Potential profitability in the rental business varies greatly depending on the specific property, its location, and how attractive it is to renters. Ensuring the profitability of your rental property starts with a thorough evaluation of the property itself, any necessary renovations or foreseen future repairs, and how much similar properties in the area are rented out for. As long as you properly estimate and budget for all expenses and set rent above that amount, your investment should be lucrative. Consulting with an accountant or local real estate experts ahead of time can help.
