To say enough is enough now

[HopefullynotNCfail]

NC as outing.
I had an offer accepted on an onward early autumn.
My buyers by Christmas (understandably) said they weren’t willing to wait anymore. The legal side of my onward was all sorted, and the agent reassured me it was just a case of signing paperwork and agreeing a date now. So I broke chain to keep my buyers and went to stay with an aunt for what I assumed was two weeks.
We are still here. While my family would never say I am aware I am starting to outstay my welcome. I hadn’t gone into rented as we were “there” so I didn’t see the point! It’s just been an issue of getting a date agreed.
We had finally agreed to complete next week (three houses in this chain) and yesterday (I have my vendors number) heard that her onward isn’t sure about next week being convenient.
I’ve had enough. I replied to her saying thanks for letting me know, but have gone to the agent (who is selling the one I am buying and the onward) stating if we don’t complete if not next week the one after I’m out. As I’m not convinced top of the chain really wants to move (divorce is forcing the sale), and while I have sympathy with her position I’m not waiting for her to want to get Christmas (fair enough), kids going back to school, most recently half term… and now god knows what out of the way before she sells.
I’m hoping this is the push she needs to go but I wish id been firmer sooner!
Arrggghhhh

I should add I can’t afford a 6 month lease somewhere and the mortgage/bills for this, before it gets suggested!

Bloody hell, I bet the agents are getting pissed off too. Have you been looking at other properties? I don't think you are wrong to give a date though

Oh I would have been climbing the walls a long time ago, you have been more than reasonable.

Definitely not unreasonable! If you've left your property has the sale completed? So you are now bottom of the 'new' chain.

When you say you can’t afford to rent, what about the money you got from your sale (that you’re going to buy the next house with)? I think you’ve done the right thing and I would carry your threat thought but you should be aware that if it doesn’t pay off and your sellers have to pull out (reasonably likely in a forced sale) you’ll be back to square 1. In this case it doesn’t sound feasible or fair to stay with your aunt for 3-4 months whilst you find a new place, so you may have no choice but to rent your own place for a while. That’s what most people who break the chain do, and they consider the rent as part of the “price” for keeping their own buyer/ being in an excellent position to buy the next house.

I can afford to rent but couldn’t afford to go into rented and then complete on this one in 2 months time while tied into another 4 months of rental. Is what I meant!
If I went into a rental I could suck up a month of cross over.
