I wonder if judicial solutions can ever be adequate as police can simply say that an investigation is ongoing for years. And determining whether ongoing possession of seized property is legitimate involves disclosing investigation details.
How is that different than, say, indefinite detention? It’s obviously not implemented perfectly, but habeas corpus is uncontroversial at least in principle. I don’t see anything mechanistically unique about property seizure that would make this tricky to solve.
The most famous example of this kind of use of eminent domain was the Kelo case which went to the Supreme Court. By 5-4 the court rules it was permissible to use eminent domain to get the land to build a campus for Pfizer. (The majority was Stevens, Kennedy, Souter, Ginsburg, and Breyer.)
As Justice Sandra Day O’Connor wrote “The specter of condemnation hangs over all property. Nothing is to prevent the State from replacing any Motel 6 with a Ritz-Carlton, any home with a shopping mall, or any farm with a factory.”
After all of this, the land didn't get built into a corporate campus:
>...For nearly 20 years since the ruling, the entire Fort Trumbull neighborhood remained a vacant lot after being bulldozed by the city; a neighborhood once teeming with families who resided there for generations was home only to weeds and feral cats. The economic development the city promised the U.S. Supreme Court would materialize—if only the government could get its hands on the land—never materialized, even after spending more than $80 million in taxpayer money.
There was a proposal back in the discussion of extending copyright to be "forever minus one day" by the maximalist camp which included Sonny Bono, so there are hacks around "indefinitely".
Hmm, does my money have the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed?
