Loan for Building

Hi All
Purchased an IP in May 09 with DA in place for 1 unit dwelling at back. Loan with SGB lo doc product. I am now looking at building at back.

Can anyone tell me what my options would be, with all the changes to lo doc not sure whether SGB lo docs will now do this??
Purchase price of IP was $300K, approx value $400K.

Any assistance would be great.

Cheers, MTR
They will as long as you can provide last 2 BAS and 3 months trading statements.

If not and you need to refinance then you have a problem.
