I live in Kashin, Tverskaya oblast, 145 km from Tver. Property taxes are based on value, I'm not sure how much because (good news) pensioners don't have to pay taxes on their home. A second property, you probably would pay taxes. Anyway, if you have to pay, its not a lot. Pensioner age I think now is 62 for women and 65 for men, ages used to be younger, but creeping up. We have a 2019 Subaru Forester and pay about 5-6k rubles a year for taxes, registration is negligible (I don't know).
If you don't mind my asking, where are you from and what will you be retiring from?
If you're going to be dumb, you better be tough...
