The level of competiton in the industry is unprecedented, even my 79yr old grandmother has noticed the massive influx of SS facilities. 

CoStar is also tracking more than 20 large electric vehicle, battery, and semiconductor plants planning to open across the U.S. during 2024-26, and suppliers to these facilities will likely generate millions of square feet of additional leasing over that period.Here are several graphs illustrating the current national commercial industrial market in The United States of America:Here is the full USA industrial market report for you to review: https://d2saw6je89goi1.cloudfront.net/uploads/digital_asset/file/1170835/United_States-Industrial-National-2023-10-02_compressed.pdf Data includes: Sale price per unit distribution, cap rate distribution, cumulative sales volume by year, months to sale, recent significant sales, vacancy rates, market rent per square foot, construction deliveries/demolitions, economy, job growth. population growth, and Los Angeles county sub-market activity.

Forgot maintenance on facilities or security systems. 8.  

Check local laws-I’m my state in Australia the landlord must provide facilities to dry clothing be that a cloths line or a dryer but they don’t need to provide a washing machine, seems weird but there it is.The catch 22 is that if you as the land lord provide it then you must maintain it- no good deed goes in punished after all.That said, you  can put terms in the lease that IF and additional appliance breaks you won’t replace it, as long as there is mutual agreement in the agreement at the onset. 

Just got back from the Afgharristan in March, so I'm still adjusting to cooking my own meals. 

If it is medical personel, then I would think you want to be in an area with multiple hospitals or facilities like UTSW/Parkland/Scottish Rite/Children's area in Dallas.   

Their kitchen is directly beneath mine and whenever they cook, their cooking odors travel up and become overwhelming in my unit.
