Stacking the stack: one building, four credits

The most valuable real estate credit work is rarely a single program. Picture a vacant 1920s school building in a designated community. Certified as historic, its restoration earns the 20 percent federal rehabilitation credit and a state historic credit on top. Converted into affordable apartments, it draws a 4 percent LIHTC allocation paired with tax-exempt bonds. Efficient design across the forty units triggers the energy efficient home credit, and a rooftop solar array placed in service at completion adds an investment credit with a bonus for siting. Each program has its own eligible-cost definition, and the same dollar generally cannot count twice, so the work is in carving the budget so each credit draws from the costs that serve it best. Then the limitation rules take over: the developer cannot use most of this personally, so the housing credits are syndicated to an institutional partner, the state historic credit is sold for cash at a discount, and the energy credits are transferred. What starts as a pile of incentives becomes a capital stack — and the difference between a project that pencils and a building that stays empty is almost always the quality of that carving, done at design, not at tax time.
