That's insane! Hopefully it gets resolved.
Maybe they no longer want to sell and figure if they just don't answer, the whole thing will fall through? Very weird.
Dont make the assumption you will win.
If you do not close by contract date they do not have to offer an extension, unless it is written in the contract.
You wouldnt want them to sue you if you werent approved and couldnt obtain financing. But some owners have sued thats why in most contracts it is contingent on financing. But not all contracts, so make sure you know what your signing.
Every contract either covers something or covers nothing, so until you are absolutely sure you have had an attorney read your contract and explain it in layman terms, no reason to threaten anyone as it may come bite you in the b***.
I haven't ran it by an attorney but we did have a contingency on financing which we did obtain. While we haven't had an attorney look over the contract my realtor is the one who pointed out we fulfilled all of our obligations in the contract and they did sign the addendum to move closing from Jan 31st to Feb 1st, and they saw the settlement document at that time.
Would be pointless for them not to grant a 1 day extension.
So assuming all went well and you closed? CONGRATS enjoy your new home.
