We as a community tend to let things go because it "isn't worth the hassle" but this attitude is often responsible for the continuation of this kind of behavior and you would be providing a valuable community service. 

There are numerous national QI services and that is all they do and our fees typically cluster in a small range. 

I have had nothing but problems with applicants trying to apply and get screened.I don't particularly care about the auction aspect but it would be nice to have a modern website for applications to submit documentation and tenants to pay rent and sign leases.Anyone happen to know of any service like that?

Among many other issues, we found that instead of paying for a trash pickup service, the tenants had been storing all their trash in the barn on the same property.

Then there is the costs involved with getting it set on a foundation on a lot and hooked up to services.

How would I go about offering short-term rental owners my management services?

Then that being said you may guess that I would chose to find my own tenant and run a full background check on them myself and save the fees that your PM might charge for this service.

You might be better off just lowering the price till it sells for cash, but I have seen this option work as well.A thought that I had was that you might be able to find an auction service to sell the property. 

There are free services out there that will take care of all of your marketing for you, for free.
