A lot of small-bay flex owners operate on handshake deals and month-to-month arrangements. The tenant’s been there for five years, pays on time, no complaints. Why bother with a formal lease?

I’ll tell you why: because it costs you money when you sell.


  • Identify all month-to-month tenants: Walk through your rent roll and flag every tenant on month-to-month or informal arrangements. This is your action list.

  • Approach tenants with lease offers: Start conversations 6-12 months before you plan to sell. Most will sign if the terms are reasonable and they’re planning to stay.

  • Include rent bumps in new leases: Structure new 3-year leases with 2-3% annual increases. These automatic bumps are valued more highly than flat leases.

  • Document everything: Keep signed lease copies, rent roll history, and any communications about the conversion. Clean documentation supports the higher value.

The buyer’s perspective

When I look at a flex park, I want to see signed leases with defined terms. Three years minimum, five is better. NNN structure. Annual rent bumps. A month-to-month tenant is income I can’t count on. They could leave next month. I have no legal mechanism to hold them to a rate or a term.

Month-to-Month vs. 3-Year Lease Impact

On the same 10-unit flex building with $100K NOI, here’s what the difference looks like:

  1. Month-to-Month version: $100K NOI at 8.5% cap = $1.18M valuation
  2. 3-Year Lease version: $100K NOI at 7.5% cap = $1.33M valuation
  3. Value difference: $150K just from lease structure (income identical)

A building where all ten tenants are on month-to-month arrangements gets a higher cap rate than the same building with the same tenants on 3-year leases. The income is identical today. The risk is totally different. I might put a 7.5 cap on the leased version and an 8.5 cap on the month-to-month version. On $100K of NOI, that’s the difference between a $1.33M building and a $1.18M building. $150K of value, gone, just because you didn’t put leases in place.

The fix

If you’re thinking about selling in the next year or two, start converting your month-to-month tenants to formal leases now. Most tenants will sign a 3-year lease without much pushback, especially if you keep the rent reasonable. They like certainty too. And honestly, it protects you as well.

Thinking about selling?

Get a confidential opinion of value. No obligation.

    If a tenant won’t sign a lease, that tells you something about their commitment. Better to know now than to have them leave a month after you’re trying to sell the building.

    What about long-term month-to-month tenants?

    I hear this a lot: “He’s been here eight years, he’s not going anywhere.” Maybe. Probably. But a buyer can’t bank on your gut feeling. A tenant who’s been there eight years with no lease can still leave with 30 days notice. That’s the legal reality. And in a market like Charleston or Raleigh where there’s lots of competition for tenants, you don’t want to be in that position when selling.
