rookie investor trying to get started

[Conner Wells]

I found a property that is for sale and its three acres that are all connected but 1 acre is undeveloped and inside a subdivision and the other two acres are outside the subdivision and has three mobile homes on it that are all currently being rented.  I guess my question is this considered a investment property to a mortgage lender and also what kind of loan could i get on it?  Because eventually i might want to build on the one acre that is in the subdivision but leave the three mobile homes and the tenants.
