Weighted average lease term (WALT) is a portfolio risk metric that measures the average remaining time until lease expiration across a multi-tenant property or an entire portfolio. A property with a 7-year WALT has, on average, seven years of contracted rent remaining before the leases roll.
WALT is a single number that captures the near-term cash flow visibility of a property: high WALT means predictable income, low WALT means imminent leasing activity and the risks that come with it. Institutional investors, lenders, and asset managers all watch WALT as a core portfolio health indicator.
Two calculation methods are in common use. Rent-weighted WALT weights each lease's remaining term by the rent it generates, so large-rent tenants carry more weight in the average than small-rent tenants.
Area-weighted WALT weights by leased square footage, treating each square foot of occupied space equally regardless of rent. Rent-weighted WALT is more relevant for income stability analysis because it reflects the economic weight of each tenant; area-weighted WALT is simpler to calculate and provides a rough risk picture.
Sophisticated portfolio reports often show both, because the two can diverge meaningfully when a property has a mix of high-rent anchor tenants and lower-rent in-line tenants with different remaining terms.
Interpretation depends on strategy. Core institutional funds target long WALTs (often 7-10+ years) because the investment thesis rests on stable, bond-like cash flows and minimal near-term leasing risk.
Value-add funds typically operate with shorter WALTs (3-5 years) because their returns depend on resetting below-market leases at higher rents, which requires the existing leases to roll during the hold period. Opportunistic funds may deliberately seek properties with very short WALTs because those assets trade at a discount; the discount reflects the uncertainty, and the manager's edge comes from executing successful lease-up post-acquisition.
A property's WALT is not good or bad in isolation; it is good or bad relative to the strategy and the market.
WALT also affects financing. Lenders prefer longer WALTs because loan covenants tied to coverage ratios are less exposed to near-term cash flow disruption.
CMBS underwriting typically requires a specified minimum WALT at origination, and some loan structures include 'trigger' provisions that redirect cash flow to reserves if WALT falls below a threshold during the loan term. A property approaching loan maturity with a WALT shorter than the remaining loan term is a refinancing risk; the lender sees more leases expiring than principal being paid down, which signals potential income volatility right when the borrower is trying to refinance.
Sophisticated borrowers track WALT alongside refinance timing and structure hold-sell decisions partly around maintaining adequate WALT for their financing strategy.
WALT is a weighted average, not a simple one. Take each lease's remaining term, multiply it by that lease's weight, add the results, and divide by the total weight. The weight is what makes the number meaningful: weighting by contracted rent lets high-rent tenants count more, while weighting by leased area treats every occupied square foot the same.
The two methods answer different questions. Rent-weighted WALT is the better measure of income durability because it tracks where the money actually comes from; area-weighted WALT is easier to compute and gives a rough occupancy-risk picture. They can diverge sharply when a property mixes a large anchor paying below-average rent with smaller in-line tenants paying more, so institutional reports often show both.
A long WALT means most of the rent roll is contracted for years, so near-term cash flow is predictable and the property behaves more like a bond. That visibility lowers perceived risk, and buyers and lenders will often pay up for it, which shows up as a tighter cap rate on otherwise comparable assets. A short WALT means leases are rolling soon, bringing releasing costs, downtime, and uncertainty about where rents reset.
WALT also shapes financing. Lenders prefer a WALT that comfortably exceeds the loan term so coverage is not exposed to a wave of expiries mid-loan; CMBS deals commonly set a minimum WALT at origination and can trap cash if it falls below a threshold. A property nearing loan maturity with a WALT shorter than the remaining term is a refinancing risk, because more leases are expiring than principal is amortizing.
WALT is neither good nor bad on its own; it is read against the business plan. Core and core-plus mandates target long WALT (often 7 to 10 years or more) precisely because the thesis rests on stable, low-volatility income. A long WALT to strong-covenant tenants is exactly what a core buyer is paying for.
Value-add and opportunistic strategies often want the opposite. A shorter WALT (commonly in the 3 to 5 year range for value-add) is what lets a sponsor roll below-market leases to higher rents inside the hold period; opportunistic buyers may seek very short WALT deliberately, buying the vacancy and uncertainty at a discount and creating value by leasing the space up.
WALT (weighted average lease term) is the average remaining lease term across a multi-tenant property or portfolio, weighted by each tenant's contribution. It is a single number that captures near-term cash flow visibility: a high WALT means predictable contracted income, a low WALT means leasing risk is approaching.
Multiply each lease's remaining term by its weight (its share of total rent for rent-weighted WALT, or of total leased area for area-weighted WALT), add those weighted terms together, and divide by the total weight. The result is the average remaining term with larger tenants counting proportionally more.
Rent-weighted WALT weights each lease by the rent it produces, so it reflects income durability and is generally preferred for that. Area-weighted WALT weights by leased square footage, treating every square foot equally. The two can differ meaningfully when large tenants pay rents well above or below the building average.
Yes. WALT (weighted average lease term) and WALE (weighted average lease expiry) are two names for the same metric, the average remaining lease term across a property or portfolio weighted by rent or area. WALE is more common in some markets, WALT in others, but they measure the same thing.
A longer WALT locks in contracted income for more years, reducing near-term releasing risk and making the cash flow more bond-like. Buyers and lenders typically pay more for that certainty, and paying more for the same income is, by definition, a tighter cap rate. It is a common tendency rather than a fixed rule.
It depends on strategy, not an absolute target. Core investors want a long WALT (often 7 to 10 years or more) for stable, low-risk income, while value-add and opportunistic investors often prefer a shorter WALT (commonly 3 to 5 years or less) so leases roll and below-market rents can be reset during the hold.
