IRS, Immigration, just some real basic areas off the top of my head where you can get in real trouble. 

There is the constant stream of new immigrants as well who are finding it extremely difficult to sustain themselves here after their savings have dried up.

All it takes is change in immigration policy and that will come to an end.

So many good points mentioned here like low supply and high demand which is one factor, cheap money (low interest rates), immigration wait lists, great place to live (when foreigners research Canada, they immediately are drawn to BC, landlocked and the likeness of Vancouver to Sydney Australia (when I was born and raised and saw property continually climb year after year to this day!!)

I'm an immigrant, currently working on H1-B visa.

And, top that off with the new administration basically opening the borders to refugees and significantly increasing the number of immigrants we allow into the country, the demand for housing is only going to increase. 

As immigrants, we are sometimes drawn to invest in where we come from, however, we should be careful not to invest out of emotions. 

In Denver compared to Atlanta, I'm guessing material prices are higher (we're on the coast), you likely have more strict building codes to deal with the harsher weather, and you most certainly have fewer undocumented immigrants and unlicensed contractors competing for business and driving labor costs down.I'm curious to see all the photos, and see the differences between construction in Atlanta and Colorado.

Stop spending, turn on keystone pipeline/coal/nuclear, cut off illegal immigration,  tune up immigrant work visas, tune up white collar immigration.  

The new gate way for Asian immigrants is now Atlanta, much like what New York and LA used to be in the 80s for Chinese, Korean, and Indian immigrants.
