It’s guiding the client through the process – from assessing zoning rights, access and easements issues, to understanding and feeling comfortable with today’s variable market conditions” says Eric. “It’s the little nuances that are so important but are easily overlooked. It is important to ensure for the buyer a seamless transaction that doesn’t come back to haunt them later”.
