Buying a multi-family home to rent part and live in the rest
Think carefully about the added expenses.  It may still make sense, but it probably won't be as cheap as you are thinking.  In addition to the mortgage and property taxes, there is also insurance and building maintenance and repairs. Appliances, carpets, and roofs need to be replaced periodically.  Depending on the area of the country there is lawn maintenance and now removal. You need to make sure you can cover the expenses if you are without a tenant for 6 months or longer.  When tenants change, there is usually some cleaning and painting that needs to be done. You can deduct the mortgage interest and property taxes on your part of the building.  You need to claim any rent as income, but can deduct the other part of the mortgage interest and taxes as an expense.  You can also deduct building maintenance and repairs on the rental portion of the building.  Some improvements need to be depreciated over time (5-27 years).  You also need to depreciate the cost of the rental portion of the building.  This basically means that you get a deduction each year, but lower the cost basis of the building so you owe more capital gains taxes when you sell. If you do this, I would get a professional to do your taxes at least the first year.  Its not hard once you see it done, but there are a lot of details and complications that you want to get right.
