A little internet research has gotten me the phone number of the likely owner. 

Around here a lot of the homeowners that end up actually selling to investors are older people who don't really utilize the internet much.

I know which is very high, my property is listed as non residential as per water company since meter is 8in, currently I am paying as a landlord full monthly water bill and all my profits this bill is eating.I ask the water company my property has submeters if i make those active is the water bill going to reduce by making the property as residential?

These would be things like business mileage on your personal vehicle, a home office, maybe your cell phone and internet, etc. 

Can they report me for non payment to CBs or will this stand as a disputed amount?

Recourse or non-recourse loan?

I have over five rented cash flowing single family houses and was wondering if anyone knew of a lender that would lend on it with terms of 30 year amortization, under around 5%, and non recourse. 

Yes, I will keep you posted.Hey LavetteSprout is a "Non-QM" lender, not an intermediary. 

Internet strangers from all over the country may have opinions, but few real answers.

I personally advocate using paid traffic for means of canceling leads.Many will argue motivated sellers aren't on the internet looking due to the fact of their age.
