Rosa Garcia, a real estate agent, eagerly greeted a young woman and her family when they showed up on Saturday at 1 p.m. for an open house in Pasadena, Calif.

Ms. Garcia, 50, who has been working in real estate for 24 years, has a personal interest in the three-bedroom home listed for $2.175 million. Her nephew bought it last year as an investment, and she lent him money to renovate the kitchen and two-and-a-half bathrooms.

When they were making plans to flip the home, they could not predict the catastrophic fires that have engulfed Los Angeles, threatening their property and upending the real estate market. Pasadena neighbors Altadena, a community where at least 16 people were killed and more than 7,000 structures have been destroyed by the Eaton fire. But Pasadena, a picturesque city at the foot of the San Gabriel mountains, escaped the fires largely unscathed.

So as Lisa Chen and her toddler walked around the home on Saturday, Ms. Garcia was sure to note that the white stucco house high up in the hills overlooking a steep canyon had a new, fireproof roof and had fared well in the fire.

Ms. Chen, 32, a stay-at-home parent, told a reporter that she has been house hunting for a year. Before the fires, she had prioritized living in a neighborhood with good schools. Safety is now also at the top of her list, she said, and living in the hills is dicey. “The flats are better,” she said as she left.
