That’s crazy. My taxes are only about $1400 for a townhouse.
I have a huge yard all around the house, vaulted ceilings, enclosed Lanai, 2.5 car garage, huge gathering room which has kitchen+dining+living open concept. It is so quiet here, no noise from neighbors, no smokers in building, not hear dogs barking and no traffic noise. And we have a beautiful pool and gym for the subdivision. I am never going back to a condo or town house sharing walls with neighbors.
Also you are required to pay for building insurance and HOA.
I have neither. I dropped home insurance 4 years ago. You may be required to carry home insurance based on HOA rules.
