I thought they were a high initiation fee scammer outfit.My best sources have been the ReHab stores of Habitat For Humanity, yard sales (particularly higher end subdivisions) and close out sales.

I recently signed up to a free DIY course at a local Home Depot and have participated in a couple Habitat for Humanity homes (mostly caulking and painting).Does anyone know of other methods to get experience in remodeling and rehabbing homes?

Are door knobs the type of the thing that Habitat for Humanity stores would stock?  

Network, volunteer in real estate and community groups (like habitat for humanity or neighborhood redevelopment groups), always keep an eye out for opportunities.

In my area habitat for humanity gets more items donated that they can use use.

There are organizations that have this niche, Habitat For Humanity for example but they can't use government funding and others move in where they leave off.

go to Habitat for Humanity's Rehome store.

@Dannielle HoffmanThe Habitat ReStore has pretty decent quality cabinets at a great price.  

I  like Habitat for Humanity and jimmy-rigging.

Habitat for Humanity has a surplus store on Beach Blvd near University Blvd.
