I believe its more blue states that have these laws.

But, Jefferson County has a special law that makes such sales not void. 

Plus (I'm assuming) an HOA on the town home.Perhaps, if the larger home you all purchased had a legal separate residence...like a basement or an in-law suite...that would allow you all the tax advantage?

We have a son and daughter in law who lives near Cincinnati who just lost their baby a few months ago and it will be nice to have a place to get together and visit them while we are at the conference if they want to stop by as well after work to see us.I saw a fireplace in the photo!

If your talking about strictly minimizing holding costs, putting it back on the market as soon as possible is the answer.

How strict are they?

@Colten RoneyThere are many accountant's/CPA's on this messageboard who frequently provide value to the forum by answering questions and posting updates to the tax laws as they relate to real estate.

I'm in MN and I'm not sure if the laws about HOAs vary much from state to state. 

You really just need to take some time to research and learn the laws specific to your state.

The MLS is not a government entity, so they cannot punish you under the law.
