Republican presidential candidate Donald Trump uses a chart to illustrate what he said was the drop in U.S. home ownership under President Barack Obama during an address to the National Association of Home Builders' board of directors Thursday.

Republican presidential candidate Donald Trump emphasized his family connections to the homebuilding industry in a speech to the National Association of Home Builders' board of directors Thursday, talking about how his father—a real estate developer—was a huge influence on his life.

"I learned so much from a homebuilder," Trump told board members, who were gathered in Miami Beach, Fla., for a meeting. "There's no greater thing you can do."

Trump's speech to the NAHB board was streamed online by the association. The candidate, known for his controversial remarks, one point repeated his claim from the previous day that President Barack Obama was the "founder of ISIS." He labeled his Democratic challenger Hillary Clinton the MVP (most valuable player) of the terrorist organization.

Mostly, however, Trump stuck to economic and tax issues, receiving applause for pledges to reduce taxes and regulations on the homebuilding industry. The association's board has more than 2,000 members.

Claiming that 25 percent of the cost of a new home is the result of government regulation, Trump said he would like to see that figure reduced to 2 percent. He said that as president he would reduce the taxes small businesses pay to no more than 15 percent, make child care costs tax deductible, eliminate the carried interest deduction, end corporate tax inversions, and get rid of the estate tax.

In addition, he dinged Clinton and the current administration for their handling of foreign policy and entering into trade deals the candidate believes has harmed the U.S. economy.

"We have incompetent leadership and this is not what we want, and it will change if I am elected president, believe me," Trump said.

Trump also showed a more personal side, opening his speech about father Fred Trump, a real estate developer who built the family fortune. The candidate spoke about the values his father imparted to him and how those values were reflected in the homebuilding industry.

"I know where you come from. I know your mindset. You are doing amazing things," Trump said.

NAHB does not endorse presidential candidates. In a statement issued in February, the association said its government affairs staff planned to meet with the policy teams of all the presidential candidates to discuss issues important to the industry.
