Use PRS conveyancing tell them I sent you.
Some rea will allow a verbal offer, some will make you put it on an offer form.
Once its agreed to, rea does up the template contract, its about 10 pages. This has your name (or name you're buying in), your address, the purchase dollar amount and whether its subject to finance and any other conditions. You sign this and initial all other pages. Send it back to rea.
If vendor likes it (and they do, that was the point of the pre offer dance), they'll sign and initial that same contract and send it back to you. Forward it onto your broker and conveyancing firm.
The rea will then send you whats called a form 1. Its a bundle of searches and disclaimers about the property ie encumbrances, easement, land tax etc. This is usually about a dozen pages. You need to sign the one that says ive read all of it and send it back to rea.
From when you received the form 1, clock begins on 3 biz days of cooling off. During this time I usually do my b & p. By the end of that your deposit is due (usually 1000 but some rea will try for more). Make sure you get a receipt. Id also organise your insurance now.
From there you start your finance tango with your broker. My last couple of deals ive gone sans finance clause so I dont remember the duration on finance approval.
Then its just a waiting game. Settlement is typically 42 days but can be any amount you put on the contract.
If interstate, make sure to tell rea you authorized them to give keys to PM as they have refused me before. Also see if you can do repairs or tenant showing during the process
