Nobody is this stupid. You're being intentionally dishonest.

USDA isn't the private sector. There are strict rules against firing the vast majority of employees. It's why Trump has largely gone after probationary employees, as they have less protections. Even that has been wrapped up in several different ongoing court cases.

There are also mortgage forbearance programs designed for temporary job loss. Even without them, foreclosure is a lengthy process. It's not something that's initiated after one missed payment.

So for this story to be true:

1. OP, a progressive Twitter influencer, lives next to a hardcore MAGA republican. Unlikely, but relatively common
2. Said MAGA republican is also a federal government employee. More unlikely, but still relatively common
3. Said federal government employee is among the roughly 10 percent of government workers that are probationary. Relatively rare, but not unheard of
4. Despite being new to federal employment and federal employment known for someone that you do for the long haul for pension reasons, OP's neighbor has the money to buy a house. Relatively rare, but not unheard of
5. Despite having the finances for a home, is in such dire straits that the only option after one missed paycheck is to sell their home. Very rare, but not unheard of
6. Despite being very into politics and a government employee, is wholly unaware of the pending legal actions against said firing, including the current rulings reversing the staffing cuts.

All of this is possible. The world is a strange place. However the confluence of all those things being true is highly improbable, perfectly matches the "dumb conservatives gonna regret their choice" narrative progressive influencers push, and is sourced from a platform known for being full of misinformation and bait.
