I went to WWU and lived in Van for a while and always came across investors going across the border to park money in Whatcom county.

I know locally Brady Sullivan has a large renovated mill portfolio throughout New England, they're headquartered just over the border in NH. 

The house is a border line tear down and I got such a great price on it that I could still make money on the dirt if for some reason I couldn't get the issue resolved and had to tear down and a buyer eventually build something back within the property lines. 

Southern border is more flexible.

Partnerships, good agents and property managers are critical when purchasing across borders. 

Since the tax assessment process varies so widely around the country or county or region (and in some places even from town to town that border each other).

but the speculators of the day especially in the high desert out of LA always sold it that it would be the Next LA  well they been saying that for 100 years.. although Palmdale Lancaster has grown to be 50k populations maybe more and people drive into LA to work.. and Edwards airbase is there and it ebbs and flows with govmit jobs.. but most of the other areas are all what we call recreational lands  surrounded by nothing and or border vast tracts of BLM  and State lands and federal lands  be them state parks or federal parks.. just google it.. you will see.one needs to understand in your area lands were divided and lived on starting in the 1600s or earlier in some cases and well established in the 1700 and 1800s  these areas in those areas were still lands of Mexico in some instances and or Spanish land grants.

My wife and I grew up in Chandler and currently live on the border of Chandler and Gilbert in a county island.

I live on the border of Kops Park and Golden Valley.

Pikes Peak really focuses on El Paso County, but lines can often get blurred around the borders.
