Operating Expenses:Consider all the costs of running a B&B and event venue—staffing, cleaning, maintenance, utilities, insurance, marketing, and supplies.

I have clients at my W2 who didn't do this and are now paying environmental remediation companies (like the one I work at) hundreds of thousands to clean it up, by order of the EPA, even though the PREVIOUS owner caused the issue.

How do you know your ownership is clean?

What you've shown here is not really a cause for concern in my eyes, however I see much worst conditions regularly.

I'd focus on getting a better property manager, their job is to shield you from most of these headaches and to prevent them in the first place through tenant selection and doing regular property inspections.

Property Management Company we work with right now to manage is fine with regular rental but I am having hard time working with them on student rental where some of the regular renting rules don't generally apply. 

But you may be right that it's a little too sloppy and could be cleaned up a little for ease of reading. 

Begin small by making regular contributions to build your portfolio over time.

For clients you bill regularly, you can schedule invoices to send automatically, so you don’t have to do it manually every time.

If after adding the additional monthly recurring costs (electricity, gas, water, internet, insurance, lawn care, snow plowing, etc.) to the standard long-term costs (Mortgage, taxes, regular insurance, etc.) the property won't net at least $100 if I can get the average rent I see on FF for that area, then the property isn't worth more investigation.
