Subscription Lines of Credit: How a Fund Bridges Capital Calls and What It Really Does to Your IRR

A fund can close on a property before it ever calls your capital. That is not a typo. It is a subscription line of credit, and almost no one explains it to limited partners before they sign.

We have written about capital calls, waterfalls, clawbacks, and GP catch-up provisions in detail. This is the piece that was missing: the credit facility sitting quietly behind the capital call itself, changing both the timing of your cash and the math on the return you think you are earning.

What a Subscription Line Actually Is

When investors commit capital to a fund, they are not wiring money on day one. They are signing a commitment: a promise to fund capital calls when the general partner issues them. A subscription line of credit is a facility, usually from a bank, that lets the fund borrow against those unfunded commitments.

Think of it like a line of credit secured not by the real estate, but by the LPs' promises to pay. The bank looks at the quality and creditworthiness of the investor base, not the building. The fund draws on the line to close a deal immediately, then calls capital from LPs later to pay the line down.

Why GPs Use One

The honest reason is speed and certainty of close. Sellers and brokers favor buyers who can close in days, not weeks. Waiting thirty to forty-five days to collect a capital call from forty different LPs before wiring a seller is a real competitive disadvantage in a tight market. A sub-line lets the GP act like an all-cash buyer, close fast, and worry about the mechanics of calling capital afterward.

There is also an administrative benefit. Instead of calling capital in small, frequent increments every time a deal needs funding, a GP can draw the line for several acquisitions and then issue one consolidated capital call. Fewer wires, fewer administrative headaches for LPs.

Both are legitimate. The part worth sitting with is what the delay does to the number on your statement.

The IRR Problem Hiding Inside the Timing

IRR is a function of cash flows and time. It rewards capital that is deployed for a shorter period and still produces the same return. A subscription line changes when your capital is deemed "in" the deal, not when the fund's capital is actually working.

Here is the mechanic. The fund draws the line and closes the property on day one. The clock on the asset's performance starts immediately. But your capital commitment is not called until, say, month four, when the GP pays down the line. From the LP's side of the ledger, your money was only "at work" for a shorter window than the asset itself was actually operating.

Run that forward through a full fund life and the effect compounds. A fund that uses a subscription line can show a materially higher IRR to its LPs than a fund with an identical return profile that calls capital upfront and deploys it directly into deals, simply because the LP-level clock started later. The underlying real estate performance can be identical. The reported number is not.

This is not fraud. It is disclosed in the fund documents, and sophisticated institutional LPs have debated it for years. But it means the IRR you see on a pitch deck or a track record summary may be measuring something closer to "return once the bank's money stopped working for us" rather than "return from the day the asset started generating income."

What to Ask Before You Commit

If a fund uses a subscription line, you are entitled to clarity on a few specific things before you sign a commitment.

Is the reported IRR levered at the LP level, and is it net or gross of the subscription line's effect on timing? Ask specifically whether the track record IRR would look different calculated from the date of acquisition versus the date of the actual capital call.

What is the maximum size and duration of the line relative to total commitments? A line used for thirty to sixty days to bridge a closing is a very different animal than a line left outstanding for a year.

Who bears the interest cost on the line, and how is it allocated? That cost usually comes out of fund-level returns before anyone sees a distribution.

Does the fund disclose both a levered and unlevered IRR in its reporting? The better-run funds will show you both, so you can see the gap.

None of this means a subscription line is a red flag. Used well, it is a professional tool that gets good deals closed on competitive terms. The red flag is a GP who cannot or will not explain how it affects the number on your statement.

We think the LPs who ask these questions before they commit end up the most comfortable LPs four years in. How a sponsor thinks about capital timing, leverage placement, and fee alignment before a single dollar is committed tells you most of what you need to know about how they will treat you after it is.
