I've thought about that approach.  I think if you do that, it becomes more of a long-term missions arrangement where you have a smaller team maintaining a longer-term presences down there.  It could probably make an even bigger impact, but it wouldn't be as accessible to the folks back home.  (It's easier for a teenager to go build houses for a week than for them to learn enough Spanish to provide training and education)

Interesting perspective. Do you think partnering with and funding local builders while having volunteers focus more on training, education, or community support could create an even better long-term impact? Curious to hear your thoughts.
