If you google me or my business Remodeling Solutions, you can easily find my cell for a text. 

If all goes to plan I'll collect until I'm 85, if my cancer gets worse I'll try to sell the note while I'm above ground to prevent my wife from having to deal with it.That's a long answer to a short question but NO, I don't consider 20% to be too low, depending on conditions.

I think @BOB CRANEY hit the nail on the head  its the area .. my folks i deal with in these areas.. fico is not a criteria.. its do they pay their cell on time.. are they felons.... you have to triage the bad credit or sell the house. 600 up probably does not want to live in that area. 

Once you complete the class they provide your cell number to local titles companies that then offer closings to the next notary on their list.

I used to work with my dad for beer money when I was younger and took over for a while after he got sick and eventually passed away from cancer.

The other ideas I have is to (1) get cell towers for the building as its taller than the surrounding buildings and has great line-of-site (2) offer signage to either billboard companies for the roof or on the side of the building.If you have experience or information on courting cell companies, billboard companies and what they may add to the property bottom-line, please chime in! 

Now does the owner run their cell phones through the business?

There are no beds, or TV  I use the computer to research properties, check email and enter details in my excel that has property information  I may play some free cell from tome to time   

I keep thinking about Steve Jobs and how much would he have given to be able to cure his Pancreatic Cancer as he was a multi-billionaire.The good thing is that we will survive and learn from this lesson.

Message me for his cell phone or you can find the business number online.
