Home values in California could plunge by more than $56,000 and owners there could be exposed to $30,000 in new capital gains taxes under a House tax proposal that would cap the mortgage interest deduction at $500,000 and alter tenure requirements, new data indicates.

Home values in California could plunge by more than $56,000 and owners there could be exposed to $30,000 in new capital gains taxes under a House tax proposal that would cap the mortgage interest deduction at $500,000 and alter tenure requirements, new data indicates.

The brunt impact of the so-called “Tax Cuts and Jobs Act” on California home owners is  merely one of the alarming insights to emerge from a new state-by-state analysis by the National Association of Realtors (NAR) of the GOP tax bill that passed in the House on November 16.

“We know definitively that the tax reform proposals pending in Washington would hurt home values in every state across the country,” said NAR President Elizabeth Mendenhall in a statement emailed to Inman. She continued:

“And while some states would get hit harder than others, changes to the capital gains exclusion are among the many that could affect every homeowner regardless of their income or property value. There is real cause for concern that this kind of tax reform would harm homeownership, both for prospective buyers and for current owners. Realtors are doing their part to make sure lawmakers and homeowners have a clear understanding of what’s at stake.”

Owners in Connecticut, Massachusetts and Hawaii could all suffer significant home value declines of more than $40,000 under a House bill that would slash the mortgage interest deduction in half, from $1 million to $500,000, for newly purchased homes. A Senate bill expected to be voted on as early as Thursday evening currently preserves the current mortgage interest deduction for new homes at a cap of $1 million.

And because of provisions in both bills that would obligate owners to occupy a primary residence for five of the past eight years to qualify for tax exemptions, sellers in Colorado, Oregon and Washington could be exposed to nearly $20,000 in capital gains taxes. Currently, sellers aren’t responsible for taxes on the first $500,000 in profit from a sale, provided it’s a primary residence the owner has lived in for at least two of the past five years.

But the impact on Californians is the most severe, with approximately 6.9 million owner-occupied homes, nearly half valued at more than $500,000, effected by the new proposals. According to the NAR analysis, 4.3 million homeowners claimed a mortgage interest deduction and under the House bill many would be exposed to $28,875 in capital gains taxes. As for home values, many could see declines of up to $56,550, according to the NAR analysis.

A separate analysis by Zillow last week, meanwhile, suggested that Palo Alto and a host of other upscale towns in California, where median values clock in at approximately $2.5 million, would be faced with a whopping $97,200 in capital gains taxes upon selling with the first four years of ownership.

“Of the approximately 6,943,000 owner-occupied houses in California in 2016, 71 percent had a mortgage,” according to the authors of the NAR analysis, released on Wednesday. “49.1 percent of the housing units with a mortgage had a value higher than $500,000 while 9.0 percent of the owners paid over $10,000 for real estate taxes. Vacation homes accounted for 2.7 percent of the housing units in California.”

Chock-a-block with new data, the NAR analysis indicates that home values in Massachusetts could plummet by up to $49,450, or 14 percent, under the House tax proposal, while new tenure requirements in both bills could expose sellers to nearly $10,000 in new capital gains taxes.

In Connecticut, meanwhile, home values could fall by as much as $44,700 while sellers could be faced with a moderate increase of $240 in new capital gains taxes, owing to local tax regulations.

Colorado homeowners, too, could see values fall by as much as $36,000 while facing $19,125 in new capital gains taxes if they choose to sell within four years of purchasing their home.
