My question is for an 870' condo, built in 1968, no pool or amenities, is it fair to calculate 5% for maintenance?

However, she has fallen in this habitual routine of paying at the end of the month.

This is a great example of how "saving" a little money by neglecting maintenance can cost you much more in the long run.

Cuts your potential maintenance and cap ex expense exposure. 

If you're hiring out the management to a large professional hosting company, who are responsible for the maintenance on the property, wouldn't that place the majority of liability claims against them rather than the property owner?

Beyond the Monthly Management, Placement & Maintenance fees, all other fees in our contract are IF EVENT -> THEN fees.

Your maintenance budget, assuming nothing else goes wrong in 2 years, covers a $4,100 turnover cost.  

We give back with scouting and Vet stuff but still kinda finding a routine and hobbies.

I have a couple of commercial real estate properties, but have it written into the lease that the tenant is responsible for all repairs and maintenance.
