18 percent management fee on an 18-unit and the owner thought he was doing fine

The assumption doing the most work in those 5-6 percent projections is that the GP's time has no cost because it isn't written on an invoice. That retired owner made the same error in reverse, and the arithmetic was identical.

Where I'd push on your read: a syndicator projecting 5-6 percent on a small asset probably intends to hire third-party management and is understating the fee, not hiding sweat equity. The more common distortion is stacking an asset management fee on top of a property management fee and counting only one of them in the pro forma expense line. Worth asking any sponsor to show both numbers separately before you read the preferred return figure.

What was the cap rate the buyer underwrote it at, and did they model management at market rate or at the seller's actual zero?

The ledger observation is sharp, and the assumption it names deserves more attention than it usually gets.

The number doing the most work in a small-asset pro forma is almost always management expense, because it sits upstream of everything: NOI, cap-rate valuation, debt coverage, and the spread a sponsor claims as promote. When a GP models 5 or 6 percent on a 20-unit or under, they are usually benchmarking against institutional management contracts written for 100-plus unit assets where scale absorbs overhead. That economy does not exist at 18 units. The per-door cost of coordination, maintenance dispatching, leasing, and reporting does not compress proportionally when you cut the unit count by 80 percent.

The risk you did not name is what happens when that underwriting goes into an LP deck. An LP sees 6 percent management on a small asset and reads it as conservative. The sponsor may genuinely believe it is conservative. Neither party has stress-tested what the number looks like when a professional third-party manager quotes 10 to 12 percent, adds a leasing fee, and charges separately for maintenance oversight, which is the actual market rate for sub-25-unit assets in most metros. Confirm current market rates with local property management operators, not national benchmarks, before anchoring any figure in a model.

Your seller was not accounting for his own time at any rate. A syndicator doing the same thing in a pro forma is making a structurally identical error, except they are doing it with other people's capital and a promote on top.

The harder version of this for a sponsor audience: if the management fee line is where the deal works, the deal does not work.

What asset size do you see this underwriting pattern on most often, and are sponsors on those deals co-investing meaningful capital alongside LPs?

That 5-6 percent projection on a small asset isn't optimism, it's just not knowing what labor actually costs. I ran numbers on a fourplex here in Memphis last spring and the realistic management load, once you price the owner's time at anything close to market rate, was sitting closer to 14 percent before a single vacancy hit. What was the per-unit rent on that 18-unit, because I'm wondering if the math would've looked different to him if he'd been collecting $1,400 a door versus $800.

The gap between 5 percent on paper and what management actually costs on a small asset almost always lives in the unbundled line items: maintenance coordination fees, lease-up fees, renewal fees, and the owner-paid vendor markups that a third-party PM folds into their base rate. A syndicator projecting 5 to 6 percent on an 18-unit is usually quoting the base management fee and parking the rest in a separate repairs reserve or calling it a capital expense, which makes the pro forma look tighter than it is. When you add the coordination fee (often 10 percent of each repair invoice), the lease-up fee (commonly one month's rent per turn), and a renewal fee on top, the all-in cost on a Class B or C small multifamily with normal turnover lands closer to 11 to 14 percent of collected rent before anyone touches a toilet themselves. The structure that wins on a small asset is a flat-fee PM contract with a capped vendor markup, because percentage-based fees scale with rent growth and punish the deal right when it looks like it is performing.

The seller's ledger problem and the syndicator's pro forma problem are actually the same error from opposite directions: both treat management as a single line when it is four or five lines that only collapse into one when nothing goes wrong. Where the two structures diverge is in who absorbs the variance. A self-manager absorbs it invisibly in time and mileage, which is why that retired seller never knew he was at 18 percent. A syndicator absorbs it visibly in distributions, but only after the asset management fee and the preferred return are paid, so limited partners feel it first. The question worth pressing on any small-asset syndication deck is whether the management fee projection includes lease-up and coordination costs or excludes them, because

The 5 or 6 percent line in a small-asset pro forma almost always comes from a quote the sponsor got from a third-party manager who was trying to win the business, not from what the manager will actually charge once the asset is under contract and the sponsor has no leverage to renegotiate. Take an 18-unit collecting $18,000 a month in gross rents. At 6 percent the pro forma shows $1,080 going to management. A realistic fee for a building that size in most markets runs 8 to 10 percent, plus a leasing fee of one month's rent per new tenant, plus a maintenance markup that can run 15 to 20 percent on top of whatever the vendor charges. If you turn four units in a year at a half-month leasing fee and average $400 in marked-up maintenance per unit per month, you are closer to $3,200 a month in total management-related drag, not $1,080. That difference is about $25,000 annually, which at a 6-cap changes your valuation by over $400,000 on a stabilized basis. Sponsors who project 5 or 6 percent are either using a quote as a number, or they are assuming self-management, which creates a whole different set of undisclosed conflicts.

What your seller's notebook actually illustrates is that self-management has a real cost that never shows up as a line item, and when a sponsor plans to manage in-house and charge the fund a management fee, the question is whether that fee is arm's-length or manufactured margin. The document that settles it is the property management agreement, specifically whether it was negotiated with the GP on one side and an independent party on the other, or whether the GP signed it with himself. On a small asset where the sponsor

The risk that follows from that undercount is in the refinance or sale waterfall: if the actual operating history shows management expense well below true cost, the stabilized NOI looks cleaner than it is, and a buyer's lender will underwrite to that number, which means the appraisal comes in higher than the asset can support once a professional manager steps in at market rate.

What rate did your buyer's lender actually use for management expense in the appraisal, and did anyone push back on it?

What I keep seeing in Dayton and Akron packages is 7 percent, not 5, and operators acting like that extra two points makes them conservative. On a 18-unit running maybe $18k gross a month that is still $1,260 and change, and nobody is finding a competent third-party manager for that in a secondary market right now. The ones actually picking up phones and processing maintenance tickets in those markets are closer to 10, and that is before the lease-up fee they bury in the addendum. The seller in this story was essentially subsidizing the asset with his own labor without knowing it, which means the trailing income looked cleaner than it was, which means anyone who bought on a cap rate without adjusting for real management cost paid for his ignorance.

What was the actual gross rent on that 18-unit when you underwrote it for your buyer?
