Business with "friends"

So a year ago we (my husband) made a deal with a guy from his work for our living arrangements when we moved to Florida. The deal was simple so that neither of us lost equity in our homes and so that financially it was easier for all parties involved. They were moving to NM the same time we were moving to FL so we were just going to switch houses and pay the utilities while continuing to pay our own mortgages.
Sounds like a great deal. Two friends helping each other out.. And now, months into this agreement, they have decided that it just doesn't work for them anymore. They have 'outgrown' the arrangement and now would like to live on base. We did not hear this from them, it was second hand from people in NM who thought WE KNEW! After talking to them and squeezing the truth out, we found out this was true and would have to put our house up for sale AGAIN (we took it off the market so that they could live there).
So now putting it on the market again has had its own snags. Between them not making meeting set up with the relator and making this whole thing difficult its been a rollercoaster.

Now for the newest part... Our relator finally met with them and told them that before they go on their vacation that they HAD to make it show ready and clean up. She was there today, and alas, the house is trashed. She sent me pics... Apparently this is SHOW READY... I have never wanted a beer so bad.
I am so happy i get to deal with this 7 months pregnant and all by myself... Nice "Friends"
