The filings give the names and addresses of the person who dies and the person who is the estate'e administrator.

On their website it states regarding rehabs that projects that will require to comply with IZ are:rehabilitation projects that are expanding an existing building by 50 percent or more and adding10 or more units.Just reading this, its unclear whether you have to have affordable units only if you expand a building by 50% or if you expand a building by 50% and in doing so add 10 or more units.

For a all of the before, rehab and complete images along with the nitty gritty details, I actually kept a weekly blog here on BP you can check out here: https://www.biggerpockets.com/forums/67/topics/442...Any other questions, please feel free to send at any time. 

After an application is received (which is after more rounds of pre-screening) I'd look into something like a deeper check into credit and address history as mentioned above @Carrie Albertson.

Assisting the Commonwealth of Puerto Rico and local governments in re-allocating existing federal resources toward disaster relief – HUD's Community Development Block Grant (CDBG) and HOME programs give the State and communities the flexibility to redirect millions of dollars in annual formula funding to address critical needs, including housing and services for disaster victims.

So when there were details/retouches (as expected after a big remodel) he preferred to address them himself, instead of having someone inside the house.

This is because the properties are usually (but not always) distressed and require rehabbing before a conventional lender will touch it.  

The price however is 20%-30% less than what you could get for the same square footage almost across the street with a different city address.

I think the current address might turn off some potential renters/buyers (haven't decided if I'm going to fix it up and keep it,  or wholesale it).The house number is 666.  

[Even for their "Delayed Financing Exception", they won't lend against your rehab expenses; JUST the purchase cost].
