Have an Inspector who you will work with regularly. 

For the wall cleaning, TSP concentrate works well.

The property is just in horrible shape and I want to clean it up and use it for agricultural purposes.

--Utilities, guest communication, cleaning, furnishing, stocking staples, quality control as a start, there's a lot!

I'd go clean it up if it was my fault but this tenant has been there over a year and suddenly there are bedbugs so she's the cause.  

We did that regularly here for short sales. 

I had told the seller this information and they are really trying to get rid of this property.The property is not in terrible condition at all, it needs minor repairs and a good clean up.

Let me know if you have any suggestions for good cities to start investing, that are safe, clean and have reasonable property prices!

Interest income is always taxed at regular income tax rates. 

Yep, if it's running and not cooling it probably needs to be cleaned.
