I'll be waiting for cheaper bitcoins and really low cost per transaction

How much cheaper? $350 is good enough for me.

I hope it goes sub 100 so I can sell my house my car and my laptop to buy a lot more

This is probably not the best of ideas. If you were to disregard the fact that it will generally take months to receive funds when you sell your house (as it takes months to close on any potential sale), putting all your money into bitcoin would essentially be putting all your eggs in one basket and
the price of bitcoin is far from certain to rise over time
