This is a tough one. First, I don't think MPs shoupd be landlords, but:

• She wanted to sell the house
• She waited until the renters contract expired
• She did offer a rolling contract to the current renters at their existing rent until the house sold
• They declined
• She put the house on the market and opened it up to any short-term renters who wanted to stay there while it was on the market
• She listed it for current going rate
• Someone took it
• The house is still for sale.

To me, there isn't much wrong with that, what is wrong is:

• She didn't wait 6 months. Not only is this terrible, but the optics are horrible and she should know that
• She is using a tenant agency that tried to charge them a ton of move-out fees (She did have them canceled)

And..

She's the HOMELESSNESS MINISTER?!?! Sheash.

Edit: Some additional context from UK peoples - some letting agencies will relist your home without telling you. Fun stuff.
