As far as the interest rate goes, that depends on your credit. They can direct you to lenders and mortgage companies that they have done business with but ultimately your credit determines what they can offer you. Not the agent.
I am now making some improvements to the home I am in just in case I decide to sell it but I am thinking I will keep it for rental income. This summer I am going to get the ball rolling. I hope that my information helps you and I wish you luck with your new home purchase.
