Owner Financed Land for Sale in Iowa

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.

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.
