Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes During the three months ended June 30, 2020 and 2019, the Company recorded a tax provision of $17.2 million and $11.0 million, respectively, which reflects income tax expense related to the periods’ income before income taxes. The effective tax rate for the three months ended June 30, 2020 and 2019 was 24.0% and 26.6%, respectively. During the three months ended June 30, 2020, we recorded a $0.8 million tax benefit related to the retroactive reinstatement of energy efficient homes tax credits. During the six months ended June 30, 2020 and 2019, the Company recorded a tax provision of $26.8 million and $16.7 million, respectively. The effective tax rate for the six months ended June 30, 2020 and 2019 was 23.7% and 25.8%, respectively. During the six months ended June 30, 2020, we recorded a $1.2 million tax benefit related to the retroactive reinstatement of energy efficient homes tax credits and a $0.4 million increase in tax benefit from equity compensation taken during the first half of 2020. The Company had $0.3 million of state net operating loss (“NOL”) carryforwards, net of the federal benefit, at June 30, 2020. Our state NOLs may be carried forward from one to 15 years, depending on the tax jurisdiction, with $0.2 million expiring between 2022 and 2027 and $0.1 million expiring between 2028 and 2032, absent sufficient state taxable income. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was signed into law. The CARES Act includes several significant business tax provisions including modifications for net operating losses, credit for prior-year minimum tax liability and limitations on business interest and charitable contributions. The CARES Act also provides for an employee retention credit and technical corrections regarding qualified improvement property. We are assessing the tax impact of the CARES Act as it relates to the Company.
