"My" felon was a nice guy; his supervisors at work spoke so highly of him they provided him with furniture, pots and pans, silverware, even a TV for the rental as he had none of these when he moved in. 

Another idea is a move in basket of hand soap, paper towels, and toilet paper.

A tenant had a water bill 5X the usual due to a leaky toilet.

Keep all lavatories, sinks, toilets, and all other water and plumbing apparatus in good order and repair and shall use same only for the purposes for which they were constructed.

But as you said the entire situation could be very stressful and take a long time to pan out.

I explained that (1) This should have been something adequately documented in the Roofstock diligence vault prior to any offers being made, whether the faucets, shower heads, and toilets were up to code due to the local statutes requiring the certificate of compliance. (2) Irrespective of that not being done, I need to know if the management company will actually handle it for us after the fact because I still had not heard back from them.

Buy bulk on items you know will need, like toilet flaps, control values for toilet, even look for used snake for drains on craigslist.

Recently I had a plumber come because he complained the toilet was making a strange sound.

I would guess any duplex in Milwaukee for $28k these days will need a lot of work to get back into good shape [easily $10k, possibly much more] and I would not want to rent to tenants who are willing to live in a bad property that leaks - expect to see more damage from these tenants - expect to get calls about water leaks, broken toilets, broken windows, high heat bills, water heater issues, furnace issues, ceilings bulging due to water leaks, possibly ceilings falling down [happened in the last two weeks to me], and potential fires [property across the street caught on fire and tenants left] and so on. 

Construction materials cost like redwood, paint $46/gallon, faucet, even toilet cost have really moved up in price.
