@Johann Jells Thabks again, it turns out it was the heat exchanger between the boiler and the storage tank.

The stats are: -5 stories totaling 20,000 square feet above ground, plus a full basement which is partial commercial space and partial tenant storage/utilities-First floor commercial space is around 2300 square feet with an additional 1500 in the basement, 12' ceilings in the first floor-14 residential units above, most have private balconies or decks, elevator, bike storage, mail room.

Around 25 years ago, I knew someone who owned a building (shed), a few mini storage units on a lot in a town.

My thought would be that you could probably buy a smaller mini or maxi storage facility and self-manage it. 

., My original quote for this thread was up to $600k, that was my highest bid when I was trying to have a 4 family built in the style of All Brick with each unit running 1000 sqft [became to small for a 3x2 for what I wanted], for 4000sqft total size on a full basement used for garage space and storage.

This is a triplex with an option to also rent out the garage for storage.

The outbuildings will not be used for vehicle storage or any storage for that matter until I replace the roofs.

Why not look into buying a storage or some mini-mall.

For the state of Colorado, I want to pull the tax records to see some of the Self Storage tax records.

If you know any (or are yourself) large apartment, self storage, mobile home park, etc. syndicators in the Bay Area and Los Angeles area, please reach out to me as I'd love to go out for coffee and learn more about you and your firm.Cheers all, and hope to meet you.Andrey
