We seldom find the Pro forma to be a real accurate picture.

Those houses will rent for maybe 2,500--$3K == NO CASH FLOW.Oh, you'd better check the c/o (Certificate of Occupancy) on this building--very seldom are basement apartments legal in Queens. 

Everyone has an opinion about legal protection, just like about dieting or economy.Here is the bad news.

I seldom get all 3.  

Cash flow is KING in the rental business and having even millions of dollars in appreciation won't buy you so much as a diet coke.

If you do use that rule, you will seldom find yourself in a bad position, unless of course there is that trend Nationwide mentioned where the rents are plummeting.

Literacy, diet, job training, personal financial counselling and addressing medial issues is all an aspect of responsible housing management.

The owner's intent to abandon a property is seldom expressed. 

This is the same as taking diet advice from someone 200 pounds overweight, it just doesn't make sense.It can be uncomfortable for people to see you succeed because it forces them to deal with their own inadequacies and failures.

You know, when I'm on a diet and keep getting junk mail coupons from Dominos pizza, I feel harassed as well... :-)Seriously though, I would consult an attorney, and verify what we all suspect (that you aren't breaking any laws unless you keep mailing after a homeowner requests that you stop).
