Alright so I have an elderly tenant who has bed bugs, is a moderate hoarder and who's rent is at least $150 under market.

These are for more mobile elderly.

With the 200-300k pay rent back to yourself for your elderly family member which should be enough to pay loan over next few years.

A quick google search and I learned it was the house of an elderly person who had been harassing neighbors (kids and adults walking by) for years.

When you come into my elderly parents NBHD I ask them to come inside and lock their door and NEVER open it for anyone whose identity they cannot confirm. 

Why would he let you cherry pick deals, he won't.You talk about "other wholesalers" not being ethical and being time wasters as near as I can tell you did the same,  Yes I read that you had an option where she could sell the house but as you said she was elderly and apparently she trusted you until numbers didn't add up in her mind.  

You have to understand not everyone is an entrepreneur.If they work and take a paycheck every week that is their mentality.Work until they can't and HOPE retirement and the government will take care of them in their elder years.Sadly that isn't going to be the case.

One in particular was from an elderly woman who owned it for 50 years.

Three didn't return my call and one is an elderly man who wants to unload at least one of his properties.

The elderly seller only has this property in the company and wants nothing to do with the management.
