The thing that doesn't show up in a fund comparison is the liability stack. A decent engagement maps how a specific acquisition sits inside your existing structure, entity type, debt position, cross-collateralization risk, what happens to your other assets if that deal goes sideways. VNQ doesn't care about your balance sheet. A real analysis does, and it changes the answer.
What I'd want to know before paying anyone again is whether they modeled an actual exit. Not IRR in the abstract, but the specific tax drag on a sale in year five given your basis and your state. If the deliverable doesn't have a number attached to your situation, you bought an opinion, not an analysis. Six weeks and no scenario modeling is the tell.
