When using the word 'renmen,' how do you distinguish between love and like? Is there a better way to make this distinction?

The answer is, you don't.  Renmen translates both love and like
You can say:
Mwen renmen'w amò.
I love you to death.
or
Mwen renmen jan kay sa bati a.
I like the way this house is built.
