How can I Finance these 4 properties

[Cardwell Thaxton]

There are 4 single family properties I want to purchase. The total price is going to average $50k to $60k each. They are not together or being sold as a package. I plan to put 20% down on each one. I want to finance them with the rents paying the loans. I'm told that no mortgage company is going to finance a $40k-$50k house. I'm wondering if there is a lender that would allow me to bundle them together and finance the 4?

Or any creative ways to finance them all together?
