Compare Renting Out a Spare Room Versus a Full Buy-to-Let

Renting a spare room and buying a second property to let both get filed under "property income" as if they are the same decision. They are not, in capital required, tax treatment, or how much hassle lands on you. This compares both against what you actually have to invest and what kind of landlord life you want.
