Most attorneys demand unreasonable detainers and even when you pay the highest fees it is often difficult to talk to your own attorney when you want to ask simple questions.

Depends on the market you are in, but that doesn't seem too unreasonable.

Given that, I don't think it's unreasonable to tell prospective tenants that you'll consider it but you aren't going to fix items you consider nitpicking and let them decide if they want to spend the time on it.

I'll try to lay out my "annoyances" with them and would appreciate any input just to make sure I'm not unreasonable.1.

I personally think that it is unreasonable to charge people to seal up holes from pictures. 

It's not unreasonable for her to at least ask.

I don't think it's unreasonable to see a 20-30% in some markets potentially more in certain specific areas.

I think that no, that is not unreasonable. 

Some of the things you're missing are: you have no property management fees (always assume for 10%, even if you're going to self-manage), you have an unreasonable interest rate (lowest I know my clients are getting right now is about 6% or 6.5%, so I'd put at least 7% for yours), you have no water expenses (Cleveland the owner pays water unless they bill it to the tenants at a flat rate every month, or get reimbursed), and your taxes seem low (use: https://fiscalofficer.cuyahoga... and assume that the property will be reassessed at market value upon purchase).

@Aubrey BuikemaThe tenant's request for you to pay for 5 nights of a hotel is not only unreasonable but her story also does not make sense.
