Real Estate can be a good investment in times of inflation, and there has been some speculation that inflation may increase faster than usual over the next decade. But there is also risks associated with renting. You could have trouble finding a tenant when supply exceeds demand, or things could break down on you and cost a lot of maintenance.
An important factor in your decision should be the sale price vs actual value. If you think this offer is a really good deal, and you probably won't get a better one in 3 years (assuming value stays the same), then it may be a good idea to sell high while you can. But if you think you'll easily be able to get a similar offer later, then there's no real benefit to acting now, unless you hate being a landlord.

If you decide to take the money, you should find out how much the penalty will be to pay out your mortgage early. Also ask what paydown options you have, as most banks allow you to put down a certain percentage as a lump sum each year, and also increase your regular payment amount. And you can change to bi-weekly payments if you're not using them already. This way you avoid the fees while still accelerating the mortgage. You can probably find a spreadsheet or online calculator that can show you how much interest you will save from accelerating the paydown. Add to this any interest you could earn if the rest of the sale profits were put in GICs (for the sake of calculation). Compare this with how much interest you save by closing the mortgage now, minus the penalties.
