The most common way to raise the required funds it to get a bank loan, but you'd need to secure it against a property. If your parents own their house then that could be an option for you. No flight schools that I know of will sponsor you through the training on the condition that you repay them when you get a job with an airline. With some cadet programmes the sponsoring airline offers financial assistance in various forms, but such programmes are very competitive.
In terms of accommodation there is no one specific answer. Each flight school is different so you'll need to contact them to find out exactly what's included in the package.
Hope it's helpful.
