Real assets face six main risks: vacancy, construction delays, interest rates, refinancing, obsolescence and regulation. Borrowed money magnifies all of them. The risks tend to arrive together: a rate rise can hit values and refinancing at the same moment. So they must be stress-tested together, not one at a time.
Why it matters: A plan that survives each risk alone can still fail when they hit together.
Summary: Real assets carry vacancy, construction, interest-rate, refinancing, obsolescence and regulatory risks, all magnified by leverage. The risks arrive together, so they must be stress-tested together, not one at a time.
- A 10% NOI fall alone cuts value 10%; a cap rate rise from 6.5% to 7.5% alone cuts it 13.3%.
- Together they cut value 22.0% and equity 63% for a building with an $80.0M loan.
- Long net leases to strong tenants behave like corporate bonds; development projects need a DCF, not a cap rate.
- A practical stress set: NOI −10%, cap rate +1 point, refinancing 2 points higher, then all three at once.
Beyond the general market and credit risks covered in Capital Markets, real estate and infrastructure carry several asset-specific risks, which come from owning one long-lived, immovable, usually leveraged asset.
| Risk | What It Means |
|---|---|
| Vacancy Risk | The risk that a property cannot find tenants at the assumed rental rate, directly reducing NOI and, through the cap rate formula, the property’s value |
| Construction/Completion Risk | The risk that a project is delayed, exceeds budget, or fails to be built to specification — most acute during an infrastructure project’s build phase, before any revenue-generating operations even begin |
| Interest Rate Risk | As shown in Section 2.2: Cap Rates and Property Valuation, real estate values are sensitive to interest rate movements through the cap rate mechanism, in addition to the direct effect on financing costs |
| Regulatory/Political Risk | Particularly relevant for PPP and infrastructure investments, where a change in government policy, tariff regulation, or contract renegotiation can materially affect long-dated project economics |
| Refinancing Risk | A maturing loan cannot be replaced at the same amount because rates, cap rates or lending standards have moved, forcing new equity or a sale even when the building is full (Section 2.4: Commercial Real Estate Debt — Mortgages, CMBS, and Mezzanine) |
| Obsolescence Risk | Tenant demand moves away from a building type or location, lowering expected NOI growth and raising the capital spending needed to compete, so the cap rate rises even if interest rates do not |
This Part’s cap-rate and DSCR tools assume a stabilized asset with market leases and fixed-rate debt. These situations change the answer.
| Situation | What changes | Why |
|---|---|---|
| Long net lease to an investment-grade tenant | Value it like a corporate bond; the cap rate tracks the tenant’s credit spread | NOI is fixed by contract, so g is near zero and the cap rate is close to r |
| Development or lease-up | Cap rate and DSCR on current NOI are meaningless; use a DCF and loan-to-cost | There is no stabilized NOI yet |
| Floating-rate loan with a purchased rate cap | Unhedged rate rises hit DSCR at once; the cap’s expiry is a cliff | Debt service resets with the benchmark rate |
| Availability-payment PPP | Traffic risk disappears; government credit and performance deductions replace it | Revenue comes from a budget, not users (Section 2.7: Public-Private Partnerships (PPPs)) |
| Regulated utility | The allowed return and the next rate case dominate | Revenue = r × RB + E + D + T (Section 2.6: Infrastructure Debt and Equity — Who Invests and Why) |
| Building with structural vacancy | The cap rate can rise while interest rates fall | Lower g and higher capital spending raise r − g |
These risks are correlated: a recession raises vacancy while lenders tighten, and a rate shock lifts cap rates and refinancing costs together. That is why the stress test below runs the shocks at the same time.
Run three shocks before committing to a real asset: NOI −10%, cap rate +1 point, and refinancing 2 points higher, then all three together. If the combined case leaves DSCR below 1.0× or wipes out more than half the equity, cut leverage or walk away. These thresholds are heuristics. For contracted assets, replace the NOI shock with a counterparty default or a contract renewal at lower prices.
Stress-testing risks one at a time. For the $8.00M-NOI building with an $80.0M loan, a 10% NOI fall alone cuts value 10%, and a cap-rate rise from 6.5% to 7.5% alone cuts it 13.3%. Together, as when a recession follows rate hikes, value = $7.20M ÷ 0.075 = $96.0M, down 22.0%, and equity falls from $43.1M to $16.0M, a 63% loss.
What are the main risks of investing in commercial real estate?
Vacancy, interest rates (higher cap rates), refinancing (a maturing loan replaced by a smaller one), obsolescence (tenants leaving a building type) and illiquidity (slow, discounted sales). Leverage magnifies all of them: in the worked example a 22% fall in value costs equity 63%.
Is infrastructure less risky than real estate?
Contracted and regulated infrastructure often has steadier cash flow, because long contracts or regulators set revenue rather than leasing markets. Its risks differ: construction, regulatory resets, political renegotiation and, for demand-risk assets, usage. Greenfield or market-price infrastructure can be riskier than a leased office building.
How does inflation affect real estate values?
Through both parts of cap rate = r − g. Inflation usually lifts interest rates, raising r and lowering values, but it can also lift rent growth (g) where leases reset or are indexed. Short leases and indexed contracts pass inflation through; long fixed-rent leases behave more like bonds.
Cap rates in rupees. An office building with ₹8 crore of NOI at an illustrative 6.5% cap rate is worth ₹8 crore ÷ 0.065 ≈ ₹123 crore; at 5.5%, ≈ ₹145 crore (Section 2.2: Cap Rates and Property Valuation).
REITs and InvITs. Under SEBI‘s 2014 regulations, at least 80% of a REIT’s assets must be completed, revenue-generating property, and REITs and InvITs (infrastructure investment trusts) must distribute at least 90% of net distributable cash flows at least half-yearly: India tests distributable cash where the US tests taxable income (Section 2.3: REITs — Real Estate as a Public Market Asset). REIT borrowing is capped at 49% of asset value. InvITs may borrow up to 70%, net of cash, if they hold an AAA rating, have made six continuous distributions and obtain unitholder approval; since May 2026, borrowing above 49% may fund capital spending, major road maintenance and refinancing of principal, not only acquisitions. Small and medium REITs (schemes of ₹50 crore to under ₹500 crore) followed on March 8, 2024, and from January 1, 2026, mutual funds treat REITs as equity while InvITs remain hybrid.
Hybrid Annuity Model (HAM). On national highways, the authority pays 40% of the bid project cost during construction, in five equal installments linked to physical progress, and the remaining 60% in semi-annual annuities after completion, with interest on the reducing balance at a benchmark lending rate plus a spread fixed in the concession agreement (the bank rate plus 3 points in the original model agreement). The authority collects the tolls, so traffic risk stays public: an availability-style structure (Section 2.7: Public-Private Partnerships (PPPs)).
Viability gap funding (VGF). Where user charges cannot repay a project, the central government and the sponsoring authority may each grant up to 20% of total project cost; social-sector projects (water, waste, health, education) up to 30% each, and pilot health and education projects up to 40% each (guidelines of December 7, 2020).
National Monetisation Pipeline. The government leases income rights in operating assets, often through InvITs, and recycles the proceeds into new building. The finance minister reported about 90% of the first ₹6 lakh crore four-year target achieved; NMP 2.0, launched in February 2026, targets ₹16.72 lakh crore over FY2025-26 to FY2029-30.
Real assets face vacancy, construction, interest-rate, refinancing, obsolescence and regulatory risks, magnified by leverage and correlated in downturns. Stress-test them together: in the worked example a 10% NOI fall and a one-point cap rate rise together cut value 22.0% and equity 63%.
Six questions on this chapter. Decide on your answer first, then click “Reveal Answer.”
1. A building has $10M of NOI, a 6.0% cap rate and a $100M loan. NOI falls 10% and the cap rate rises to 7.0% at the same time. Roughly how much of the equity is lost?
- About 36%
- About 57%
- About 10%
- About 23%
Reveal Answer
Answer: B. Value falls from $10M ÷ 0.06 = $166.7M to $9M ÷ 0.07 = $128.6M, so equity falls from $66.7M to $28.6M, a 57% loss.
2. What is refinancing risk in real estate?
- A major tenant leaves well before its lease expires
- A builder fails to finish the project on time
- A maturing loan can be replaced only by a smaller one
- A regulator cuts the allowed return at a rate case
Reveal Answer
Answer: C. If rates, cap rates or lending standards have moved, the new loan may be smaller than the balance due, forcing new equity or a sale.
3. Tenant demand moves away from a building type while interest rates stay flat. Why can the cap rate still rise?
- Expected NOI growth falls and capital needs rise
- Lower tenant demand lowers the required return r
- The loan constant on the existing debt rises
- Vacancy is excluded from NOI by market convention
Reveal Answer
Answer: A. Obsolescence lowers g and raises the spending needed to compete, so the cap rate rises even with unchanged rates.
4. A building is leased for 20 years to an investment-grade tenant at fixed rent. How should you value it?
- Like a development site, sized on loan-to-cost
- Like a hotel, priced on nightly room revenue
- Like a utility, earning an allowed return on rate base
- Like a corporate bond priced on the tenant’s credit
Reveal Answer
Answer: D. Contracted NOI makes growth near zero, so the cap rate is close to r and moves with the tenant’s credit spread.
5. Worked problem: A building worth $120m has a $70m loan. NOI falls 10% and the cap rate rises from 6.5% to 7.5%. What is the new value?
Reveal Answer
Answer: Value = $120m × 0.90 × (6.5 ÷ 7.5) = $93.6m, a fall of 22.0%.
6. Worked problem: What happens to the owner’s equity?
Reveal Answer
Answer: Equity falls from $50m to $93.6m − $70m = $23.6m, a loss of 53%: leverage magnifies the combined shock.
