GP/LP Economics and Waterfalls

The Waterfall: How Profits Flow From Deal to Investor

The distribution waterfall is the formula that determines how cash flow and sale proceeds are divided among the GP and LPs. It is the single most important section of any operating agreement, and the one most investors skim past. Two deals with identical properties and identical returns can deliver vastly different outcomes to LPs depending on how the waterfall is structured. A GP-friendly waterfall can redirect hundreds of thousands of dollars from LPs to the GP. Understanding the waterfall is what separates informed LP investors from passive check-writers.

Walking Through a Real Waterfall

Deal: a 150-unit apartment complex purchased for $10M. Senior debt: $7M (70% LTV) at 5.5%, 30-year amortization. Total equity raised: $3M from LPs. GP co-invest: $150K (5% of equity). Annual net cash flow after debt service: $250,000. Step 1, LP preferred return: 8% on $2.85M LP capital = $228,000 to LPs. Step 2, GP preferred return: 8% on $150K GP capital = $12,000 to GP. Remaining cash flow: $250,000 - $228,000 - $12,000 = $10,000. Step 3, profit split on remaining $10,000: 70% to LPs ($7,000), 30% to GP ($3,000). Total annual distributions: LPs receive $235,000 on $2.85M invested (8.2% cash-on-cash). GP receives $15,000 on $150K invested (10.0% cash-on-cash). During the hold period, the economics look similar. The real divergence happens at sale.

The Sale: Where the Promote Pays Off

After 5 years, the property sells for $13.5M. The loan balance has amortized to $6.4M. Net sale proceeds after closing costs (2%): $13.23M - $6.4M = $6.83M available for distribution. Step 1, return of capital: LPs get $2.85M back. GP gets $150K back. Remaining: $3.83M in profit. Step 2, unpaid preferred return catch-up: if any preferred return went unpaid during the hold, it accumulates here. Assume all prefs were current. Step 3, profit split on $3.83M: 70% to LPs ($2.681M), 30% to GP ($1.149M). Total returns over 5 years. LPs invested $2.85M, received $1.175M in cash flow plus $5.531M at sale ($2.85M return of capital + $2.681M profit) = total of $6.706M. LP multiple: 2.35x on invested capital. LP IRR: approximately 19%. GP invested $150K, received $75K in cash flow plus $1.299M at sale ($150K return of capital + $1.149M profit) = total of $1.524M. GP multiple: 10.16x on invested capital. GP IRR: approximately 58%.

The Promote Creates Asymmetric GP Returns

The GP put in 5% of the equity but captured approximately 17% of total distributions. That gap is the promote in action. It is not theft. The GP found the deal, underwrote it, arranged $7M in financing, signed a personal guarantee or key principal obligation, managed $2M in renovations, oversaw the property manager for five years, coordinated the sale, and handled all investor reporting and K-1s. The promote compensates for that work and risk. For LPs, a 2.35x multiple and 19% IRR on a passive investment with no management burden is a strong outcome. Both sides can win. The question for LP due diligence is whether the promote structure is reasonable relative to the GP's contribution and the deal's risk profile. Industry standard is 70/30 or 80/20 above an 8% pref. If a GP is proposing 50/50 splits above a 6% pref with a 1% co-invest, the economics are tilted too far in their favor.

• Reasonable GP promote: 20-30% of profits above an 8% LP preferred return
• GP co-invest of 5-10% of equity signals skin in the game
• Multi-tier waterfalls (higher GP split at higher IRR hurdles) align interests at the top end
• Catch-up provisions: some waterfalls give the GP 100% of distributions after the LP pref until the GP 'catches up' to their promote share. This accelerates GP compensation.
• Clawback provisions: if final returns fall below the preferred return, the GP must return excess promote. Not all deals include this. Insist on it.

Read the Operating Agreement

Waterfall structures are not standardized. They vary deal to deal and sponsor to sponsor. Some waterfalls calculate the preferred return on invested capital. Others calculate it on committed capital (including capital not yet called). Some calculate it as a simple return, others as an IRR hurdle. Some include a GP catch-up, others do not. Some have clawback provisions that force the GP to return excess promote if the deal underperforms. Others let the GP keep everything distributed, even if the final return misses the pref. These differences can shift tens or hundreds of thousands of dollars between LPs and the GP. The waterfall is on pages 30-40 of the operating agreement. Read those pages. If you do not understand the waterfall, you do not understand what you are investing in.

The waterfall governs how every dollar of profit is divided between GP and LP. Preferred returns protect LPs on the downside. The promote rewards GPs for delivering strong returns. Reasonable structures use an 8% LP pref with a 70/30 or 80/20 split above the hurdle. Always model LP and GP returns across multiple scenarios. The operating agreement is the only document that matters. Read it.
