Annuals are at least $1000 a year, with insurance, taxes, and other costs you'd probably spend $8K a year to have it sit not flying. Add in flying costs and engine reserve you'd spend $10K or more a year.

Taxes for what exactly?

Insurance is about ~600 a year from what I gather.

So not sure how you go from 1k to 8k

When you have large assets, the gov makes sure to charge property tax.

Local tax of a few hundred up to $1k, $300 loan a month, insurance is more like $1200 depending on experience. Hangar and tie down fees...

Cant find anything on taxes on personal aircraft (past purchase of course).

Loan?

Hangers are indeed expensive depending on the area, but tie down fees are like $60 a month

Many states/counties have a property tax on airplanes. But compared to other costs (insurance, maintenance, fuel) it's a drop in the bucket.
