You definitely want to charge enough for deposits and such to help cover cleaning and light damage repair but at the same time if you charge too much people will just bring their pets in and never tell you about it.

My main one is having someone come clean my house. 

I'm listing an older gulf access home in SE Cape Coral and it's booked solid with seasonal renters and its pretty dated, clean but older (actually my age, 49 :).

The $50/pet I charged initially was a one time fee to pay for carpet cleaning after they vacate.

Electrical needs complete replacement (wiring, electrical box) but the house has newer roof and appliances (heating and water heater are recent), and the plumbing looks recent, which is all surprising given the state of the rest of the house...It's basically a roof and a brick frame with appliances.

You will be doing electrical and plumbing and you’ll need to meet egress and fire / safety requirements.

We will take care of all guest communication, listing details, cleanings, scheduling of repairs, confirming bookings, stocking supplies.

If you're buying central you'll likely have to deal with 40-50 years old house (old plumbing, electrical, outdated floorplan, lower ceilings, 1-car or no garage, etc) that will generate higher repair bills during your ownership and higher property taxes.

We negotiated a bit on price so we were both still relatively happy.Make sure your inspector spends time on evaluating roofing, plumbing, electrical, etc.

I would also question the $500 for getting the unit cleaned up unless it was just completely rehabbed. $500 doesn't go very far.
