One benefit of a HELOC from an administrative standpoint would be to minimize/eliminate the comingling of funds from the operations of each property.

I would possibly start by contacting the municipal zoning administrator or staff.

I value lenders' input very highly since it's real data based on real investment decisions. 

Like I said though, most come in about half that, so use $5k to negotiate and even if you get a 50% concession you could still potentially get it all paid for by the seller.I can run any addresses you might find here through the database for you and see if they've been inspected or deleaded for you.

Is there an executor/administrator in place? 

That being said here are the best way to find off market commercial and multifamily properties.Compile lists through a paid service like list source, Reonomy and CoStar or you can use free resources like Loopnet, CREXI, CBRE, Craigslist, tax database, brokers, property managers, title companies, multi family inspectors, appraisers, landscapers and other companies that service commercial and multifamily properties and driving for dollars.The real key is in how you approach the owners and then the follow up.

Public Administrator will then investigate whether a Probate has begun.Does anyone here have any experience with such cases? 

They should also get an EIN (Employer ID Number) from the Social Security Administration.

However, all that information is stored in a database and can be recalled in 1-2 minutes from my computer or any mobile device.

Though the name might imply that they only serve Joliet, they are actually the administrators of housing vouchers for all of Will County.
