That is a great nugget to have in my back pocket going into the Guam market.

Has anyone else discovered this "gold mine"?

I picked up a few nuggets of information and a TON of leads.

Is there a specific nugget of info that you can trace your investment career back to?  

This is considered the Berwyn Gold Coast (between Pershing Rd and Ogden).

Every single person I've talked to in realestate said I have a gold mind on my hands considering the fact that I was able to pick up a 4plex for $230k in my area...

He who has the gold makes the rules, and the banks and insurance companies have all of the gold...If Daniel followed your advice he would not be breaking law - per se, but he would be violating a couple of clauses which opens him and his partners up to liability. 

You may want to think about a tiered structure. 5% for check collecting. 7% for check collecting, and paying other recurring bills like landscaping, or any taxes or utilities the owner pays. 10% may be the "gold" level of service and may include yearly tax assessment evaluation and fighting with the assessor to bring down the assessment if needed.

Let me give you a couple of examples.From 1998 to mid 2002 gold spot prices were less than $300/oz.

Do not get any other kind of attorney except real estate attorney and get one that is worth their wait in gold, check around.
