Door Handles / Cabinet Hardware
There are many choices to consider when building/flipping SFRs (single-family residences). Personally, I prefer to spend a little more money and go with the Emtek brand for door handles. This is the same brand you'll find in multi-million dollar homes. Combine them with solid-core doors, and you're good to go!
