Discounted Cash Flow Valuation for Irish Commercial Property

TL;DR

Discounted Cash Flow (DCF) valuation projects an asset's annual cash flows over a hold period, discounts them to present value at a target return rate, adds a discounted terminal value, and produces a single present-value figure. It complements the simpler investment (capitalisation) method by capturing the time profile of cash flows — lease events, rent reviews, capex, vacancy. For Irish commercial assets with non-flat income profiles (reviewable leases, void periods, refurb plans, breaks), DCF is the institutional default. HPS Real Estate uses DCF alongside the comparable and investment methods on all material valuations.

When to use DCF

DCF is the right tool when the cash flow profile is not flat — which means most real-world Irish commercial assets. Specifically:

Multi-let assets with staggered lease expiries and rent reviews; assets with planned capex (refurb, repositioning, ESG upgrade); assets with known void periods or vacancy risk; development sites and assets in transition; mixed-use schemes with sector-specific yield differences; long-leasehold and income-strip transactions.

The DCF formula

Value = Sum over years 1 to N of (Cash Flow in year t / (1 + discount rate) to the power of t) + Terminal value at year N / (1 + discount rate) to the power of N.

Where:

Cash flow: the NOI in each year, reflecting contracted rent, expected reviews, voids and capex.

Discount rate: the target IRR for the investor at the relevant risk profile, typically 6 to 12 percent for Irish commercial in 2026.

Terminal value: the assumed sale value at year N, typically calculated by capitalising year N+1 NOI at an exit cap rate.

N: the hold period, conventionally 5 or 10 years for Irish commercial DCF.

Choosing the discount rate

The discount rate is the target unlevered IRR for an investor at the relevant risk profile. For 2026 Irish commercial DCFs HPS Real Estate uses indicative ranges of:

Core Dublin offices / prime logistics: 6.5 to 8 percent.

Core-plus secondary stock: 8 to 10 percent.

Value-add and repositioning plays: 11 to 14 percent.

Opportunistic / heavy value-add: 15 percent plus.

The discount rate should reflect risk, not financing structure. DCFs are typically run unlevered; leverage is layered in separately for investor reporting.

Choosing the terminal cap rate

Terminal cap rate is the exit yield assumed at the end of the hold. Common conventions:

Flat to entry: assume terminal equals entry yield (neutral assumption).

25 to 50 bps softer than entry: reflects depreciation, lease event wear, exit liquidity risk. This is the institutional default.

Sharper than entry: only justified by demonstrable repositioning (e.g. moving from Class B to Class A through capex programme).

Sense-checking a DCF output

Three sense-checks:

1. Compare to investment method. A DCF value materially above what the asset would trade for on a market cap rate suggests the inputs are too aggressive.

2. Stress-test the inputs. Run downside cases on rent growth, void length, capex overrun, terminal cap rate. The base case should fall within a credible range.

3. Reverse-engineer to assumptions. What rent growth and exit yield is the DCF actually pricing in? If those don't match the buyer's view of the market, the value isn't credible.

DCF limitations

DCF is sensitive to assumptions. Small changes in discount rate or terminal cap rate produce large changes in value. The discipline is in setting defensible inputs anchored in market evidence, not in the mechanical calculation. The Red Book requires valuers to disclose the key assumptions and to sense-check DCF outputs against the investment method.

Frequently asked questions

When should DCF be used to value Irish commercial property?

When the cash flow profile is not flat — multi-let assets, planned capex, void periods, lease event-heavy schedules, development transitions. For simple flat-income single-let assets, the investment method alone is usually sufficient.

What discount rate is appropriate for Irish commercial DCF?

2026 indicative ranges: core 6.5 to 8 percent, core-plus 8 to 10 percent, value-add 11 to 14 percent, opportunistic 15 percent plus. The right rate reflects the risk profile, not the financing structure.

How long should the hold period be in a DCF?Five or ten years is conventional in Irish commercial DCFs. Longer holds (15 to 25 years) are used for long-leasehold and ground-rent structures. The terminal value at the end of the hold typically does more work than the cash flows themselves.

What is the terminal cap rate?

The yield at which the asset is assumed to be sold at the end of the hold period. The institutional convention is to soften 25 to 50 bps from the entry cap rate to reflect lease-event wear and exit liquidity risk.

Is DCF used alongside the investment method?

Yes. Best practice on Irish commercial valuations is to run DCF alongside the investment method (comparable yield x NOI) and triangulate. If the two diverge materially, the valuer must understand and explain why before settling on the reported value.
