Speaking as a landlord and small-business owner...
1) If the market will support a higher rent, you should be charging it, Obamacare or not.
2) If the market will not support a higher rent, then you have to decide if being a landlord is the best use of your assets. If you have a better way to deploy your assets, you should do so, Obamacare or not.
3) Obamacare represents a first step in an attempt to bring some correction to the cost shifting that has been occurring in health care for years by adding some individual responsibility into the equation. I thought we were supposed to be in favor of personal responsibility - after all, the idea originally came from the Heritage Foundation (a well-known bastion of liberalism).
I too am a landlord and small business owner. I agree with #1 and #2. Although sometimes it takes a tax or other cost increase to adjust what the "market will bear". Also - if I have good tenants - I will weigh that into the equation as well. Sometimes it's the right business decision to not upset the apple cart. There's a lot of value in a low drama tenant.
#3, however, I respectfully disagree all to heck with. It represents the first step in a government takeover of the healthcare system. It was totally written by special interests, and in no way gets us closer to personal responsibility. How the hell does MANDATING that I have to buy your COMMUNIST coverage promote personal responsibility, comrade? I call iguana
Edit - CarmelHP - looks like we're thinking alike.
