You won't know until the valuations come back.
If the market hasn't moved a great deal - then it's likely the valuation will remain the same as purchase price.
If the market has picked up and/or there's been some improvements to the property since purchase (which it doesn't sound like)...
What's your tolerance to risk like? Can you sleep at night if your LVR goes beyond 100%?
I'm an advocate for releasing equity whenever you can - but you need to consider the downside of leveraging up in a market which may have peaked.
