Reading a Rent Roll Like an Operator

Reading a Rent Roll Like an Operator

By Tanner Sherman, Managing Broker

The rent roll is the single most important document in any acquisition. It is also the most lied to.

Sellers and brokers know how to present a rent roll in the best possible light. They show contract rent, not collected rent. They hide concessions in fine print. They list units as occupied that have not paid in three months.

Here is how I actually read one.

Contract Rent vs Collected Rent

The first column most people look at is contract rent. That is the wrong column. The right column is what each tenant actually paid in the last three to six months.

If contract rent shows 1100 dollars but the tenant has paid 850 dollars for the last four months because of a concession or a quiet rent reduction, your real income is 850. Underwriting at 1100 will blow up the deal.

Pull the bank deposits. Pull the property management software ledger. Reconcile them against the rent roll. Any difference is a red flag.

Lease Expiration Stacking

Look at when every lease expires. If 60 percent of the leases roll in the same 90 day window, you have a turnover bomb.

A property with staggered expirations gives you steady cash flow. A property with stacked expirations forces you to retain everyone at the same time or face 60 percent vacancy in one quarter.

This is the kind of detail that does not show up on the marketing flyer. It shows up the first quarter you own the building.

Below Market Rents and the Real Upside

Compare every unit rent to market comps. If the property is at 950 dollars and market is 1175, you have 225 dollars of upside per unit per month. That is real money.

But understand why the rents are below market. Sometimes it is a lazy seller. Sometimes it is functional obsolescence the photos do not show. Sometimes it is a tenant base that physically cannot pay market.

Below market rents are only valuable if you have a credible path to market. If the units need 12 thousand dollars of capex each to justify the new rent, factor that in. If the tenant base needs to roll over, factor in turnover costs and vacancy loss.

Concession and Loss to Lease

Read every line item. If a unit shows free rent for the first month of the lease, the trailing 12 income is misleading.

Loss to lease is the gap between in-place rent and market rent. It is supposed to represent upside. But if loss to lease has been growing for two years and the seller never raised rents, that tells you the operator was either disengaged or had a reason. Find out which.

Delinquency and Eviction Trail

Ask for the delinquency report. Not the rent roll, the delinquency report. They are different documents.

Anyone over 30 days delinquent is a liability you are about to inherit. Anyone in active eviction is essentially a vacant unit being lied about on paper.

Underwrite those units as vacant. Build a turnover cost into your model. Add legal fees for the eviction process. If the seller pushes back on this, walk away. You are about to learn an expensive lesson the easy way.

What the Rent Roll Does Not Tell You

A good rent roll read is the start. It does not tell you the condition of the unit. It does not tell you the tenant payment history. It does not tell you what the local rental comps actually support.

That is why we walk every unit. Pull every payment history. Run our own comps. A rent roll is one input. The deal is built on a stack of them.
