I hope you haven’t paid them any money.

To defer all tax you must purchase in total at least as much as your net sale.

This is the BEST $100 you will ever spend, and if you listen to Amanda Han's tax book, you'll know it's also likely a business expense for you to write off :) https://biggerpockets.supercast.com/My perfect way to learn from the BP books is to listen to the audio book through the subscription above, then books that really stand out to me I go old school and get the physical copy so that I can re-read it, take notes in the margins, and put post it notes so key points are easier for me to re-reference in the future.

I 100% endorse adding in the escrows for taxes and insurance to set the buyer/borrower up for success. 

There are less taxes in Alberta too.

This is a self directed RRSP or TFSA account that allows you to lend your money out to people with the backing of their mortgage for a high interest rate. 1st, 2nd, 3rd mortgages, down payments, refinances, flipping or renovation money.

could be just like a regular deal, but if you're up for pitching, presenting and educating a seller on the tax and other advantages of seller financing, you just might turn it into a seller finance deal.

Same tax situation and more likely higher potential to appreciate faster.

If I can park the 388k ($415-27k) for one year at CD rate of 4.5% and then est 300k (after paying cap gain/depr recap) at 3.0% (assume CD rates lower) that interest income of about 24 months net of ordinary income tax is about the same as my current mortgage.Trying to play devil's advocate and think why selling this year does not make sense. 

@David R Pustelnik recommend you first focus on raising the rent for the first time in 10 years.By the way, how much have your property taxes and home insurance gone up since this tenant moved in?
