From what i understand, it will just be like renting the house from maybank, so you pay rental which is lower compared to normal housing loan, i guess? After 1 year of renting, when you opt to purchase, then maybank will convert it to loan as per the SPA price previously signed. So it means the rental you previously pay, will not be offset with the loan amount. That is how maybank earn i suppose..

Also need to take into consideration, its like renting, those major renovation I don't think its allowed (i.e hacking of walls, etc).. unless you want to incur the restoration cost in the event you decide not to buy the property.
