If you think that the land will be more valuable in a few decades, that is an argument for wanting to own it. If your solar adventures can pay for just the interest on what you bought the land for, then you have the upside of land speculation without the downside.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
