Financing Advise for Land/Home purchase?

My dream is to buy/live on 1-2 Acres of land and graduatly build new stuff on it (House, Pool, Nice backyard for dogs and horses). Its not in my budget to build a house. My ideal plan is too buy a mobile home (New) and in 10-12 years build an actual house on the land. My question is what would be the best way to get a ~$105,000 Loan to purchase land and put/build a mobile home on it? Can I get a mortgage? I really need the loan to be 30+ years since I only make about $30,000/Year. Also my credit score is ~760 and I'm 25 years old if it matters.
