It's just Occam's Razor at this point.
Yes, these idiots will never cease to amaze me with how ridiculous, dysfunctional, and dishonest they are. That said, let's look at scenarios here.
1. DD owns a condo. She worked at a reasonably well-paying job for nearly 30 years. The condo isn't fancy, it's a bit small, and it's not exactly in the trendiest neighborhood. Perhaps a family member or two helped her with the downpayment. Meanwhile, she's an unusually tall, stocky woman who never had kids but was apparently in a long-term BDSM/swinging relationship instead. Her pussy skin is naturally greyish, as happens sometimes. She clearly has some hormonal issues judging by the way she carries her weight and her balding, probably PCOS and/or metabolic syndrome, which are both quite common in big fat women who work sedentary office jobs.
2. DD's mom owns a one-bedroom condo that DD's brother paid for immediately after DD's dad passed away. Mom went into hospital, so DD immediately moved in to the condo (so within the last year or so). Mom and DD lived together/are planning to live together in a 600 square foot, one-bedroom condo once she's well enough to go home. With Nader, too! DD has zero money or savings of her own to have purchased a condo at any point in her career, despite not having expensive things like a car, pets, or children. She's also a nearly fifty year old trans woman, who has been living as a woman for decades, well before it was the hip thing to do. She also got some pretty top-notch surgery at some unknown point, so much so that other than some discoloration, it's not obviously a fake. Maybe that's where her money went, I guess. All of this is based on the word of a clout-chasing whore who has a history of telling big fat fucking lies, some of which have been documented by the courts, and who is clearly desperate to get revenge on DD and Nader, as well as hang onto the last shreds of internet attention she's clearly addicted to.
Is Scenario #2 possible? Sure. Nothing would surprise me at this point. But I wouldn't trust Korvina telling me the sky was blue, let alone this other long chain of improbable events.
