If you are or are planning to buy, renovate and sell homes on a regular basis, then yes, it would be considered business income.
If you are going to enter the sale as capital gains, then since your partner is not a spouse, you would have to divide the amounts yourself, then enter them into TurboTax.
Outlays and expenses are the amounts that you incurred to sell a capital property. These types of expenses include fixing-up expenses, finders' fees, commissions, brokers' fees, surveyors' fees, legal fees, transfer taxes, and advertising costs.
Costs to improve or add to the property would go into the Adjusted cost base. Adjusted cost base would also include the cost of a property plus any expenses to acquire it, such as commissions and legal fees.
