Fortunately the rules have been "modernized," which is kind of a rich NLP technique if you ask me. 

I'm finishing up an ADU garage conversion in Downtown Sac and plan to do medium term rental for travel nurses.

Modern is all dependent on the area.

Quote from @Yaroslav Shtogun: Hello Community,I am seeking advice on the following real estate situation:I’m in the process of purchasing a double lot property (100x100 in an RS-50 zone) that includes a 1,200 sqft wood-frame house and a 640 sqft detached garage.

The garage does have electric ran with a small meter base.

Late payments, property damage, and evictions are avoidable when you have a PM who knows how to find reliable renters.I encourage you to seek out a property management company that emphasizes tenant screening and uses modern tools for verification.

The house is a new construction in a Class C neighborhood.The tenants pay late rate ~50% of time, they damaged part of the garage, they have people not of the lease living there, and they leave trash in the yard.Part of me wants to keep these tenants because:-They do pay eventually-I don't want vacancy-The turnover costs could/will be high-How much more damage could they do?

I was told it's about $250 /sqft around $500k plus $50k for the garage(2car).   

Does it look like a modern-ish apartment with breezeways and internal stairs, or is it built like a roadside motel with long walk ways along the front.  

In today's competitive real estate market, having modern amenities can set your property apart, making it more attractive to a wider audience.
