What Is Below-Market Rent?
Below-market rent = current rent < market-rent. A unit renting for $1,150 when rental-comps support $1,325 has $175/month below-market-rent upside. Underwrite at market-rent, not current rent—that's your stabilized noi. The gap is opportunity. Common causes: long-term tenants, deferred increases, poor management. In Kansas City, an investor bought a 4-plex with units at $950–$1,050; market-rent was $1,200. He raised at turnover. Effective-gross-income jumped 15% in 18 months.
Below-market rent means the current rent is less than what the unit would fetch in the open market based on rental-comps. It's a value-add opportunity—you can raise rent at turnover or renewal.
At a Glance
- What it is: Current rent below market-rent
- Why it matters: Value-add upside; higher noi at stabilization
- Source: Rental-comps vs. actual rent
- Use it for: Deal-analysis; underwriting
- Risk: Turnover to capture; tenant pushback
How It Works
Finding it. Run rental-comps—similar units, similar location. Compare to current rent. If current < comps, you have below-market-rent.
Why it happens. Long-term tenants who haven't had increases. Landlord who didn't keep up with market. Deferred maintenance that justified lower rent. Rent control in some markets. Inherited leases from a prior owner.
Underwriting. Use market-rent for noi and deal-analysis. Don't use current rent—that understates the property's potential. The upside is the spread: market-rent − current rent. You capture it at turnover or renewal.
Timing. You may not get it day one. Staggered leases mean staggered increases. Model a ramp: Year 1 at blended rent, Year 2–3 at full market-rent. Or assume immediate turnover—conservative on timing, aggressive on rent.
Real-World Example
Ava in Memphis. She looked at a 3-bed duplex. Unit A: $1,100. Unit B: $1,150. Rental-comps for similar 3-beds: $1,275–$1,350. Market-rent: $1,325. Current gross: $2,250. Market-rent gross: $2,650. $400/month upside. She underwrote at $2,650. NOI at market-rent: $1,590. At current rent: $1,350. The $240 NOI gap justified a higher offer. She closed, raised Unit A at renewal (6 months), Unit B at turnover (4 months). Hit market-rent in 10 months.
Pros & Cons
- Built-in upside
- Supports higher noi underwriting
- Common in neglected portfolios
- Requires turnover or renewal to capture
- Tenant pushback possible
- Don't overstate—use supported market-rent
Watch Out
- Rent control: Some markets limit increases—check local rules
- Lease terms: Long-term leases delay capture; factor that in
- Conservative comps: Use market-rent from solid rental-comps, not aspirational numbers

The Takeaway
