The National Housing Conference and Center for Housing Policy have created a suite of new materials exploring lifecycle underwriting, a new way of thinking about the costs of affordable multifamily rental housing. The materials include a Lifecycle Cost Modeling Tool to help developers estimate whether a property is likely to fund its long-term capital needs, such as a new roof or HVAC system, over time. There are also working papers on comparing the cost of new construction and acquisition-rehab, potential policy implications of lifecycle underwriting, and the methodology behind lifecycle cost adjustment.
