Today we met with NAB after meeting with Hume last week. The initial impression is that the two are incredibly different. With Hume not being focused on profits, the conditions of the loan (as in locked for first 2 years and interest only for the build) gives us the security we need.

The rate is 4.2%, a 0.1% discount on the advertised price. While it may not sound like much that translates to thousands, maybe even tens of thousands downt he track.
We’ll continue to visit banks over the next week or so, in the hope of either finding a better rate, or better conditions, or in the best case scenario, both. We found neither at my current bank, NAB.
