The "Property Ladder" refers to the process of buying and selling properties to move up to larger or more valuable homes over time. Individuals typically start with a smaller, more affordable property, often a starter home, and then sell it to purchase a bigger or better one as their financial situation improves. This concept is common in real estate markets, where homeowners aim to build equity and increase their investment. The idea is that by climbing the property ladder, individuals can eventually own their dream home or a more desirable property in a better location.
