Interview 1: Sarah, LA ADU Landlord

“I spent $25,000 on a 40ft container ADU in my backyard and rented it to a young couple for $2,200/month. Net income was $21,000 in the first year, payback in 14 months. Now in year three, I‘ve made $60,000. Best investment I ever made.”

Interview 2: Mike, Texas Airbnb Entrepreneur

“I bought two 20ft containers on a vacant lot in Austin and turned them into separate Airbnb units. Each cost $18,000, daily rate $150, 75% occupancy. Combined net income for the first year was $50,000. I‘m planning to buy four more.”

Interview 3: John & Linda, Florida Retirees
