Would you sell a leveraged position in an individual stock that appreciated 100% in the last 4 years?
I don't know what is your leverage but it could be as high as 20x (5% downpayment).
This is your current situation. No diversification, tiny profit, all in the hopes that it'll climb more. This is greed. Past performance doesn't guarantee future performance, take advantage of all this craziness of covid and almost zero interest rates.
Consider this:
- $18,600 / $450,000 = around 4.1% return, gross, before property taxes, maintenance, possible vacancy, utilities, property management (even if you do it yourself). Add interest payments on top of it.
- You don't plan to move for another 10years. It's not a given that you'll want to move to your current rental. Life happens, you might have reasons to move somewhere else. If you decide to move at all.
- Interest rates are as low as they can possibly be, they're going up in March, and then several more times this year. The higher interest rates, the lower real estate prices (fewer people can afford higher mortgages).
I would sell now, pay taxes on it and max out TFSA/RRSP. If you put money in RRSP, then you might pay a really low amount in taxes. Absolutely no need to gamble the system.
You'll have diversification and flexibility. No greed, no risks, just common sense investing.
