I spoke to my dad about locating money lenders and he told me I'm wasting my time because no one will give me any money if I don't have an income.Secondly, the people close to me are telling me that most of the money lenders are probably scammers, trying to take my identity, so I cannot trust anyone, And thirdly, my dad is telling me that because I am 18, I am at no legal age to sign any formal contract for any loans..

How can I protect myself and legally help him sell commercial acreage.

Also can I legally tell tenant that I won't be accepting rental assistance?
