As construction workers lay track for the Central Corridor light rail line, government and businesses are fighting a quiet battle over payments for nearby property.One thing is clear: It pays to flex a little muscle.While some property owners accept early government offers, those who deploy a lawyer, an appraiser or both can get a lot more money.A case in point is the vacant Bremer Bank property in downtown St. Paul, which sits in the path of the line. Ramsey County valued it at $1.5 million and the state appraised it at $2.25 million.But it fetched $2.65 million after the owner contacted an attorney, argued that the property was worth much more and signaled that he was willing to go to court to prove it.
