DOM is creeping up, properties are sitting, and appraisals are not coming in where the borrower expected.

The seller must think he is sitting on a really hot property, or the buyer is asking for too long of a DD period.

Million dollar homes sit here, but there aren't very many houses in Amarillo that were built in 1921.  

Then I get guests who are thrilled to book a big 7-BR house for say, $600/night while competing properties sit empty. 

Those are spray and pray techniques that don't fit with sellers right now because sellers/owners are sitting on a very low rate and don't want to move to go up 4-5 points on their rate.Listings aren't a start now thing as well.

What you need to do is sit down and make a list of your 3 month, 6 month, 1 year, 3 year, 5 year, 10 year goals.

It has been sitting on the market for 186 days and the list price has been reduced multiple times.

I am willing to sit back and allow this to play out and evaluate the facts.

Sit down and hash out every detail and put it in writing.

If you can sit on the sidelines and be choosy this requirement is fine, but you are going to have to kiss a lot of frogs before you find someone with that much cash on a wrap sale transaction...it may take 6+ months unless you advertise like a mad man3.
