Housing growth in Tennessee that incorporates spatial spillover and spatial heterogeneity at the level of census-block group is projected. A deterministic interpolation technique is adopted to create alternative neighborhood variables that captures spatial spillover of neighborhood effects on housing growth without multicollinearity. The maps drawn using the geographically weighted regression parameter estimates revealed that the local marginal effect of the housing price increases on housing growth gradually increases as one moves eastward. The population growth in the adjacent neighborhood-block group has about 10% of marginal effect of population growth in its own block group. The marginal effect of population growth is relatively higher in the approximate area of Cumberland Plateau while the local marginal effect of spatial spillover of population growth in adjacent neighbor is relatively higher in the East Tennessee and also the area South of Nashville.
