A Pitts like all aircraft.
Professionally maintained c of a machine hangared at a regional airport ~ 10K before you put your fuel in.
A permit machine maintained maintained by you/ friends etc. hangared at a small strip ~ 2.5K before you put the fuel in.
This assumes the aircraft needs nothing, have some spare cash they rarely need nothing!
Would probably help if you tell us what you have budgeted for! then we can give more generalisations and opinions on what you have not!
Have fun
