The city may condemn a property for health and safety reasons as well as abandoned property. In order to condemn a property the city has certain procedures they are required to accomplish before they are allowed to have property demolished. The procedures are drawn out and normally require some form of court action.
During this procedure the current owner of the property is notified by mail and any other means that action is being taken against the property, and they are required to appear in a court room or planning department to defend themselves against action being taken by the city..
In some cases, there are groups that might consider the purchase of the property for history purposes. In order for this to happen the group would be required to partition the city to allow them to purchase the property and present the city a plan as to how they would restore the property and the purpose the property would be used for.
You also have a time frame in which the city would allow any action by a group. It might be that this eyesore has gone through the process of being demolished and the city would not entertain the property being restored under any condition.
You would be required to speak with the city planning department to find out the status of the house. Once you have established the situation and phase the property is in, you might inquire as to what can be done to save the property.
If you get no satisfaction from the city planning department, you might approach the city council person where the property is located to see if this person would be of any help in saving the property. Some small cities do not have wards or council districts, so any councilperson would do.
If the city council would not be helpful, you might consider taking the matter public by going to the local TV and print media. Normally there is a TV station that take up citizen concerns. Most newspapers have a citizen section where you are able to voice your opinions.
I hope this has been of some benefit to you, good luck.
