I am that guy in the comments that calls these people out.

Here is my experience, I once sent out 5,000 beautifully designed, professionally printed post cards and got zero calls.

People don't read STR descriptions you see this alot with international properties where people expect US standards.

There are plenty of entry roles from cold calling, scrubbing data and find deals for investors, leasing assistant, work on construction sites, office admin, project coordinator, Title assistant, RE photographer, transaction coordinator.. on and on. 

They could also call the local board of realtors and talk to the grievance or professional standards dept to file a complaint.

In that case, get the seller to call.

Just call up an agent and ask them if they are the best in their market , odds are the first call you make will be the one .

No problems with rust but do have to deal with hard water; they have a chemical treatment called a pillow that takes care of that.

As a MF agent who spends a large amount of time calling apartment owners (or rather, numbers purporting to be apartment owners), please believe me that reaching out to random run down buildings owners is unlikely to get you any deals.

Here's their page called My Lodge Tax, for STRs. https://www.avalara.com/mylodgetax/en/index.html Process returns, Save time and hassle.
