Sometimes software solutions have too high a learning curve for light weight use cases.

Be light on the policies.  

I usually don't allow them to do more than changing light bulbs and air filters.

I also provide light maid cleaning a couple times a month for common areas.  

Lots of free LED lighting, power saving power strips, discounts on insulation and even on heat pumps. 

What local factors best indicate no demand for rentals, what are the WARNING SIGNS?

i give them a list of what needs to be cleaned, since that can't be done up front, including sweeping garage, and sprucing yard, cleaning oven, blinds, ceiling fans, etc Also anything you see: Light bulbs burnt out, damage.stickers on doors, windows, blinds missing that were there, smoke detectors, etc. let them knw this is a pre-move out inspection and there may be things that happen ad lots of things you do not see.  

@Leon Lee without knowing anything about the property,  no one could give an acurrate answer.You are the one who can give the best response if $50,000 is enough to cover the inside finishes, such as kitchen, bath, carpet, cabinets, lighting fixtures, etc.I can tell you that on average, most condos are covered for between, $25,000-$100,000.

@Tyler Warne I would agree to let the tenant out of the lease, because you do not want to force that tenant into a situation they do not want to be in and they my very well just move anyway.

But I live in Aspen, CO so there are a lot of extensive remodeling projects around here where super fancy materials are left over- we bought 1000 sq ft flooring for $600, a Samsung stainless frig for $350, stainless like new dishwasher for $125; over the years we've gotten new bathroom fixtures & lighting, etc.
