Sounds like you have a bit of a messy situation, so you may find it hard for someone to say "yes" to helping you out.

The bedrooms were in decent shape but everything needed carpet and paint.

So one of the units is empty and has carpeting that’s very bad.

Over 9 years, we replaced carpet with hardwood, installed all new fixtures, re-tiled bathrooms, painted inside & out, all that good stuff.

Probate takes a while and it can get messy.

Buy a carpet shampooer and use it. 

We have quartz countertops, bifold aluminum doors (4 large open doors), beautiful new kitchen with crown molding cabinets, waterfall kitchen island, ancient stone wall in our living room, all hardwood floors, etc. they are comparing my house to houses with carpet, old cabinets/kitchen, etc.

For my rentals hardwood floors simply because they are easier to clean and maintain, longer durability than carpets. 

I ask because I'm hoping to become a CPA after I graduate and looking for some material to reference.Doesn't adding all these personal items make the depreciation schedule long and messy?

We pulled carpet, sucked up water, started fans.
