A South Florida developer is in the hot seat after an uptick in fraud among developers using government credits to fund low-income housing ventures grabbed prosecutors’ attention.

Pinnacle Housing Group Inc. affiliate DAXC LLC is accused of inflating construction costs to gain about $4.2 million from low-income apartment complexes in Miami, Sunrise, Homestead and Winter Haven. It paid $5.2 million, including forfeiture, and a $1 million fine to the federal government under a deferred prosecution agreement released Monday.
