.), with as little renovations/improvements as possible since we need to move in immediately once we arrive and it would not be feasible to find somebody to fix the place without supervision.So the question is: how do I find the best way to finance 100% of my home's value?

Complete rehab properties may not be feasible unless you go with the FHA 203k loan option which can be tedious.

One is a row of 5 garages, the other is a row of 4 storage units.

Whether its a storage complex, 16 unit Multi, 31 unit fully lease boat storage complex...etc.

Is this a feasible and sound strategy?

Make it known that there is zero tolerance for non-building residents to use the facilities.If the Unit provides "additional storage" like say a 3 car garage, or some sort of barn/shed outside of the building, monetize it.

They can save 20% or more this way.We are also evaluating electric resistance thermal storage heaters at one property - these look like oversized baseboards and are filled with a thermal mass (bricks).  

That sounds like a feasible route for me to take.

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.
