The Corner Lot With Two Possible Lives
Subject is a 0.32-acre corner lot zoned R-2, which permits duplexes. It is improved with a 1,150-square-foot 1952 cottage that is legally conforming. The neighborhood is transitioning toward duplexes. The cottage's value as is is $285,000, of which land is $120,000 and improvements are $165,000. Vacant lot value as a duplex site is $145,000. A new duplex would cost $380,000; a completed duplex would sell for $495,000; entrepreneurial incentive is 10% of construction cost. Demolition would cost $18,000. The cottage rents for $1,450 per month; a new duplex would rent for about $2,300 total. The owner asks whether to demolish and build a duplex.
1. Test the duplex development for financial feasibility.
Read the worked answer
Total duplex development cost includes land, construction, and entrepreneurial incentive. Land is $145,000; construction is $380,000; incentive at 10% of construction is $38,000. Total cost before demolition is $563,000. Because the site is improved, demolition of $18,000 must be added, producing about $581,000. Completed duplex value is $495,000. The indicated loss is about $86,000. Even if the owner already owns the land and ignores its opportunity cost, the construction plus incentive plus demolition is $436,000, still below $495,000 but leaving only about $59,000 for land, well under the $145,000 site value. On a full-cost basis, the duplex is not financially feasible at current costs and values.
2. What is the highest and best use as improved, and as vacant?
Read the worked answer
As vacant, a duplex is legally permissible, physically possible, and consistent with the neighborhood transition, but it fails the financial feasibility test by about $86,000. Therefore, duplex development is not the highest and best use as vacant at current prices. As improved, the cottage is legally conforming and contributes $165,000 above the land value; its continued residential use is financially feasible and produces rental income. The existing use is worth more than the vacant duplex site ($285,000 versus $145,000). The highest and best use as improved is continued single-family residential use, possibly as an interim holding use until duplex economics improve. Demolition is not justified now.
3. How should the owner's question be answered, and what value implications follow?
Read the worked answer
I would tell the owner that the market does not currently support demolition and duplex construction. The as-is value should reflect the cottage's continued use, not a duplex hypothetical. A subject-to-completion duplex value would require a hypothetical condition and would not be the as-is market value. The owner could hold the property, collect rent, and monitor duplex rents and construction costs for a future feasibility threshold. If construction costs fell or duplex values rose enough to close the roughly $86,000 gap, the analysis could change. The appraisal should disclose the HBU conclusion, the feasibility calculation, and the fact that the existing improvements contribute value above the land.
