The property at 15 Valley Rd, Southborough, MA, with its 3,150 sq ft and four bedrooms, has a considerable rent potential ranging from $4,700 to $7,000 monthly. This range is derived from comparable properties in the area. The payback period, given these rents, would be relatively short, enhancing the investment's attractiveness. Southborough is experiencing favorable market conditions with stable demand and increasing property values. The colonial style, central air, and finished basement are significant features that enhance its rental appeal. However, being a single-family home, it may attract a less diverse tenant pool.

To further increase rental income potential, consider modernizing the kitchen and bathrooms, enhancing energy efficiency, and adding smart home features. If considering selling, emphasize the property's proximity to major routes and top-rated schools, which are significant selling points. Invest in minor landscaping to improve curb appeal, which can boost both rental and sale value.
