@Rashmi Chanduraj, Philadelphia is block by block city.

Sometimes they just place concrete blocks on the slab, but it is really the same thing. 

You can Google him or DM me for his info since the forum filters block contact info that's posted.

There's little regulatory law beyond a couple private letter rulings. 

This is a potential block against a bankruptcy filer transferring the property to another person/entity who then files another bankruptcy to continue staving off the foreclosure sale.- at least in Indiana, when a debtor has a previous bankruptcy dismissed in the last year, there is case law to support that the 30 day stay after the first dismissed bankruptcy within a year, cannot be extended after the expiration of the 30 days. 

You are a homeowner on the block with knowledge of flooding. 

I'm assuming that the letter alone will be enough for 30% of tenants to start paying little by little, but I'd be happy to report back if there's any interest.  

@Jillian Dior Off market friendly conversation, letters to owners, and calling landlords asking if they want to sell. 

This may require an executed "appraisal transfer letter."

It is the worst on the block.
