You'll see some familiar names thrown around a lot: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend you search for each app online and see what they offer, how much they charge, etc.

Fees can be sneaky—markups on maintenance, random charges for inspections, lease renewals, etc.

Is your DSCR ratio greater than 1-meaning are you cash flowing (according to the lender's criteria of mortgage, property taxes and insurance (and HOA) if applicable).

Sometimes I'll tell them not to fix it (a punch hole in the wall) and I'm charging them for it.

Generally, most reputable lenders in this space won't have any significant surprises with terms and fees because they spell them out upfront in the applications that they provide before you move forward with the loan underwriting.5. 

This includes all charges paid, utility accounts set up, renter's insurance established, lease signed, etc.

If you present the listing well, put it on multiple platforms and are asking a reasonable rent you will get plenty of interest and applications quickly. 

Do you think we shouldn't charge that?

You will want to understand taxes and applicable laws.

Most property managers don't charge any markup.
