Lincoln City chairman Bob Dorrian says relocation may be the only way to secure the club's long-term future.
The Imps have had a ground at their current Sincil Bank site since 1895.
But Dorrian told BBC Lincolnshire: "The stadium isn't really fit for the modern day. We have no facilities to derive any commercial income from the ground.
"I would like to think something will be on the table within the next four years. The long-term plan is to make the club attractive to investors."
Dorrian, along with corporate directors the Lincolnshire Co-Op and the Lindum Group, have invested more than half a million pounds in the club and are to establish a holding company to administer shareholdings.
But he denied that that was the first step in separating the Sincil Bank stadium from the club itself.
"Lincoln City Holdings Limited will hold Lincoln City shares, nothing more, nothing less.
"We've heard rumours that we're going to split the ground from the football club but that's absolute nonsense.
"It's a new business model for the club. The old one hasn't worked, so nothing ventured, nothing gained."
However Dorrian conceded that the Blue Square Bet Premier club would have been in serious financial difficulties were it not for the latest investment.
"At the end of February we may have been in a position, if things had stayed as they were, where our March payroll would have been in jeopardy," he admitted.
