Collected rent means exactly what @sable said, the percentage applies to money actually received in that month. If the tenant pays $850 of a $1,700 rent, the management fee that month is $85. Some agreements instead say "scheduled rent" or "rent due," which means the manager gets paid whether the tenant pays or not. Those two words change who carries the risk of a late tenant, so read which one your agreement uses.
The fees you listed are the normal three. Management fee, charged monthly, commonly 8 to 12 percent of rent. Leasing fee, charged when a new tenant is placed, often half a month to a full month of rent. Renewal fee, charged when an existing tenant signs on for another term, usually a flat couple of hundred dollars. A leasing fee should only apply to a new tenant. If the agreement doesn't say that in plain words, ask her to add it.
One line to look for that you haven't mentioned: the maintenance markup and the approval threshold. Many agreements let the manager spend up to a set amount, say $300 or $500, without calling you, and some add 10 percent on top of contractor invoices for coordinating the work. Neither is unusual, but on a house with a $1,700 rent, a $500 unattended threshold plus markup can eat a month of cash flow before you hear about it. Ask what the threshold is and whether invoices pass through at cost.
Also ask how long she holds the security deposit and under whose name, because deposit handling rules differ by state.
