Bond Buyer In Louisiana, Can A Bond For Deed Be Executed On Real Estate That Is Already Financed?

In Louisiana, can a bond for deed be executed on real estate that is already financed? - bond buyer

My husband and I moved to New Orleans. We have to sell our property on the North Shore to purchase the others in the parish of Orleans. We have customers who are interested, but concerned about their ability to obtain financing. I still owe on the property (approximately $ 118K), but I wonder whether we can link, but we owe it to her.
