I went to School in Louisiana to get my Captains Licenses and worked out of all those ports in Texas running Crew boats and some Supply boats, until I joined the Union and sailed on oil tankers.

For this reason, if a tenant calls due to a malfunction of the smoke detectors and a technician is dispatched, you can have the following outcomes:Technician determines the smoke detectors were faulty, and replaces - owner chargeTechnician determined the smoke detectors batteries needed replacing - tenant chargeIf written into the lease that the tenant is responsible for such replacement and the detector was easily reachable, - if not or if the tenant is elderly or disabled, assume reasonable accommodation: owner charge=time/labor & tenant charge=battery costWhere the property manager must be mindful is in the allocation of the owner's resources (money).

MF close to the university is especially in demand as there is a built in supply renters. 

It's up to you if you want the tenants to provide the supplies or if you want to pay for them and add it to the rent.

I see lots of these people have website claiming they can supply properties at 30%, 40%, or more discount.

Maybe even give them a detailed cleaning list, and drop off the supplies so they can have it ready for showings? 

You will need to supply the lockbox (can buy at home depot).

Doing the work yourself will take longer, you won't be able to buy supplies at contractor discounts, and the longer you take to get the work done the longer you have carrying costs without rent money to cover it.

I guess its time to dig up the door to the Y2K bunker in the backyard and update the supplies and the ventilation systemCome to think of it maybe it wouldn't be good to survive and stick your head out to a wasteland.

You can attend your local county auction, and watch to see who is buying properties (these are people with cash money), and approach them to see if they would be interested in having you supply them with properties in the neighborhoods they buy in.
