If the Casa Lago doesn't need any repairs (other than a coat of paint) it sounds like the better option, even though it is smaller than the Camino Viejo. The other one would depend on the kind of repair work it needs. I assume that those kind of projects tend to turn out more expensive than initially estimated, so maybe it's best not to drain your liquidity right away. Talking about liquidity, having to pay everything up front in cash would be a deterring factor anyway, even if crypto hadn't crashed right now.
BTW, I remember you mentioned having converted the HDB from the investors into BUSD. Have you also turned it into fiat yet? (Not that it matters too much, since either coin is relatively stable, with only minimal effect of the crash.) Before the crash I was playing with the idea of powering down some HP and turning it into HBD, so I could put into your project even more before the pre-sale ends. But with the current HIVE price (though I'm glad to see it's coming back up slowly) I don't see that happening. Sorry. So I assume things are similar for other potential investors, whether they were going to use their BTC, HIVE, or other non-stable coin for it. And yes, under these circumstances I think it's quite reasonable not to buy into the Camino Viejo.
As for the commissioned deal, does that mean that if you find someone who buys out the silent partner, you'll get a percentage?
