I enjoyed reading the updates DM, lot of fun, almost felt like I was in your driveway myself there a few times lol.
Certainly sounds like it was a very positive experience all round for bith you, and your wifes hair lol.
No doubt you will be out on the trail of some other units soon, so looking forward to hearing more as it all unfolds.
I'm sure others that are reading your updates would also be considering this as a potential supply resource now, and why wouldn't they. Only thing is of course that everyone just needs top keep it all in perspective.
My understanding is that in the majority of cases you have to bid blind (bid without actually knowing what's in side), so it is a gamble. While there is golden opportunities there as you have found out, there are going to be money pits where you end up with ZIP!
Perhaps treating the resource as a long term investment would be the best way to approach it. Take the good with the bad and then see if you come out in front in 6 months time or something. I think it's a little like dealing in the surplus market. Go into that market expecting to make money straight off the bat and you can loose out big time.
Of course if someone can find a place that lists what is in the units before the bidding takes place, then that takes most of the risk out of any purchase, of course it will also most likely increase the amount you pay for it : )
