Spatial Joining Polygons to Raster Cells

I am trying to create a raster surface showing the amount of housing units within a quarter mile from raster cells with a cell width of 50 feet. To do this I need to be able to somehow spatially join the tax parcels (polygons) within 1320 feet of the cell to the cell in order to get the total number of housing units within a quarter mile of each cell.

I have currently accomplished this task by using the label points from a fishnet as sample points, then spatial joining all parcels to the points that intersect a 1320 foot buffer around the points. I then take these points and create a 50 foot resolution raster surface using IDW. The problem is that it requires me to create over 13 million points!

Is there not a faster way?
