Thanks blue31. That's true. Because those modified houses meet

people's needs. And the modification was based on their interest.

That's why the modified houses can be rented higher.
For them, the capacity is more important than the quality, because that's their immediate needs.

We need to think about people, concern about people and serve people. :)

Can anyone share how easy or difficult to get permit for an already modified house? Do we need to open everything for inspection etc? That would be costly.

Thank you, blue31.
