Enquiry: sub-sale property during under construction..

kindly advise what is the procedure?

Developer allows consent to transfer during under-construction period with penalty of 1%.

How new buyer gonna buy if they agreed on the new purchase price as the old SPA price btw seller & developer is the first hand price..

Another SPA has to be made? if so how is the existing SPA btw seller & dev?

Need to wait until VP only apply loan or buyer just apply loan directly after valuation can be fetched?

How about redemption from financing bank? Seller is ready to pay RPGT and exit penalty to the bank..

Thanks alot if can help
