Brittany,
First you need to determine the price. Additional steps that you must do before arriving at downpayment and closing costs are:
1. Contact a mortgage lender.
2. Get pre-qualified by that lender to purchase the home.
3. Decide on a loan type, or package. Different types of loans have different criteria that you must meet to qualify for it. Different types of loans also different types of minimum amounts required to put down on the loan.
4. Make an offer.
5. Get the contract ratified (agreement between buyer and seller).
6. Actually apply for the loan immediately after ratification.
So, the bottom line is: the answer to your question lies not with the seller or the seller's agent, but it totally up to you and your lender, based your ability to qualify for a loan. The majority of closing costs are made up of financing charges to pay the lender. The smaller the loan, the less the closing costs will be. Pay cash, and you will very little closing costs.
I hope that this helps. You best and first step must be to call a Realtor to guide you through this process and to find a property that is actually for sale. It seems that Trulia will put any picture of any real estate up on their site, whether it is for sale or not, or if it even exists or not. Notice that there is no actual price or listing agent for the property that you inquired about.
