For 37 Hastings Rd, Belmont—a 4-bed, 2.5-bath single family home (2066 sqft)—the estimated monthly rent potential sits in the $4.2K–$6K range, anchored by comp data from similar nearby properties. Average rents for large homes in Belmont are notably high, with recent 3–4 bed listings in the $4K–$5K+ zone. At $4.2K/month, annual gross revenue would be around $50K; at $6K, about $72K. The payback period, absent mortgage, would be roughly 24–34 years (using the $1.73M valuation). Demand for spacious, well-located homes remains strong, especially with excellent school ratings and proximity to Belmont Center. The Colonial architecture, spacious lot, and updated heating add rental appeal, though the lack of central cooling and a garage could be minor drawbacks. Overall, this block commands a premium for family renters seeking top-tier schools and suburban living.

To maximize rental value, consider adding central air, updating baths or kitchen, and highlighting school proximity in marketing. If selling, timing with the spring market or after minor upgrades could boost returns—Belmont's tight housing supply and high rent trends make this a prime candidate for both leasing and sale. Owners should weigh a light renovation against current demand: even modest improvements could push rent toward the higher end of the range.
