Get the hardware off of amazon it’s way cheaper.

If it needs another breaker, they are readily available at the hardware store.From the tenant's description , it does sound like there is too much stuff on that one circuit. 

I do think there is some value to education, as long as you are not breaking your wallet.

I think people might get scared of having multiple of everything (4 bathrooms, 4 kitchens, 4 HVACs) that could break and need cap ex, but another way to look at it is that you're vacancy wallet is 1/4 as liable since the others can subsidize.

If the A/C quits in a way that is uneconomical to repair, a couple of hundred dollars at the hardware store or general store gets you some window units that will serve until you can replace the central air.If you just want to replace the furnace, the HVAC people will make noise about "the system will be unmatched", mostly because they want to sell you an A/C too, and a little bit because installing a new furnace with an old A/C can make the installation slightly more complicated. 

If you plan to put new blinds in this rental, or if you have similar blinds in your other rentals, maybe save some of the hardware from the broken blinds before you toss them - particularly the tilt rod (the long plastic thing you spin to tilt the slats), the plastic cones or pulls on the ends of the operating strings, and maybe the buttons or plugs on the bottom of the bottom bar that hold the lift strings to the bottom.When I bought my rental, it had blinds everywhere that were mostly in OK shape, but some of them were missing the above items, and I couldn't source them locally as individual parts. 

In my particular market of high end condo conversions we are looking for tech based units such as Nest and surround sound features, pot fillers and wine/beverage bars in kitchens, and heavy doors and more luxurious hardware throughout the house.You should do a tour of a lot of properties in the condos/homes in that area and you'll start to get a sense of the theme of what the consumer demands in your particular market. 

Otherwise, you're just going shopping without your wallet.

The second spreadsheet included previously omitted tasks such as investor hours and driving time between the rental properties and the hardware store and other locations pertinent to the management of the units.

The worst thing that could happen is contractors don't pick the best priced ,materials (excess expense), or they order too much material and they keep the extra material for another customer.If you have specific materials that you want to use, you can pick them out on the hardware stores website.
