If prices have not gone down much yet is because supply is very low in some areas.

We intentionally invest in secondary and tertiary markets in areas with strong enough supply and demand numbers in an attempt to add us a bit of extra "insulation".

Regulations, regulations, regulations.

This isn't a very technical approach but it's a way to start without going to an agent that has access to supply and demand data that is owned by the mls.After you have done your initial study of these census tracks with this data, I would start to build relationships with some really good Realtors that are willing to work with you and share the mls data of inventory (listed homes) over time vs demand (sold/pending homes) over the same time frame for those particular areas.

Then find the zoning bylaw or regulation for your municipality.

If you supply the details, we can help you think it through.

The ones I am working with are saying that they "mostly" business as usual and aren't being hit by the regulations that are affecting the banks. 

I think regular office could see a massive oversupply of space even with no new buildings constructed except for highly supply side constrained areas.If there is for example 10 million sq ft and 90% occupancy and existing tenants now want 40% less space then existing inventory of lease able space could skyrocket even with no new construction.

You'll have no problem using an FHA loan for example in a rural area, but might have trouble in a red hot area like NE Minneapolis since sellers don't want to deal with the headache of inspections, regulations, etc when they can get asking price in 2d from a conventional buyer.

If you are not following Dodd frank and other regulations on the lending side that’s another issue.Love to get @Jay Hinrichs take on this
