Unfortunately, some of these so called Shariah-compliant transactions are not really. There is heavy debate around them, and as they say, the devil is in the detail.
For instance, my biggest issue with the scheme you mentioned is that, why would a third party come and buy the property and resell it back to you if they did not have an incentive (i.e. they have a buyer already lined up)? And can the contract be conditional that you have to agree that they sell it to you after they buy it? How is the profit rate set? Etc.
There are other schemes which seem permissible (e.g. a group of people agree to buy a house, then they find a renter and split up the rent between them. This way, the risk is spread across everyone, not just the one who owes the loan. The renter can then decide to buy shares of the house along the way). Of course, there need to be scholars who review this since there are small things that can render the agreement non-Shariah compliant.
