Until around 2007, McMansions mostly borrowed the forms of traditional architecture, producing vinyl Georgian estates and foam Mediterranean villas.

But in the last 10 years, this has begun to change: McMansions are now being constructed in architectural styles from the 20th century, specifically modernism. We are witnessing the birth and the proliferation of modernist McMansions: McModerns.

Though McModerns are commonly found in the places where modernism itself thrives—indoor-outdoor climates like the West Coast and the Southwest, and near liberal cities on the East Coast—they are also beginning to pop up in burgeoning tech hotbeds south of the Mason-Dixon, such as central North Carolina and Atlanta, Georgia. McModern houses are following the trail left behind by NPR, Chipotle, and MacBook Pros: They've become popular with younger, tech-savvier, and more highly educated individuals.

Shannon Affholter is the executive director of the Master Builders Association of King and Snohomish Counties, the largest and oldest local homebuilders association in the nation. Previously, he was the vice president of business and economic development for Economic Alliance Snohomish County. While there, he advanced strategic growth plans, advocated on behalf of business and fostered economic development in the region. He also was elected to serve two terms on the Everett City Council.

Prior to his tenure at Economic Alliance Snohomish County, Affholter was a business development executive at the regional accounting firm of Moss Adams and an account executive with Merck. He holds an MBA from Western Washington University and a Bachelor of Business Administration from Pacific Lutheran University. In The Money Hour segment today, Shannon talks about how the demand for housing has significantly outpaced residential housing supply.

Many businesses will benefit this year from the new 20 percent qualified business income deduction. This deduction applies to "pass-through entities:" partnerships, S-corporations, sole proprietorships, and most LLCs. However, if your taxable income from all sources exceeds $157,500 for an individual or $315,000 for a married couple filing jointly, your 20 percent deduction could be phased out. For these higher-income business owners, the deduction is limited to your share of your most advantageous calculation:

• 50 percent of the W-2 wages your company pays OR
• 2.5 percent of the purchase price of business fixed assets (with some limitations), plus 25 percent of W-2 wages paid.

The above assumes you are not a "Specified Service Trade or Business," but few construction-related companies are.

PRO TIP: If your company files a partnership return, beware the guaranteed income trap. Guaranteed income paid to the partners is not considered pass-through income eligible for the 20 percent deduction. Neither is the S-corp owner's W-2 pay, but at least that counts toward the 50 percent/25 percent W-2 wages in the above calculations, so it can help the owner qualify for the 20 percent deduction.

For more information, consult your CPA. There’s still time for last-minute tax strategies involving owner payroll, paying a spouse, or retroactive S-corp elections, among others.
