Have had a couple of waterfront cottage lots for 50 years. Have sold one earlier in the year (100K cap gain) and now have an interested party for the other. Have a 40% marginal rate from other income and am not eligible to contribute to an RRSP. Other than trying to defer closing till following tax year, are there any other strategies to minimize tax in this scenario? It is also my understanding that property tax that’s been paid for past 50 years is not deductible or usable to increase ACB.
