This is someone looking for a handout or help, not a real story. This happens all the time, it's not like it's a new thing.
When you win property (car, house, abandoned warehouse, whatever) there is a simple decision to make: Can you afford to own a <thing> worth $X.
If I win a $200k car, my question is can I afford to drive a $200k car. I can't. So clearly I need to sell it.
This lady can't even come close to owning a $550k house. She, of course, needs to sell it. The income would be the value she sells at, not the made up $550k so she'd owe taxes on whatever she sells the house for and keep the rest.
Them even mentioning forfeiting it is retarded. I'm 99% sure taxes would be due next April if she takes the house now, plenty of time to sell it. Even if taxes were due immediately you take the house, tell the IRS to suck your dick and wait while it sells.
