The main difference between a townhouse and an apartment lies in ownership and structure:

Townhouses:

• Ownership: You typically own the land your townhouse sits on, as well as the building itself. This means you have more control over the property and can make modifications as you please.
• Structure: A townhouse is a multi-story building that shares one or more walls with neighboring townhouses.
• Features: They usually have front and back yards or patio areas, a private entrance, and multiple floors. Some townhouses have basements or garages.
• Maintenance: You're responsible for the maintenance of the exterior of your townhouse, including landscaping, roofing, and siding. You may also have some responsibility for common areas.

Apartments:

• Ownership: While foreigners cannot own land in Indonesia, they can own strata title for apartments or units within a building. This means they own the unit itself and share ownership of common areas like the lobby, pool, and grounds..
• Structure: An apartment is a single unit within a larger building, often containing many units.
• Features: Apartments can come in various sizes and configurations. They typically have shared amenities like laundry facilities, parking lots, and sometimes swimming pools.
• Maintenance: The landlord is usually responsible for most maintenance and repairs, including the exterior and common areas.

Here's a simple table summarizing the differences:

In general, townhouses offer more privacy, ownership, and control over the property, while apartments offer lower costs, less maintenance responsibility, and more amenities.

Ultimately, the best choice for you depends on your individual needs and preferences.
