Commercial property with below-market rent can be an opportunity or a risk, depending on why the rent is low and how soon you can change it. It is an opportunity when leases expire soon, rent steps are scheduled, or the building can be repositioned so that rents rise toward the market. It is a risk when long leases lock in low rent for years, tenants have renewal options at fixed prices, or the rent is low because the space is weak. Check the lease dates before you pay for upside.
What "below market" actually means
Below-market rent means a tenant pays less than what comparable space would rent for today. Sellers often highlight this as "upside," meaning you can raise rents after you buy. That works only if you can legally raise the rent and the market will pay it. Market rent depends on the submarket, building quality, condition, location, size, lease structure (NNN, modified gross, full service) and the date. It varies by property, so it must be measured with current comparables from CoStar, a broker's analysis or an appraisal, not from asking prices alone.
Compare like with like. Rent quoted on a NNN basis cannot be compared to a full-service rate without adjusting for expenses. Our guide to the triple net lease explains the difference.
Why rent can be below market
- Old leases: Rent was set years ago and has not kept up with the market.
- Long-term, fixed leases: The tenant negotiated a long term with small or no increases.
- Related-party or legacy deals: The tenant is a relative, partner or longtime occupant.
- Concessions: Free rent or high tenant improvements were traded for a lower rate.
- Weak space: The location, condition or layout limits what tenants will pay.
- Management gaps: The owner never pushed rents.
The reason matters. If it is an old lease that is about to expire, the upside may be real. If the building itself is the problem, a rent increase may drive tenants out.
When below-market rent is an opportunity
- Near-term expirations. Leases ending within a window you can manage let you re-lease at market rent.
- Scheduled increases. Contractual rent steps raise income without renegotiation.
- Value-add potential. Renovations, better management or new marketing can justify higher rents. See how to market a commercial building for lease.
- Strong tenant demand. The location shows leasing activity and low turnover risk, confirmed by market data rather than hope.
- Entry price reflects the current income. You are not paying for rent growth that may never arrive.
When it becomes a risk
- Locked-in leases. A long lease with a low fixed rent limits your income for the whole term.
- Renewal options at fixed or capped rent. The tenant can renew at an old rate even after the base term ends.
- Tenant rollover cost. Raising rent may trigger vacancy, leasing commissions, tenant improvements and downtime, which can erase the gain.
- Tenant credit. A tenant who pays low rent but is financially weak is a double problem.
- Paying for the upside. If the seller prices the property on projected rents, you pay today for income you do not have.
- Financing limits. Lenders underwrite in-place income, which affects how much you can borrow.
Opportunity or risk: a quick comparison
| Situation | Likely outcome | What to verify |
|---|---|---|
| Lease expires within a few years, tenant has no option | Opportunity if the market supports higher rent | Market comparables; tenant demand; rollover costs |
| Long lease, small annual increases | Risk: income stays low | Remaining term; renewal options; escalation clause |
| Renewal option at fixed rent | Risk: cap on upside | Exact option language and notice dates |
| Space is dated or poorly located | Risk: low rent may be the real market | Condition; vacancy in comparable buildings |
| Strong location with renovation potential | Opportunity with capital cost | Budget; timeline; permitting |
How to analyze it step by step
- Build the rent roll. List every tenant, rent, term, increases, options and expense structure. Our rent roll guide shows how.
- Estimate market rent. Use current lease comparables, not just asking rents, and adjust for size, quality and lease type.
- Measure the gap. Compare in-place rent with market rent for each tenant and note when each lease can reset.
- Cost the transition. Include vacancy time, commissions, tenant improvements, free rent and legal costs.
- Underwrite the current income. Value the property on in-place net operating income. Treat upside as a possible bonus. See how to calculate NOI and what is a good cap rate.
- Stress test. Run a case where rents do not rise, and one where a key tenant leaves.
Example (hypothetical): a 20,000 square foot building is leased at $10 per square foot NNN, or $200,000 a year, and comparable space is estimated at $13 per square foot, or $260,000 a year. The gap is $60,000 a year, which, at a hypothetical 7 percent cap rate, implies about $857,000 of potential value ($60,000 divided by 0.07). But if the lease runs eight more years with 2 percent annual increases, you receive little of that for a long time, and a buyer paying for it up front takes the risk. These figures are illustrations only.
Lease terms that decide the upside
- Expiration date and any early termination rights.
- Renewal options: fixed rent, fair market value, or capped increases.
- Rent escalations: fixed steps or percentage increases.
- Assignment and subletting rights.
- Who pays expenses and whether recoveries are capped.
- Rights of first refusal or purchase options held by the tenant.
Review each lease with your attorney. Tenant estoppel certificates should confirm the terms the seller describes. If tenants hold above-market-value renewal options, the lease language often decides whether the opportunity exists.

Getting the data you need
Market rent is the hardest number to pin down. A broker with access to CoStar can pull comparable leases and sales, an appraiser can give an independent opinion, and your own leasing experience in the corridor helps. Northern Virginia submarkets such as Tysons, Reston, the Dulles corridor, Manassas and Woodbridge behave differently, so a comparison from one area may not apply to another. Our guide to determining the market value of commercial property covers valuation methods.

Frequently asked questions
What does below-market rent mean in commercial real estate?
It means a tenant pays less than comparable space would command today. Measuring it requires current lease comparables adjusted for size, condition, location and lease structure.
Is buying a property with below-market rent a good investment?
It can be if leases expire soon and the market supports higher rent, and if the price reflects current income. It is riskier when leases are long, renewal options are fixed, or the space is weak.
How do I raise rent on a below-market tenant?
Only as the lease allows: at expiration, through scheduled increases, at a market-reset renewal or by agreement. Leases generally do not permit rent increases mid-term beyond stated escalations.
Should I pay a seller for projected rent increases?
Be careful. Value the property on in-place income and treat the upside as uncertain, because you carry the vacancy, cost and market risk of capturing it.
How do I find market rent for a commercial property?
Use recent comparable leases from CoStar or a broker's analysis, plus an appraisal if needed, and adjust for lease type, size, quality and location.
What are renewal options and why do they matter?
A renewal option lets a tenant extend the lease on stated terms. If the rent is fixed or capped, it can prevent you from raising rent to market for years.
