Can you consider storage as a small, supplemental revenue stream?

This makes buyers pay 20 cents on the dollar for the future income stream.

Needless to say, I'm exploring multiple revenue streams.

I know you can't take cash out with a stream line refi, but I do not know for sure if they base payments on the original principal amount (resulting in less than 30 year mortgage) or the principal due at time of refi.  

I have a goal of getting into real estate (buy and hold multi-family) to diversify income stream.

Watch the movie PACIFIC HEIGHTS to find your answer!

As a result, I am looking to parlay the income I do make from it and put it into more passive means of generating wealthI run my own businesses as well and, though my revenue streams are not quite that volatile, I too am dependant on the business cycles of my clients.  

Watch movie "The Secret" watch for Esther Hicks, Will Smith, Oprah and Rhonda Brine author of the Secret, her follow up book "The Power" is considerably better.

For the HVAC it is a hot water/stream baseboard, and the units have wall A/C units in them (so tenant pays for usage of them with electricity).

You're able to add text with either which is important to me, and they are responsive.Even windows live movie maker works well (transitions, effects, text, sound track) and is likely already on your computer unless you have a Mac.
