My new home construction closing date has been pushed back by almost a month and I already gave my 30 days notice in my apartment! How f+++ed am I really?

Long story short, the construction rep just gave me notice that my closing date is now 25 days later than previously estimated. I have no way of knowing whether they’ll push it back again. Luckily for me, my apartment managers let me amend my rental release date to match, which I just signed for them 2 days ago. If they find a new renter for my unit willing to move in before my closing date I’m gonna be SOL.

Has this happened to anyone recently? How did you handle it financially/logistically? Were you forced to be a hobo for a week or a month? I’m hoping for the best but preparing for the worst, and advice is appreciated.
