above what an individual investor wants to allocate to a single position. A fund working with smaller assets can often offer a shorter commitment period and a lower entry point.

Specific to the Integrity Income Fund: IIF has a 12-month commitment period and a $25,000 minimum investment. After the commitment period, an investor may request a redemption. The fund’s governing documents allow up to 90 days to fulfill that request; in practice, the fund has historically returned investor capital in about three weeks. Past experience does not guarantee future redemption timing, and terms are governed by the fund’s official offering documents.

5. Hands-on, direct asset management

There is a meaningful difference between a fund that manages its assets directly and one that allocates capital to other operators. Some larger funds joint-venture with third-party operators or invest through other managers, which adds a layer between the investor’s capital and the person making decisions on individual loans. A smaller fund can keep asset management in-house, with the principal personally involved in decisions on each note — how to approach a workout, when to modify, when to sell.

Specific to the Integrity Income Fund: IIF handles asset management directly rather than outsourcing it, while overseeing licensed third-party servicers for loan servicing.

6. Stronger manager alignment

Managers of smaller, founder-led funds often have meaningful personal capital and reputation on the line. Research on manager “skin in the game” supports the intuition that alignment matters: Jia and Wang (2017), in the Journal of Corporate Finance, found that fund performance improves as the manager’s own capital commitment rises, because it better aligns the manager’s incentives with investors’.⁴ Across private funds, a large-sample analysis of 1,503 funds found the average manager commitment was about 3.5% of the fund.⁵

7. Direct access to leadership

Instead of routing questions through an investor-relations department, investors in a smaller fund can often speak directly with the person managing their money. Questions get answered quickly, and communication feels personal — something many retirees and income-focused investors value highly.

8. Greater transparency

Smaller firms frequently provide more granular communication: detailed updates, specific examples of investments, educational content, and direct conversations. Investors tend to know what is actually happening inside the portfolio rather than receiving only high-level summaries. Reporting frequency is a useful signal — quarterly investor reporting is the more common standard across private funds, so monthly reporting represents a meaningful step up in visibility.

Specific to the Integrity Income Fund: IIF sends investor updates monthly.

9. Discipline and less “style drift”

Large inflows can pressure managers to loosen underwriting standards or deploy capital outside their original expertise — for example, buying unfamiliar asset types simply because there are not enough of the fund’s core assets to absorb the cash. A disciplined smaller fund can stay in its lane, and some intentionally limit growth to preserve their strategy, since sourcing and returns can change as a fund scales.

What Are the Tradeoffs? Where Larger Funds Have Advantages

Intellectual honesty matters here, and overstating the case for small funds would undermine credibility. Larger funds offer genuine benefits that smaller funds cannot always match:

• Diversification: More capital can spread risk across more notes, geographies, and borrower profiles.
• Resources and staffing: Larger teams bring specialized underwriting, legal, and servicing-oversight capacity.
• Operational depth: Established institutional processes and redundancy can reduce key-person risk.

Smaller funds carry their own risks — less diversification, thinner staffing, and greater reliance on the founder. That is why due diligence should focus on the manager’s track record, servicing arrangements, reporting quality, and risk controls, regardless of fund size. Size is a lens, not a verdict. Our guide on how to evaluate a mortgage note fund walks through the specific questions to ask any manager before investing.

How This Applies to the Integrity Income Fund

The following details are specific to Labrador Lending’s Integrity Income Fund (IIF) and should not be generalized to all mortgage note funds. As a boutique, founder-led fund, IIF is built to lean into the strengths a smaller fund can offer while keeping its structure straightforward:

• No fund-level leverage. The fund does not borrow at the fund level.
• 12-month commitment period. Shorter than the multi-year lock-ups common among private debt funds.
• $25,000 minimum investment. A lower entry point than many institutional-scale funds require.
• Both performing and non-performing notes. IIF holds residential mortgage notes across both categories rather than a single narrow slice.
• Direct asset management. IIF manages its assets in-house rather than outsourcing that role, while overseeing licensed third-party servicers for loan servicing.
• Monthly investor updates. More frequent than the quarterly reporting common across private funds.
• Direct access to leadership. Investors can engage directly with the fund’s management rather than a call center.
• Disciplined growth. The focus is on sourcing quality notes, not deploying capital for its own sake.

Many investors participate through a retirement account — see our guide to investing in a mortgage note fund with a self-directed IRA, where a custodian administers the account while the fund holds and manages the underlying note assets.
