Valuing a Retail Property Investment

As a senior analyst in a real estate investment firm, you are tasked with determining the appropriate valuation method for a freestanding retail property that spans 15,000 square feet in a high-demand area. The property is currently leased to a reliable tenant with a long-term lease that features a fixed rental rate but lacks escalation clauses. Given the details of the property and tenant stability, you must decide among three common valuation methods:

(1) Discounted Cash Flow (DCF) Approach

(2) Comparable Sales Approach

(3) Capitalization Rate Approach

The market conditions show a trend of increasing demand but also a rise in capitalization rates due to potential interest rate hikes. Given these circumstances, which valuation method would be the most accurate for this type of property investment?
