I'm a semi-long time reader of these forums and a first time poster. And with that having been said I'm also a first time home builder (and purchaser). So, if my questions seem somewhat silly please excuse my lack of knowledge.

My partner and I have just begun the whole building process, or rather, are currently going through the motions before the building can start. Our land is located in the western suburbs of Melbourne and we will be settling that around mid December. Assuming, of course, that the bank doesn't do anything else to delay us.
But now for the question(s)...
We will be attending all our selection appointments over the next few days and then going to our Tender appointment on December 4. Now, the builder we are going through state to us that upon their presentation of the fixed price tender, if we then sign, we need to pay the 3% deposit. I'm essentially confused about this - are we supposed to then pay them over 7k (which is roughly 3% of the initial quote we got) right then and there? Or are we able to walk away with an unsigned tender, present that to our bank to get an approval and then we can tell the bank to release the 3% and give that to the builder? Having asked that, if we decide (or maybe we shouldn't?) to sign the tender on the day are we supposed to sign it subject to finance like we did when we were first purchasing the land? Or, is the tender not as binding as a contract?
Again, I apologise if my questions are quite silly (with answers I should already know) but I don't know many people who are building brand new houses. And one of the main things my partner and I have decided on is to that we wanted to research and be armed with as much information we can before embarking on this journey because we didn't want to be in a 'surprising' situation and looking back and saying, "Oh my, we should've been more prepared!" We've definitely prepared as much as we can and we both thought that if something 'bad' happens it would be our lack of preparation. But to date, we've only had glitches arise due to the fault of other parties - namely the agent at the land sales centre and kind of the land valuator. But I've made my peace with them. Haha
And my final question...
Should I be getting a solicitor/conveyancer to look at the tender documents or would that just be at contract stage? While I'm at it, can anyone recommend a solicitor/conveyancer that I can call upon? Our current conveyancer only specialises in land contracts so I'm afraid we won't be needing her services after settlement.
Thanks in advance!
