Land Buy-Back Program Valuation Division

The Cobell Settlement Agreement

The Land Buy-Back Program for Tribal Nations (LBBP) was established by the Secretary of the Interior on December 17, 2012, to implement the land consolidation provisions of the Cobell Settlement Agreement. The Cobell Settlement provided a $1.9 billion trust land consolidation fund to consolidate fractional land interests across Indian Country by purchasing fractional interests in trust or restricted-fee land from willing sellers at fair market value within a 10-year period, which ends November 24, 2022. AVSO's Land Buy-Back Program Valuation Division (LBBPVD) supports LBBP by determining market value of the land. Appraisal reports providing fair market value are the primary foundation for individual offer amounts as required by the Cobell Settlement. Thus far, the LBBP has conducted either mass appraisals or site-specific appraisals in more than 55 locations in Indian Country:

AVSO's LBBPVD will be closing on March 31, 2022, due to limited remaining funds and the time needed for trust and restricted-fee land purchases by LBBP.

Mass Appraisal

Mass appraisal is the process of valuing a group of properties as of a given date using common data, standardized methods, and statistical testing. The LBBPVD uses mass appraisal methodology to significantly reduce the time and cost of producing high-quality appraisals. A mass appraisal is basically a market study analysis using multiple regression (statistical testing), following USPAP and IAAO standards.
