Short answer would be yes, but as stated here, most likely will depend on your credit.
When my wife and I were looking for a new house with land, I applied through a federal credit union, and they gave me more than I thought I could afford.
When we found a house with with 8 acres (with an option to by another 32 acres with the house), we ended up going through a farm credit union. We bought the house with 8 acres, carried two house payments for a short time until we could sell our old house, then applied for a second loan for the rest of the land (we were told before hand that we could do this with the two loans). We did put a down a payment on the additional land and had a year of the purchase date of the house to apply for the land as well.
Bottom line is that we didn't want the house will all the land and a second house payment, thus the reason for "spliting" the loan for the "new" house and additional land.
We were surprised how competitive the farm union was, was a very pleasant (sp?) experience, and the realtor, laywer and farm credit union rep all knew each other and worked with us very well.
You may want to check any local ordinances/zoning (sp?) to verify that you can place a mobile home in the area that your looking at.
