However, the LLC will need to chip-in financially to help complete this renovation.My general question is what items should the LLC cover and which should my father cover for best tax benefits?  

I do estimates based on when I think major items will need to be replaced and how much they will cost and how big my portfolio is, etc.

That being said, here are a few other items that might be worth considering.

Without knowing exact numbers it is hard to have a firm opinion so I will present some items for you to think about. - upon sale, the property tax will be increased to be based off current market value (~1.1% of current value).

Tenant schedules directly and items get addressed quickly.

If Jesus came back and got into rentals NO, N-O-B-O-D-Y get's admin access into our system. 2) They want a standardized list for maintenance items so they know in advance what repairs would cost.Being a PMc I'd invite them to acquire any of the readily available construction estimating tools/software out there such as RSMeans, but would not take on such a task as building and maintaining such a database, honestly for any $, it's simply not what we do. 3) They want a copy of all invoices from contractors to us so they can verify we are not marking up more than promised.A-ok. 4) They want to be able to talk to our contractors before work is done (each time) so they can talk contractors down in price themselves.I'd be fine with this as long as they sign a waiver that they own any/all negative impacts that result from such including extended vacancy periods, vendor refusals of service necessitating there own self-search to secure amicable vendor etc etc.. 5) They mentioned that they pay around $300 for full paint in a 2-bedroom unit.... we do not have a contractor that will touch a full paint on a 2 bedroom for $300LMAO!

What other items am I missing?

You'll also need storage space for cleaning supplies, change of linens and towels and small miscellaneous items like a first aid kit, extra batteries, flashlights, broom, vacuum, etc.

I need it just often enough to send or receive items from vendors or local govt's to want the convenience of using it from my home, hotel room, or office.  

I dont think you can call it totally passive if someone does that they are probably going to make a mistake you need to work the loans and put time into them to ensure all the safety items you mentioned.2.
