Allison Brown and her husband lived in a 1,500-sq-ft trailer in South Dakota to save money. They used savings to build a 3,600-sq-ft home for $410,000 by managing the project themselves. They converted the old trailer into an Airbnb for additional income. Their strategy highlights cost-effective housing and entrepreneurial living.
