If you are new you should really not be casting at all, instead start by studying the basics before expanding your knowledge.
Generally spells won't work until you know at least the basic information.
This is generally made up of: meditation, centring, grounding, visualisation and learning what is real from fake.
There are many forums on this site that are good, but I would recommend looking at "Starting Out" and "the basics expanded" they cover a great deal of information and can be found by using the sites search bar.
Why is it that you want to remove the ghost?
If you want to you could cleanse the house to remove negative energies but that is a personal choice.
Well, if you're serious about learning how to do magic and with starting from the rock-bottom then you don't start out by casting spells, you start out by learning how and why magic works.
You see, there is no such thing as an "easy" spell or a "beginner" spell. One either understands how magic works and has mastered the basics...in which case the magic will work..or you haven't done that sort of work..and no spell will work no matter how "easy" it seems.
Casting a successful spell involves much more than finding some spell on the internet or in a book, saying some words, lighting a candle, waving a wand of any of that sort of thing. In order for magic to work you need to understand how and why it works in the first place. Grounding and centering, visualization, focus and intent, energy manipulation, etc are all necessary first steps to even begin to have a chance at a spell actually working...and more importantly to prevent a spell from back-firing on you.
So, my advice for anyone who is truly serious is to start by reading a few books and practicing the exercises those books will give you. Once you have mastered the basics you won't need anyone to give you spells, you'll be able to create your own spells that will be far more effective than anything you find on the net. Here's the books I suggest:
"Before You Cast a Spell" by Carl McColman
"Spells and How They Work" by Janet and Stewart Farrar
