Cash flow implications of converting primary mortgaged residence to rental
The rental income is indeed taxable income, but you reduce the taxable portion of it by deducting expenses (including mortgage interest, maintenance, insurance, HOA, real estate tax, and of course depreciation). Due to the depreciation, you may end up breaking even, or having very little taxable income. Note that when you sell the property, your basis is reduced by the depreciation you were allowed to deduct (even if you haven't deducted it for whatever reason), and also the personal residence exclusion might no longer be applicable - i.e.: you'll have to pay capital gains tax. You will not be able to deduct a loss though if you sell now, so it may be better to depreciate it as a rental, rather then sell at a loss that won't affect your taxes. Also, consider the fact that the basis for the depreciation is not the basis you currently have in the property (because you're under water). You have to remember that when calculating the taxes. This is not a tax advice, and you should seek a professional help. "You are assuming 100% occupancy and 100% rent collection.  This is unrealistic.  You could get lucky and find that long term tenant with great credit that always pays their bills... but in reality that person usually buys a home they do not rent long term.  So you will need to be prepared for periods of no renters and periods of non payment.  The expenses here I would expect could wipe out more than you can make in ""profit"" based on your numbers. Have you checked to find out what the insurance on a rental property is?  I am guessing it will go up probably 200-500 a year possibly more depending on coverage.  You will need a different type of insurance for rental property. Have you checked with your mortgage provider to make sure that you can convert to a rental property?   Some mortgages (mine is one) restrict the use of the home from being a rental property.  You may be required to refinance your home which could cost you more, in addition if you are under water it will be hard to find a new financier willing to write that mortgage with anything like reasonable terms. You are correct you would be taking on a new expense in rental.  It is non deductible, and the IRS knows this well.   As Littleadv's answer stated you can deduct some expenses from your rental property. I am not sure that you will have a net wash or loss when you add those expenses.  If you do then you have a problem since you have a business losing money.  This does not even address the headaches that come with being a landlord. By my quick calculations if you want to break even your rental property should be about 2175/Month. This accounts for 80% occupancy and 80% rental payment.  If you get better than that you should make a bit of a profit... dont worry im sure the house will find a way to reclaim it." You have some of the math right, but are missing a few things. Here's what I can offer - if I leave anything out, someone please expand or clarify. Rental income can be reduced by mortgage interest and maintenance costs (as you mentioned), but also by property tax payments, association fees, insurance costs, landlord expenses, and depreciation. Note that if you don't live in the property for 3 years, you'll have to pay capital gains tax if/when you sell the house. You can live in it again for 2 of the last 5 years to avoid this. Many people recommend only assuming you will get 10 months of rental income a year, to account for transitions between tenants, difficult in finding new tenants, and the occasional deadbeat tenant. This also adds a buffer for unexpected problems you need to fix in the house. If you can't at least break even on 10 months of income a year, consider the risk. I think there are also some cases where you need to repay depreciation amounts that you have deducted, but I don't know the details. Renting out a house can be fun and profitable, but it's very far from a sure thing. I'd always recommend preparation and caution, and of course talking to professionals about the finances, accounting, and lease-writing. Good luck!
"All other factors being equal, owning your primary residence is almost always a good investment over the long haul. Why? Because you have to live somewhere, and rentals, especially long-term leases that are important when you have kids in school, etc.,  are generally in the same ballpark as a mortgage in most markets. Giving $1,500 to a landlord gets me 30 days of living somewhere. Giving $1,500 to the bank gets me a place to live and equity in an asset which requires maintenance, but always has intrinsic value.  Detroit is one extreme, Manhattan or Silicon Valley is another real estate extreme... everywhere else is somewhere in the middle. What isn't always a good investment is speculating in highly elastic ""investment property"" like vacation condos as an amateur. It's a cyclical market, but our attention spans are too short to realize that. As most of the other answers to this question indicate, people tend to be down in the dumps and see all of the problems with real estate when the market is not very good. Conversely people only see the upside and are oblivious to problems when the market is high." "Because the returns are not good. One of the big drivers in Australia is ""negative gearing"": if your investment loses money you can offset losses against your tax on other income. Institutional investors and corporations are in the business of making money: not losing it. Housing market investors are betting that these year to year revenue losses will ultimately be made up in a big capital gain: for which individuals get a huge tax break that is also not available to corporations. Capital gains are not guaranteed. Australia has benefited from 25+ years of economic, employment and wages growth: a result of good government planning, strong corporate governance and a fair slice of luck. If this were to end housing prices would plateau at best and crash at worst. A person who has negative cash flow investments has to sell them urgently if they lose their job. A glut of mortgagee sales and property prices could easily come off 20-30%. Rental yields on residential property in Sydney are about 4% with a capital gain of currently 10% but this has been flat or negative within the last 5 years and no doubt will be again within the next 5. Rental yields for residential property are constrained by mortgage rates: if it significantly cheaper to buy then to rent, why would anyone rent? In contrast, industrial and commercial property gets a yield of about 7% and gets exactly the same capital gain. This is because land is land and if the  price of industrial land doesn't grow at the same rate as the residential land next door eventually one will be converted into the other. Retail rentals are even higher. In addition commercial tenants are responsible for more outgoings and have fewer legal rights than residential tenants. Further, individual residential properties are horribly illiquid and have large transaction costs. While it is possible to bundle them up into property trusts so that units can be sold on the stock exchange it is far more common to do this with office and retail buildings. This is what companies like Westfield and AMP Capital do. Notwithstanding, heavily geared property trusts can get into deep water because of the illiquid nature of property as the failure of Centro  illustrates. That said, there are plenty of companies that develop residential houses and units for sale to owner occupiers or investors because that's where the money is." Here's how I think about money. There are only 3 categories / contexts (buckets) that my earned money falls into. Savings is my emergency fund. I keep 6 months of total expenses (expenses are anything in the consumption bucket). You can be as detailed as you want with this area but I tend to leave a fudge factor. In other words, if I estimate that I spend approximately $3,000 a month in consumption dollars then I'll save $3,500 times 6 in the bank. This money needs to be liquid. Some people use a HELOC, other people use their ROTH contributions. In any case, you need to put this money some place you can get access to it in case you go from accumulation (income exceed expenses) to decumulation mode (expenses exceed income). This money is distinct from consumption which I will cover in paragraph three. Investments are stocks, bonds, income producing real estate, small businesses, etc. These dollars require a strategy. The strategy can include some form of asset allocation but more importantly a timeline. These are the dollars that are working for you. Each dollar placed here will multiply over time. Once you put a dollar here it shouldn't be taken out unless there is some sort of catastrophe that your savings can't handle or your timeline has been achieved. Notice that rental real estate is included so liquidating stocks to purchase rental real estate is NOT considered removing investment dollars. Just reallocating based on your asset allocation. This bucket includes 401k's, IRAs, all tax-sheltered accounts, non-sheltered brokerage accounts, and rental real estate. In general your primary residence is not included in this bucket. Some people include the equity of their primary residence in the investment column but it can complicate the equation and I prefer to leave it out. The consumption bucket is the most important bucket and the one you spend the most time with. It requires a budget. This includes your $5 magazine and your $200 bottle of wine. Anything in this bucket is gone. You can recover a portion of it by selling it on ebay for $3 (these are earned dollars) but the original $5 is still considered spent. The reason your thought process in this area is distinct from the other two, the decisions made in this area will have the biggest impact on your personal finances. Warren Buffett was famous for skimping on haircuts because they are worth thousands of dollars down the road if they are invested instead. Remember this is a zero-sum game so every $1 not consumed is placed in one of the other buckets. Once your savings bucket is full every dollar not consumed is sent to investments. Remember to include everything that does not fit in the other two buckets. Most people forget their car insurance, life insurance, tax bill at the end of the year, accountant bill, etc. In conclusion, there are three buckets. Savings, which serve as your emergency bucket. This money should not be touched unless you switch from accumulation to decumulation. Investments, which are your dollars that are working for you over time. They require a strategy and a timeline. Consumption, which are your monthly expenses. These dollars keep you alive and contribute to your enjoyment. This is a short explanation of my use of money. It can get as complicated and detailed as you want it to be but as long as you tag your dollars correctly you'll be okay IMHO. HTH. "Look into the definition of ""primary residence"" for your jurisdiction(s). In some states, living in the home for 183 days qualifies it as your primary residence for the entire year." Two principles in comparing different scenarios:  1) keep the two scenarios as equal as possible in amount and timing of payments;  and 2) find the financial comparison at one particular point. So, your car loan, $10,000 for 35 months at 8% compounded monthly means you're paying $321.29 Suppose you make the switch and keep on paying the same, mortgage and $321.29 for the 35 months (see 1, above) Those extra payments, continued for 35 months at your mortgage rate of 5.59%, will pay off a mortgage of $10,354.10, which will more than pay off the $10,000 you added to the mortgage  In other words, making the switch will benefit you to the tune of 354.10 as of the day of the switch.  You could ask the mortgage company to give you the $10,000 and the $354.10, and all your payments and amortization would stay the same... (see 2 above) Of course, this is pretty much what Joe Taxpayer said... Danger. The affidavit is a legal document. Understand the risk of getting caught. If you are planning on using the condo to generate income the chances that you default on the loan are higher than an owner occupied property. That is why they demand more down payment (20%+) and charge a higher rate.  The document isn't about making sure you spend 183+ nights a year in the property, it is making sure that it isn't a business, and you aren't letting a 3rd party live in the property.  If you within the first year tell the mortgage company to send the bill to a new address, or you change how the property is insured, they will suspect that it is now a rental property.  What can they do? Undo the loan; ask for penalty fee; limit your ability to get a mortgage in the future; or a percentage of the profits How likely is it? The exact penalty will be in the packet of documents you receive. It will depend on which government agency is involved in the loan, and the lenders plan to sell it on the secondary market.  It can also depend on the program involved in the sale of the property. HUD and sister agencies lock out investors  during the initial selling period, They don't want somebody to represent themselves as homeowner, but is actually an investor. Note: some local governments are interested not just in non-investors but in properties being occupied. Therefore they may offer tax discounts to residents living in their homes. Then they will be looking at the number of nights that you occupy the house in a year. If they detect that you aren't really a resident living in the house, that has tax penalties. Suggestion: If you don't want to wait a year buy the condo and let the loan officer know what your plan is. You will have to meet the down payment and interest rate requirements for an investment property. Your question implies that you will have enough money to pay the required 20% down payment. Then when you are ready buy the bigger house and move in. If you try and buy the condo with a non-investment loan you will have to wait a year. If you try and pay cash now, and then get a home equity loan later you will have to admit it is a rental. And still have to meet the investor requirements. The fact that you are planning to sell the property does not make paying down the mortgage a bad idea. Reducing the principal immediately reduces the amount of interest you are paying every month. Run the numbers to see how much money that actually saves you over the time you expect to hold the loan. Don't do it.  I would sell one of my investment houses and use the equity to pay down your primary mortgage.  Then I would refinance my primary mortgage in order to lower the payments.
