My seller owns the management company that manages his own 18-unit

The disclosure question probably depends on your state, but practically speaking nobody is going to hand that over voluntarily, so it is on you to ask every single time. A pre-underwriting checklist for anything above a four-unit should have "is the management company a third party" as line two, right after the rent roll date. The classic version is a 24-unit in Columbus where the owner's spouse runs the PM company and the fee is buried at 10 percent while everything else in Franklin County is running 5 to 5.5 percent. Normalizing that shaves about $38k off the adjusted NOI, which at a 7 cap is nothing like a rounding error. Your 12 percent figure, I would actually push back on a little, because even the inflated number might not capture the full picture. When a seller controls the management company the fee is sometimes the cleaner part. The real games are in the maintenance invoices and the landscaping and snow removal contracts, expenses that flow through the same related entity and never get scrutinized because people focus on the management line. In that same Columbus example the normalized NOI drops another $14k just from pulling three years of maintenance bills and seeing the same LLC name on half of them. Before you go back to your buyer I would request 24 to 36 months of actual bank statements and reconcile every expense line against who got paid, rather than stopping at what the fee percentage says.

A common version of this is a 12-unit in Dayton where the seller has a brother-in-law's landscaping company on the books at three times what any other crew in the area charges. The "it's already in the rent roll so it's accurate" defense never holds up once a buyer's attorney gets involved. What actually happens is the deal retraces or the seller eats a price cut equal to the capitalized difference, which on 18 units at a 7 cap can be thirty or forty grand easily. Disclosure law or not, you sent the sheet, so your credibility is the thing on the line now. I would call the buyer before he calls you, show him the restated NOI with 6 percent management, and get ahead of it rather than let him feel like he caught something.

In most states the disclosure obligation on related party management sits with the seller's broker rather than the wholesaler, and that distinction will not save the deal or the reputation with that buyer. What actually matters is that a sheet went out that now has to be walked back, and buyers remember that. Take a common version of it: a 9 unit in a market like Akron where the seller's property manager is his own LLC charging 10% while the going rate on the east side is 5.5%. That gets caught by calling two local PM companies before finalizing any expense column, which takes about 40 minutes. Regionally this matters a lot, because in tighter markets like Cleveland or Columbus where the same buyers see deal after deal, a corrected pro forma is a reputation hit that follows you into the next negotiation. Get the corrected numbers to your buyer before he asks again and own the mistake plainly. Restate the cap at the real 6% figure so he can underwrite clean.

There is rarely a clean resolution once the wholesaler tries to fix this after the sheet is already out. What tends to happen is the buyer assumes you either missed it or hid it, and once trust is gone the deal dies anyway even if the fee gets renegotiated down to 6% on paper, because now he is wondering what else is baked in wrong. Pull the trailing 12 from the management company's actual invoices before building anything, rather than the rent roll line item the seller hands over. A 6 point spread on 18 units, depending on gross rents, can be $15,000 or $20,000 a year in phantom expense pushing the NOI the wrong direction, and that moves the cap rate conversation by half a point easily. On a deal trading at a 7 cap that is real money misrepresented to a buyer you want to work with again. Related party disclosure belongs in the first seller call, asked flat out, before anyone touches a spreadsheet.

That 12% should flag immediately, Denver management is sitting at 7 to 8% right now.
