I completely understand that the Costa del Sol carries significant weight in global tourism and international investments.

If it is block construction the engineers will make you beef up the slab and add piles to support the new weight of the second floor.

Hi All, I have been interested in storage sheds or quite some time.

If you can’t quantify risk and don’t understand the mechanics of “weighted” average of expected return and range of returns (standard deviation) then you are at a severe disadvantage and should consider a competent investment / financial manager for your investment capital.  

After weighting all of that, does it make the most sense to try to keep this tenant in place? 

yep your weight in gold.  

I would be happy to have them move the large storage shed and its whatever contractor provides an acceptable bid rather than city employees doing the work.

They may or may not have good reasons and unless they communicate those reasons and perhaps even substantiate them I really try not to give them any weight.

Check bed frames and chairs for their weight limits. 

I find with ANY project on a property, PLANS are worth their weight in gold bc they will show the exact inches, ft, etc that the project entails.
