Living in New England, I don't see a need to store water since we have so many streams, ponds, lakes everywhere and I can just filter.

It increases risk, not just to the revenue stream, but to tenant damage.

Families down south still impacted by the BP oil spill?

It will never have the luster of SF, but remains a % proxy on the nicer areas because people that get priced out of the prime areas spill over into the secondary and tertiary markets where they can still commute reasonably to work.

I have had problems with renters in "good" areas and bad but it's a great trade off for me to stay in the below 30-40k markets and have more streams of rental incomes.

My goal, as always, is to create a new income stream by installing carports AND ideally the income stream would be independent of my tenants.

The prospect of steady and continuous income stream is very tempting, but I feel new investors are making a horrible mistake by jumping into long term rentals with leverage.  

You can pick up a great clean 10% lien at readyprop.com for Under 5k to start your residual cashflow stream Best of luck on your RE journey :)

This allows a nice passive income stream when not utilizing the property.  

There will be a very large revenue stream created once recreational laws are implemented in Portland.
