If you have a house or a building that you want to finish quickly without using life style points, make sure you have paid for the building or house already, press the home button on the iPad or iPhone so you are at the main screen. Then press the home button twice, you will see the sims freeplay app in the history, put your finger on it until it shows a minus sign on the corner and then press the minus to delete it from the history. Then go to settings and then do to general, then go to date and time and switch the set automatically bar to off and then change the year to 2038. Then go back to the sims game and your building or house will be finished, you will also earn some money and experience points from houses and buildings that were previously built. When you are have finished the building or house you can switch the year back to the correct date. Enjoy!
