Two grand to change tenants! Good grief. Doesn't cost me anything like that much (assuming only a few days empty).
I use an agent to advertise, find and screen potential tenants, then sorting out the financials and legals.
An agents will typically change about 12% as a fee for the work.
On top of that I get an industrial clean done of the property and often redecoration and re-carpeting.
Plus the void periods and so on
So it's a minimum of a grand a time, and often a lot more
