Should I offer to pay them for their consultation, or are these types of questions common as part of the PM vetting process and is a "courtesy service"?

Tenants should definitely not use common areas to store stuff or use the common area electrical.Document everything via email about notices, and just do everything politely and with respect.

For safety, perform immediate courtesy check-ins with neighbors and your PM, and enforce your lease criteria if the tenant falsified info.

Also consider if you would extend that courtesy to the buyer when you go to sell. 

We have a cleaner who does deep cleaning at the end of each month, and another who handles two hours of common area cleaning mid-month.

Quote from @Andrew Steffens: Great info on a commonly asked item! 

I have, at my sole discretion, waived the late fee as a one-time courtesy to a tenant whom (a) is in good standing and has paid promptly for at least a year, (b) has informed me in advance that the rent would be late, and (c) pays up within a few days after the late fee would have kicked in.Whenever rent is not received, I start right away with a rent demand letter and proceed with the eviction process on the first day it is permissible by statute, even if the tenant eventually pays (including collection costs). 

Keep it in your file.If the tenant later provides a new address and requests another copy, you can re-mail a copy of the same notice to the new address, but this is a courtesy copy, not a new or renewed notice under the statute.

Although, locking a loan is not that common in private money.Any lender asking for a deposit is trying to scam the client apart from a large commercial loan. 

One of the most common causes of residential fires starts in the kitchen — particularly from unattended cooking.
