how to get involved with Habitat for Humanity?

You will need a few thousand dollars - you have to pay for your travel, your accommodations, and fees that cover the staff time to supervise you, create things for you to do that don't take away local jobs, etc.

The Habitat For Humanity web site provides more details.

Labor and construction materials can be cheap, depending on the country. How much money are you going to need in order to go to these destinations ... it all depends. Are you willing to help farmers who are so poor that their roof is falling off? Helping them is wise since they have the means to support themselves. A farmer's house can cost $6,000. It all depends on the country. You can make the same house for $1,500 in the middle of a jungle, but try to remember that people in the country are always comparing what they have to those in the city.

This website should help :)
