Socialized Housing Cost Breakdown

During my defense for Design 9, my panel said that some socialized housing cost are readily available on the internet with complete breakdown. I needed this information sa data gathering ko but i was not able to put it in my paper yet before the defense because I emailed govt. offices and they were not able to respond. I’ve been searching the net for quite some time and cannot find a comprehensive breakdown of cost for this. Does anyone know how I am able to get this info?

Thanks so much in advance.
