Before I process a rental in Miami, I always check on whether a Lis Pendens (first step in the foreclosure process) has been filed. This is one of the advantages of renting through an agent rather than a private deal.

There's no way to tell how long it will take for the property to go up for auction. As far as preventing it from happening again, you really can't - any landlord can stop paying their mortgage, and there's nothing you really can do about it.
All the best,
