(Bloomberg) — The number of wealthy people granted investor visas to live in the U.K. fell by more than 80 percent last year from the peak in 2014, a sign that luxury home sales in the capital may slump further.

While so-called Tier 1 investor visas rose 12 percent in 2016, the total granted was just 215, according to government data published on Thursday. That compares with 35,000 high-end properties planned for the city.

London’s luxury housing market has been beset by tax hikes, fears of oversupply and political uncertainty. Some developers hoped that the 16 percent fall in the pound since the referendum would help stabilize values in the capital’s best districts, which have fallen 12.5 percent from their 2014 peak as higher sale taxes and the Brexit vote damp demand, broker Savills Plc said in January.

“Weaker demand from Tier 1 Investors, uncertainty due to the vote to leave the EU, and stamp duty changes all mean the central London residential market continues to struggle,” Neal Hudson, founder of researcher Residential Analysts Ltd., said by e-mail.

Applications for the investor visas have slumped since the government doubled the minimum investment required for the permit to 2 million pounds and introduced new money laundering due diligence checks.

That’s hurt demand from overseas. The percentage of homes in central London’s best districts that were acquired by international buyers fell to 41 percent in the three months through December from 60 percent in the previous quarter, according to broker Hamptons International.

Successive increases in sales taxes are the main cause of falling home values in London’s most expensive areas, broker Knight Frank said earlier this month. The government brought in a 3 percent levy on second-home purchasers and landlords in April 2016, having earlier increased charges for all luxury-home buyers in December 2014.
