What are the advantages and disadvantages of leasing out a property or part of a property (such as a basement apartment)?
The obvious advantage is turning your biggest liability into an income-generating asset. The downside are: (1), you have to find tenants (postings, time to show the place, credit/background check, and etc) (2), you have to deal with tenants (collection of rent, repairs of things that broke by itself, complaints from neighbors, termination, and etc) (3), you have to deal with the repairs In many ways, it's no different from running another (small) business, so it all boils down to how much time you are willing to invest and how handy you are in doing reno's and/or small repairs around the house. For profitability/ROI analysis, you want to assume collection of 11 months of rent per year (i.e. assume tenant doesn't renew after year, so you have the worst case scenario) and factor in all the associated expense (be honest).  Renting out a second property is a bit tricky as you often have to deal with a large operating expense (i.e. mortgage), and renting a basement apartment is not bad financially and you will have to get used to have "strangers" downstairs.
