Tenant at my Tucson strip paid 11 months on time then went dark for 60 days and somehow the rent roll still showed current

What you found is a real due diligence catch, and the reasoning you used to walk away is sound.

A rent roll is a document the seller or their broker prepares. It lists each tenant, the space size, the monthly rent, and whether the tenant is current. It is not verified by anyone independent, and as you discovered, "current" can mean whatever the seller decides it means. A partial payment accepted in December, applied against two months of arrears, can technically zero out the balance as of that date and make the column say current. That is not fraud in most cases. It is just a document that tells you less than it appears to.

The thing worth naming for anyone else reading this thread: a rent roll is a starting point, not a conclusion. The check you ran, pulling actual bank statements, is exactly the right move. Deposit records show what money actually arrived and when. They also show partial payments, which rarely appear in the rent roll narrative.

The other piece you surfaced is the personal guarantee question. On a commercial lease, a personal guarantee means an individual, usually the business owner, is personally on the hook for the rent if the business stops paying. Without one, and with a local operator rather than a national credit tenant, your only recourse if she walks is the space itself and whatever is left in a security deposit. A funded build-out of $34,000 with no guarantee behind the lease is a real exposure, because that money is already spent and recovery depends entirely on finding a replacement tenant who wants the same configuration.

I'd ask: when you pulled those bank statements, did the seller cooperate or did you have to push for them?

The broker's defense is technically defensible and practically useless to you as a buyer, which is exactly the problem. A rent roll is a point-in-time snapshot, and nothing in its standard format requires the seller to disclose payment history, workout agreements, or partial settlements. The document showed a current balance. It was not wrong. It was just incomplete in a way that costs you money.

The assumption doing the most work in that $1.1M ask was that rent roll stability equals income stability. Those are different things. One tenant negotiating arrears down to a partial payment has already demonstrated willingness to default and renegotiate, which is a behavioral data point about how she treats her lease obligations. The $34,000 TI the landlord funded with no personal guarantee means the seller absorbed that cost and retained no recourse. If she vacates, you inherit a 1,100 square foot space with a 2019 nail salon build-out, which is a specialized improvement that narrows your re-tenanting pool significantly.

Your read on the other six tenants is the right instinct. One disclosed pattern in a seven-unit deal, only discovered because you pulled bank statements, is a sampling problem. You cannot price a center correctly if you are working from income data that has been smoothed by off-roll side agreements.

For any future multi-tenant retail deal, the standard request is 12 to 18 months of actual bank deposits alongside the rent roll, estoppel certificates from every tenant signed directly (bypassing the seller), and a specific disclosure request covering any payment plans, rent deferrals, lease amendments, or TI disputes in the prior 24 months. A clean rent roll with a dirty deposit history fails all four of those.

What did the LOI or PSA you were working from say about seller disclosure obligations? That clause is where this kind of gap either gets caught or stays buried.
