A well-designed property with a functional layout tends to be more marketable. Whether you're renting it out or selling it, a property that appeals to the majority of potential renters or buyers will command a better price and will be easier to move on the market.

Efficient use of space can lead to increased renter or buyer appeal. It can also allow for more usable living spaces, potentially making the property suitable for a broader range of potential occupants.

 A well-designed home can be easier and cheaper to maintain. Think about roof designs that prevent water pooling or layouts that allow for easy access to utilities.

Homes designed with natural light, airflow, and insulation in mind can be more energy-efficient. This can be a selling point for environmentally-conscious renters or buyers, and it can also mean reduced utility costs, a significant consideration for long-term renters.

Depending on the location and intended rental market (families, singles, students, etc.), different layouts and designs will be preferable. For example, open-plan designs might appeal to modern renters, while a property in a family-oriented neighborhood might benefit from having multiple bedrooms and child-friendly features.

Even if you're looking to hold the property long-term, it's essential to consider the eventual resale value. A home with a timeless design and flexible layout is likely to hold its value better than one with a niche or outdated design.
