My wife is an artist /interior decorator too and makes beautiful spaces on a budget, so would kill it with MTR, I think. 

Now, each lease will be unique, so you can't apply this across all commercial leases, but commonly, LL is responsible for exterior and structural components, while tenant is reponsible for any interior items.How to best explain this: honestly, I would request the tenants have their own legal counsel review their respective leases.  

That's about what my major renovation cost (new electrical, plumbing, new exterior and interior paint) in 2022 but I bought  in-stock cabinet, light fixtures and faucet fixtures myself.  

The addition of a private balcony and standout interior design further elevated its appeal to both short-term and long-term tenants.

We have added new interior features and a new roof.

Also, if I found a 4/4 in the right area for the right price, I would still want to close up any living and/or dining areas and any interior community areas.

But I recently upgraded and used a local designer who has given me full sets of interior colors and exterior colors so we can properly design each home

You will likely have common area lighting (interior and exterior), perhaps heating and cooling too. 

I have a background in interior design and have a real estate company.

In addition, several items can be done simultaneously (I highly recommend this to save time as time is your enemy) such as doing the exterior siding or stucco at the same time interior rough electrical and plumbing is going on.Foundation is always first and rough framing follows that (which includes windows and exterior doors).
