Where do you get loans to buy properties?

[Kirk Hause]

I own one property free and clear.  I have mortgages on two others.  I cannot get a loan for another one.  I buy low income property ($50,000 and under).  Some companies will not give me a loan unless the property is $75,000 or more.  Our bank will not give me another mortgage because the two properties were just purchased in the last three months so I have not shown profit on my income taxes.  Where do you get loans to buy low income properties?
