I don’t think there is anything fishy with the finances. Stephanie never gave the impression, she herself is short for money. She never hid that she has been highly supported by her parents in that department, but she also hasn’t pointed it out directly. But everyone watching and listening can see it. The travels (I had a look at some hotels: £££), buying a Chateau mortgage free, maintaining it without breaking even in 15 years, the renovations are not just some hush hush cheap botch, getting your hand not just on one but two London flats- one bought at a time were prices were already completely through the roof, she wears some very expensive brands- and they are still expensive when you buy them second hand, her love for those extremely expensive porcelain (a plate for more than 200€ is nothing but insane), the alcohol brands, the food....
She and Nick were obviously smart enough to distinguish the Chateau from their personal wealth. (I don’t buy the “not a business lady narrative at all.) It’s absolutely fine to not go broke to renovate a Chateau. They always planned on re-selling and I don’t think that’s completely off the table (iirc she mentioned this in the flower show vlog). When people started asking for ways to donate so she could make more progress in renovating the Chateau, she set up the Patreon. I think it started for renovating the Chapel. People loved the content and were willing to pay to get more of it. And they loved the Chapel and many wanted to specifically donate to get it done. The vlogs definitely had a different vibe and were more relaxed, sprinkled with jet set lifestyle fun and had well executed renovation content. I think people that haven’t watched from the start have a harder way to see that. Especially as many parts of her “wealthy” lifestyle aren’t as visible at the moment.
Since the beginning of the year, you can definitely tell that things changed though. I think it’s sad that it’s not clear what renovating projects the Patreon money goes to at the moment. That, I find fishy. The gift channel is just embarrassing and looks greedy.
But her personal or her parents financial backgrounds aren’t really that mysterious. Her parents made money and she (and Isabelle too) probably mostly live off good invested stock portfolios. Renting out a London flat is also not a bad scheme, but it seems she doesn’t have to do all the time.
