Hopefully, you have a clause in your lease that states the tenant must return the property back to you in the same or better condition as they received it.You may be able to use this clause to warn the tenant to smoke outside or face damage charges as smoke damage is not normal wear & tear.

Normally, they would have zero tax because of the capital gain tax exclusion on primary residence, known as the Section 121 exclusion.

There are plenty of days when I wish I lived in a McMansion and had a hot car that would go vroom-vroom and everyone would take note of my mastery of the art of life.We all do.

I find it odd that they'd pay rent several weeks in advance (assuming it is for Aug 1) as first month's rent would normally be due when they moved in (and before they got the keys).

Check the property, nothing seemed stolen or damaged but she made a run for it in her car.

That's very normal.

Seems really normal...

Why would a listing agent do all the work for a buyer that a buyer's agent normally does? 

Sometimes your credit or the deal itself might change things so without knowing EVERYTHING about you (which would be hard to do in a public forum) it might be hard to really say what's "normal" for you.  

Outside of real estate, I enjoy classic cars and travelling with my family.Excited to learn and connect with you all!
