I’d just say with the banks and approval, sometimes it’s still safer to put in an offer subject to finance with your banks name.
Even though your banks can give you a generic pre:approval amount, in the fine print there is still subject to final property approval etc and pre:approvals usually only last a certain period of time, if you do put in an unconditional offer you can loose your deposit if the loan falls through, I don’t want to scare you, just something to keep in mind.
Also if you really love a place and it goes to auction, if your finances are almost in place it can be a good idea to register as a bidder, if it gets passed in you will generally be top of the list to make an offer.
Also a building inspection can be worthwhile, make sure they are thorough, ask around for a recommendation, I know a few people who have found big white ant problems, that can be very costly.
