PRIOR TO CLOSING
Before closing on the house, there are other things you, your Lender, & your Realtor should go over.
A title search must be done to make sure there are no claims on the property and that the seller can provide a marketable title. If there are claims, the seller typically would have to pay them off before the closing unless the contract states otherwise.
The lender will require title insurance to protect themselves if problems do arise with the title of the property.
You will typically need to get homeowners insurance prior to closing and make sure that you have the receipt.
