What Is a 506(c) Offering and Why It Matters for Accredited Investors
506(c) offerings let sponsors publicly advertise private raises — but only to verified accredited investors. Here is what that means for your capital and your protections.
Investors routinely compare deals using different return metrics — and reach opposite conclusions. Here is how to read IRR, equity multiple, and cash-on-cash correctly, and when each one tells the real story.
Most real estate deals are presented with at least two or three return metrics — and sponsors know which one flatters their numbers most. The problem is that IRR, equity multiple, and cash-on-cash each measure something fundamentally different, and leading with the wrong one can make a mediocre deal look institutional or make a solid cash-flow play look weak. Understanding what each metric actually captures — and where each one breaks down — is one of the most practical skills any accredited investor can develop.
Before comparing deals, you need a precise definition of what each number represents. These are not interchangeable. They answer different questions.
IRR is the annualized rate at which your invested capital grows, accounting for the timing of every cash flow — distributions received during the hold period and the return of capital at exit. Mathematically, it is the discount rate that sets the net present value of all cash flows to zero.
The critical word is timing. A deal that returns $200,000 on a $100,000 investment in three years produces a materially higher IRR than the same dollar return delivered over seven years — even though the total dollars returned are identical. IRR rewards speed.
This makes IRR the most useful metric when comparing deals with different hold periods or different distribution schedules. A value-add multifamily deal that forces appreciation and exits in four years will produce a different IRR profile than a stabilized asset held for eight years, even if the equity multiple is similar.
Where IRR breaks down: it assumes that all interim distributions are reinvested at the same IRR — an assumption that rarely holds in practice. According to the Urban Land Institute's foundational work on real estate investment analysis, this reinvestment assumption is one of the most commonly misunderstood limitations of IRR in real estate underwriting. A deal with a 22% projected IRR is not necessarily better than one projecting 17% — especially if the 22% deal has a thin distribution schedule and a back-loaded exit.
The equity multiple answers a simpler question: for every dollar you put in, how many dollars do you get back?
A 2.1x equity multiple means a $100,000 investment returns $210,000 in total — including your original capital. The formula is straightforward: total distributions divided by total equity invested.
Equity multiple is indifferent to time. It does not care whether that 2.1x arrives in three years or nine. This is both its strength and its limitation. For investors who care primarily about total wealth creation — how much capital am I walking away with? — the equity multiple is a cleaner signal than IRR. For investors comparing a three-year deal to an eight-year deal, it tells them very little about efficiency.
Equity multiple becomes most meaningful when paired with hold period. A 2.0x over four years is a fundamentally different outcome than a 2.0x over ten years. Always ask both numbers together.
Cash-on-cash measures the annual pre-tax cash income generated by the investment relative to the total equity deployed. It is the simplest metric and the most operationally grounded.
If you invest $100,000 and receive $7,000 in distributions in year one, your cash-on-cash return is 7%. It does not account for appreciation, depreciation, or the eventual equity realized at sale — only the current income the asset is generating.
This is the metric that tells you whether a deal actually pays you while you hold it. For investors who have liquidity needs, income requirements, or tax strategies built around current distributions, cash-on-cash is the most honest measure of how a deal performs in the present tense.
AirDNA's analysis of short-term rental investments identifies cash-on-cash as one of the most operationally relevant metrics for evaluating STR performance, precisely because it isolates current income from speculative appreciation assumptions.

This is where investor education matters most. A sponsor controls which metric headlines the pitch deck — and a sophisticated sponsor knows exactly which one makes their deal look best.
Consider two hypothetical deals presented to the same investor with $150,000 to deploy.
Deal A — Value-Add Multifamily, 4-Year Hold
Deal B — Stabilized Multifamily, 8-Year Hold
The equity multiples are nearly identical — 1.85x versus 1.81x. An investor who evaluates only the equity multiple sees two deals that are essentially equivalent. But they are not.
Deal A produces nearly double the IRR, which means the capital is working harder and returning faster. Deal B produces more than double the annual cash-on-cash — which means the investor receives meaningful income throughout the hold rather than waiting for a back-loaded exit.
Now consider the investor's actual situation. If they are in a high-income year and need current distributions to offset living costs, Deal B's 7% cash-on-cash is far more valuable than Deal A's 3.25%. If they are a 42-year-old accumulator who wants to compound capital aggressively and has no liquidity need, Deal A's 18.2% IRR is the better choice.
The math does not change. The investor's context determines which number is actually relevant.
IRR is the most manipulable of the three metrics. Because it is sensitive to timing, a deal with an aggressive exit assumption — even a slightly optimistic cap rate at sale — can produce a dramatically higher projected IRR without changing the underlying operations at all.
A deal projecting a 5.5% exit cap rate will show a materially higher IRR than the same deal underwritten to a 6.0% exit cap rate. The operations are identical. The projected IRR is not. CoStar's ongoing analysis of cash flow dynamics in current real estate markets reinforces that many operators are leaning into cash-flow-focused underwriting precisely because appreciation-driven IRR projections have become harder to defend as cap rates have risen.
When a sponsor leads with IRR, ask: what exit cap rate assumption drives that number? What happens to the IRR if exit cap rates expand by 50 basis points? If the IRR collapses under modest stress, the headline number is doing a lot of work that the deal itself may not support.
There is no universally correct metric. The right one to weight most heavily depends on the deal structure, the hold period, and the investor's specific priorities.

Institutional investors do not pick one metric. They use all three as a cross-check — then stress-test the underwriting assumptions behind each one.
According to Apollo Global Management's publicly disclosed investment criteria in SEC filings, institutional funds evaluate private equity investments against return targets that include both IRR thresholds and equity multiple minimums simultaneously — precisely because each metric captures a different dimension of risk and return. No single number is sufficient.
For individual accredited investors, the same principle applies. The discipline is not memorizing which metric is "best" — it is understanding what each one measures, recognizing when a sponsor is leading with the most favorable metric rather than the most informative one, and calibrating accordingly against your own investment profile.
Selly's investor matching process is built on exactly this framework. Every deal reviewed for the accredited investor deal matching platform is evaluated across all three return dimensions before it reaches an investor's inbox — because a number that looks strong in one metric can be hiding material weakness in another. The 360-degree verification process exists to surface those gaps before they reach the decision stage.
For more on how Selly evaluates deals before they reach investors, the post on how Selly screens a deal before it reaches an investor covers the specific criteria applied at each stage of review.
IRR, equity multiple, and cash-on-cash are tools — not rankings. The investor who understands what each one measures, recognizes when a number is being used to flatter rather than inform, and knows which metric aligns with their own liquidity needs and wealth goals is the investor who makes decisions grounded in the math rather than the pitch.
If you are an accredited investor evaluating deal flow and want to understand how Selly applies this framework to every opportunity that reaches the platform, the accredited investor deal matching program is built for exactly this kind of disciplined evaluation. Every deal is reviewed against all three return metrics before it is matched to an investor profile.
