Dear Monty: My wife and I are currently looking for homes with an agent. We have received preapproval letters from three lenders and are still deciding which way we will go. Upon providing our agent with our preapproval letters (all for the same amount and similar interest rates), the agent called our potential lenders and asked how a high HOA fee or high-rise condo restriction would affect our buying power. We did not authorize this communication. We are looking at a mix of single-family homes, townhomes and condos in many different areas. We have yet to decide on a specific property. It seems like a premature conversation as a way to steer our search away from properties that he believes could be a waste of his time because they may result in unfavorable loan terms or lack of approval. Was our agent’s call to lenders and subsequent inquiry ethical?…
