Personally, I agree with the majority here, that was one foolish mistake!
That home looks beautiful, and to think - it was completely 100% gifted to them, in addition to a large sum of money that would have paid the taxes on that home/property for the next quarter of a century!!! How many people seriously ever receive such blessings like that - they are few and far between!!
Sure sometimes you take risks in life, but that doesn't mean you gamble with everything you have! Ventures such as the one they attempted to take on should be thought out, and planned, and always always have budgets, marketing strategies, and flexible operation or you are just inviting failure!
What would have been smarter, would have been to start working that field in that area, work under another company that is already established, gain a feel for your market and potential success, then branch out to independent contracting with these already established businesses, working jobs for them, using their heavy machinery, and taking in flat fees - extra man-extra hands status.... THEN, if you were pulling good business as an independent, were building your reputation and establishing business colleagues with the surrounding big boys... Then you could start your venture, offering general labor, carpentry, etc. and later graduate to big-boy toys and full blown construction.
BUT thats what happens when you get greedy, see a large sum of money and think you can take on the world, and you are too hasty in your risk taking. Its just a shame really, because these people could have EASILY gotten by if they had been smart about it. But now, they are losing pretty much everything and their gorgeous family home.
I'm sorry, but when you get down to it, it was pretty idiotic of them to take a loan out on the FULL value of their home because that right there means they had NOTHING else left to save them should it have gone sour. And it did, and thus, they lost it all. No fall-back plan, no safety net set aside, nadda. Thats pretty foolish.
