Have to move 😩

We found out recently that our landlord is selling our house (but swears he's honoring our lease by including it in the sale contract to the new owners) by August 1. Baby is due June 26. He knows we're having a baby and is still moving forward with this right now. We live in a place that has a high cost of living so it will be very hard to find another house to rent, especially while I'm on maternity leave. This is my first child, my SO has 2 with his ex wife-which is also the reason we live here so he can see them as much as possible. I'm so sad I don't get to nest right now like I should be. It feels so hopeless and I really hate this stress right now. Thanks for letting me vent. 😕
