Iowa Owner Financed Land
If you are looking for land in Iowa and aren't sure if you have good enough
credit to qualify for a traditional loan, you may want to look into owner
financing.

Many land owners in Iowa offer owner financing on the sale of their
property.  When you buy land that is financed by the seller, the seller
holds the title until the payments have been completed, so there is less
risk.  Because of this, an owner financed land deal usually does not
require a credit check or large down payment.
