If the gvt wanted to speed up home transactions, then do what’s done in Scotland and Australia. When the sellers list the home they provide a pack of all the relevant searches (similar to what is proposed), and an offer is a binding contract once accepted.
that way there’s no gazumping or gazundering. Home buyers have to have mortgage in principle’s already established, so they know what they can offer, and then the home seller chooses their sale and the contract is signed. Job done.
Get rid of the ridiculous back and forth that currently exists. Lawyers already offer indemnity insurance for virtually any unknown quantity in a house transaction for a very modest fee, this would essentially become standard because the contract can’t be exited from once the offer is made.
