There’s an old fast food restaurant near my neighborhood, boarded up, trash everyone, it’s a eyesore to the community.

Do you not have local ordinances requiring property owners to maintain them? Here’s language in a local cities code:

All buildings, both existing and new, and all parts thereof, shall be maintained in a safe and sanitary condition. All devices or safeguards which are required by this Building Code in a building when erected, altered or repaired, shall be maintained in good working order. The owner or the owner's designated agent shall be responsible for the maintenance of the owner's building.

Not maintaining it would result in fines, which the property owner could pay, but the city could either keep increasing the fines to the point where its cheaper for the property owner to sell it.
