Granny flat has no form 21 final certificate

Hi

There are 2 weeks left to settle for a property with a newly built granny flat.

There are a few things that have not yet finished. For example, electricity has not yet separated from the main house. There is a gap between window and wall. It should have been filled with cements.

I asked owner for warranty certificate and he said he does not have it.

I got the builder's name off him and I called the builder.

I was told that the owner still owes the builder $11250 and the owner does not want to pay. So the builder stop working on it.

At this stage, what should I do?

Thanks in advance.



The actions that I can think of at the moment:

1. ask owner to pay $11250 to the builder

2. ask owner to reduce $11250 from sales price and I will pay the builder

3. negotiate with this builder and ask how much he will charge me to finish the work (hopefully much less than $11250)
