Hi Ivette. You should get a buyer's agent to work for you. They should be paid by the seller but would be working for you. A buyer's agent can guide you on offers and can make sure that your offer is submitted. They can give you expert advice, so you don't overpay and can answer your questions exactly, not in a general form like here on Trulia. As Javier and Anna said, a cash offer is stronger because there is little chance of it not going through, where as a mortgage is an iffy proposition.
