As an improvement on this technology, we have a test installation using electric resistance thermal storage units ... essentially larger baseboards filled with bricks as a thermal mass.  

I still have some of my things in storage at the house, but haven't really missed it, and probably will not be going back to get it. 

The OP would still have a 30 usg storage heater, but the recovery rate would be dismal - depending upon the element that is out, it could be less than half of normal.We have 60usg storage tanks in two of our student rentals - same tank, with the same standby-loss, but one has an optional third element.  

One would have to have grade A stock I would think to pull this off and make it financially feasible for the sellers.

Does this sound like a feasible and effective plan?

With as cheap as storage is these days, either locally on an external hard drive or even better in the cloud, there's not a big reason you can't keep the records for years.

What I mean is that in this current deed, the owner has the one property listed as 'storage' because it is not habitable by tenants.

This is not a topic that I hear about a lot, but Ive been sent Marina for sale:-holds 75 boats-pavilion area-huge garage (steel bldg. presumably for winter heated storage for boats)-large fenced in storage area-asking $160kI am honestly wondering about the liability aspect of the water, does anyone have experience with this? 

If you pass your feasibility cutoff and aren't protected with a good finance contingency your earnest money is at risk which can be as much as 1% of the purchase price.Little more to it than fresh debt but it can be worth it if you get a good price and the interest rate works.Just know what you are getting yourself into but it can be a good thing.

I use them for all of my file scrubbing, storage, and recording needs so I will try them for my next O&E report.
