Freehold or leasehold? Bumi lot or non bumi lot? Even with freehold, is it freehold, the land title have mentioned any sekatan?

Freehold individual without restrictions normally 2 to 3 month.

Freehold with restrictions & leasehold normally take 5 to 6 month.

It's depend on the lawyer efficiency and government department. If you want to be safer planning, alway estimated longer time period. As now deepavali nearby already, and at the year end timing. A lot people start cleaning their annual leave and a lot holiday. So it's not guarantee what is the excatly timing. If you are rushing and want to minimise your lose. Then I suggest you can push your lawyer side maybe 1 week follow up 3 time, Monday, Wednesday, and Friday.

Both transfer born by Auction unit winner.

Example spa 1m
Auction win price 500k

So 1st transfer based on spa
Second transfer based on winning price or market value valuation.

Better make it faster, double transfer take longer time to process, so hope you can done it within 90 /120 day to avoid the late payment charges
