As for people who piled and overpaid in a small handful of markets based on herd mentality and "only invest in vacation markets" advice, yeah, I agree with this post.

Worst case scenario you can also just add some supplemental heat to that space (electric baseboard or radiant, space heater, etc).

He and his son spent all their time herding squirrels 24/7-poor management?

I've been wondering when the decline in occupancy and revenue might start to cull the herd of vacation rental owners.

He bought a 4.5KW electric radiant heater with windows open at night. 

It's like buying a suit of armor to bring to a pillow fight.This herd mentality, where everyone blindly follows the latest 'sophisticated' trend without understanding the why and the how, is not just amusing but financially draining.

The plan to time the market loses to psychology and fear of loss.For the herd.

Managing the infrastructure and all that is in that sphere. 2- Tenant Management: This is something akin to herding cat's, lol.

Of course that increases with thickness, the addition of insulation boards, radiant heating, rockwool, etc.

Great job on grabbing this and adding it to the herd.
