What an assessor needs to observe
Fieldwork establishes the condition and quantities behind the forecast. Site improvements, envelope, roofs, mechanical systems, interiors, and unit components need a representative record. Review completed replacements and proposed rehabilitation separately; a system’s calendar age alone does not establish its remaining life.
USDA Rural Development CNA
USDA uses a CNA process addendum, statement of work, review process, and repair/replacement schedule. For transfers, rehabilitation and the subsequent 20-year reserve analysis need to be coordinated. Confirm the current RD-approved scope and inspection sample. The loan servicer’s transfer inspection is a separate step—not the consultant’s sampling requirement.
HUD CNA e-Tool
The e-Tool standardizes assessment data, submission, review, and approval across multiple HUD programs. The applicable program and MAP guidance establish the technical requirements. A useful submission needs consistent component inventories, alternatives, repair costs, replacement timing, financial assumptions, and supporting documents; uploading a narrative PDF alone does not complete that workflow.
Inspection samples are materially different
RD’s published CNA Addendum, Attachment B, specifies at least 50% of dwelling units for properties below 50 units, 45% for 50–99 units, and 40% for 100 or more units, with representative distribution. HUD MAP Appendix A.5.7 specifies, for the listed existing-property programs, at least 10% for properties built and occupied as new construction within ten years of the CNA and at least 25% for others. Vacancy patterns and adverse conditions can require expanded observation. Verify current program instructions and any applicable modifications before setting the access plan.
Avoid double counting rehabilitation and reserves
Identify which components will be replaced using the rehabilitation budget, then reflect their post-rehabilitation condition in the future forecast. Show any later replacement falling within the analysis period. Keep routine operating expenses distinct from capital items and make inflation and cost-date assumptions visible.
