Considering those houses often go for below the value of the house or even for free, I wouldn't be that worried about scammers. You can easily get a small house with a fully leveled FC for 1-2 mil and some people will even offer the FC for free because they just want to get rid of it. But usually I'd advise paying half up front and half after. In think crafting or gathering for 2 hours to make those 2 mil back is better than spamming a plaquard for 2 hours.
