I brought over some lubricant, sprayed it on, and the key came out.

I would advise taking these with a grain of salt because some can overpromise, but if you ask them to show you the data behind the projections this can also be a way to accurately project what your returns will be.

When painters paint cabinets the correct way, they spray an enamel, both for looks and durability. at this point, and after getting everyone else's input, like Dan H says, I think you should just clean it up real good and re-rent it, it's looking like it's not worth it....

Your agent represents you and needs to know what's going on, and they can usually glean some extra details from the MLS and/or a phone call to a listing agent prior to making said offer, and advise you accordingly.Furthermore, no listing agent worth their salt is going to tell you, "sure...my buyer will accept an offer of X amount".

I love to hear about other investors in the Salt Lake area.

I'm not a lawyer, and I'm not in your state, so take this with a grain of salt but-If "accepted an offer" means that you signed a legally binding contract that doesn't provide you with an out, then the short answer is no, you cannot legally cancel the sale. 

I'll see your charts and raise you one more.If I were in Austin, Nashville, Salt Lake City, or Colorado Springs, I would be worried about the next two years.
