Answer:
Timothy should apply for a mortgage loan.
Step-by-step explanation:
A mortgage loan is used to buy real state while putting a lien on the property being mortgaged. As Timothy wants to acquire real state (a house in this case) his loan is secured on the borrower's property (the same house). A lien, in this case, would be a security interest granted over the house as property to secure the payment of Timothy's debt.
