After closing sold a cellular tower lease that generated $790,000 in cash reducing our acquisition price down to ~$56.00 per SF What made you interested in investing in this type of deal?

He finds a telephone.

One month I put up 1000 hand written bandit signs after hours of cutting up signs and writing we buy houses, driving around cities placing them on telephone poles and calls from the city threatening to fine me.

All applicants should directly contact you through your telephone number or voicemail, not through the zillow account that could be shut down at any time without notice, discussion or reason.  

It may not be as easy as it sounds , your neighbor is a General Contractor , thats good , you do realize his main tool is his telephone and his subcontractors .

Buy a fax card or machine and add that to my telephone line?

I would call every "handyman special" sign you see hanging on telephone polls in your market.  

In the event that you do have a true squatter its a fairly standard eviction process which is unfortunate but does happen in this business.On a preventative note if you have a vacant unit you can put in a security system that uses cellular and you will get notification if anyone comes in.
