In many small towns (such as the one for which I work) the GIS database is administered by the Assessor or Tax Collector (with the help of a GIS contractor).  

@Andrew BrecherTo expand on @John Casmon point I have listed a number of datasets that I've found in my research, which will provide you with a number of key performance indicators (KPIs) that you can use to evaluate real estate markets at all levels.Census Bureau: American Community Survey (ACS)The ACS was launched in 2005 and is administered every year by the Census Bureau to roughly three and a half million households in the USA.

The housing authority that administers the Section 8 program reviews it to make sure nothing in it conflicts with the terms of their program.

There have even been wars fought, warm and cold, over exactly how it should be administered, how much should be contributed, and by whom.Depending on your spiritual/philosophical belief system, for several hundred thousands of years, or several thousand years, people choosing to live together have contributed something to the group cause.No one 100% agrees with government spending.

You will want to contact any and all of these people who will be acting to administer the estate. 

To be clear.....they do Not own the property, they administer the mortgage.  

My own experience with a homepath investor loan was a complete waste of time.It's a good idea, that's five years too late, and will be administered by the "Pig-men" at the mega banks.

I want to quickly get my GC license to administer and coordinate anything construction related for real estate investors in the Los Angeles area. 

The trustees who administer programs that fit the code decide what investment options to make available to customers.

According to the prospective tenant, MBQ would pay up to $910/month and the tenant would be allowed to pay up to $490/month.I think this is one of the things that might be different in different regions or by the PHA that administers the program in the area.In a couple of my places I happened to rent 2 out to different section 8 tenants within about 2 weeks of each other.
