Just seven months after Barry Brandon Bordelon and Jordan Noah Slocum met, they put their entire savings together and bought a 19th-century Brooklyn brownstone, Mr. Slocum said. That home, in Bedford Stuyvesant, changed their lives.

“From that purchase, we started our business together,” Mr. Slocum said. That was seven years ago. The two, now known as the Brownstone Boys, have since renovated more than 27 prewar homes together.

The two first connected on April 4, 2017 on Grindr, but it was a week and a half before they met in person. “We talk about how weird it is because that’s not what usually happens on Grindr,” Mr. Slocum said of their virtual correspondence. “We talked nonstop.”

For their first date, they chose the Crown Inn, a bar in Crown Heights, Brooklyn, a favorite within walking distance for both.

“We talked for hours and hours,” Mr. Bordelon said, until 1 or 2 in the morning. “Which is rare for me because I’m in bed by 9 or 10,” Mr. Slocum said. It was worth staying up for. “We ended the night with a passionate kiss,” Mr. Slocum said.

Their second date was the following weekend. “We had a very low-key date at Jordan’s house, just ordering food and watching TV,” Mr. Bordelon said.
