Or do they just want to sign an agreement to move out in 30 days and you'll give them their full deposit in cash on move-out day, if they leave the place clean?

As long as it cleans my bum I don't really spend a lot of time thinking about it, and I suspect most of your guests won't either.  

@Will ReedGet a second opinion from another company (one that just does cleaning and scoping not repairs as the companies that also do repairs tend to recommend repairs).

Furnishings that are easy to clean, along with amenities like high-speed internet and pet-friendly options, go a long way.

In the Parlor floor we added a large-ish kitchen with electric oven and cooktop that goes to the sub-panel that belongs to the Parlor floor, making it a nice 800ft 1 bedroom apt, with access to a shared backyard.   

If you do outsource, some management companies will cover various things like cleaning, supplies, etc. so look into that as well. 

We actually keep a pantry pretty well stocked with basics:  tea, coffee, cleaning supplies & laundry stuff, cup of noodles, ramen, soup, oatmeal packets, microwave popcorn, spices, bottled water, lemonade mix/crystal light, etc.
