What's the catch in investing in real estate for rent?
Several, actually: Maintenance costs. As landlord, you are liable for maintaining the basic systems of the dwelling - structure, electrical, plumbing, HVAC. On top of that, you typically also have to maintain anything that comes with the space, so if you're including appliances like a W/D or fridge, if they crap out you could spend a months' rent or more replacing them. You are also required to keep the property up to city codes as far as groundskeeping unless you specifically assign those responsibilities to your tenant (and in some states you are not allowed to do so, and in many cases renters expect groundskeeping to come out of their rent one way or the other). Failure to do these things can put you in danger of giving your tenant a free out on the lease contract, and even expose you to civil and criminal penalties if you're running a real slum. Escrow payments. The combination of property tax and homeowner's insurance usually doubles the monthly housing payment over principal and interest, and that's if you got a mortgage for 20% down. Also, because this is not your primary residence, it's ineligible for Homestead Act exemptions (where available; states like Texas are considering extending Homestead exemptions to landlords, with the expectation it will trickle down to renters), however mortgage interest and state taxes do count as "rental expenses" and can be deducted on Schedule C as ordinary business expenses offsetting revenues. Income tax. The money you make in rent on this property is taxable as self-employment income tax; you're effectively running a sole proprietorship real-estate management company, so not only does any profit (you are allowed to deduct maintenance and administrative costs from the rent revenues) get added to whatever you make in salary at your day job, you're also liable for the full employee and employer portions of Medicare/Medicaid/SS taxes. You are, however, also allowed to depreciate the property over its expected life and deduct depreciation; the life of a house is pretty long, and if you depreciate more than the house's actual loss of value, you take a huge hit if/when you sell because any amount of the sale price above the depreciated price of the house is a capital gain (though, it can work to your advantage by depreciating the maximum allowable to reduce ordinary income, then paying lower capital gains rates on the sale).  Legal costs. The rental agreement typically has to be drafted by a lawyer in order to avoid things that can cause the entire contract to be thrown out (though there are boilerplate contracts available from state landlords' associations). This will cost you a few hundred dollars up front and to update it every few years. It is deductible as an ordinary expense. Advertising. Putting up a "For Rent" sign out front is typically just the tip of the iceberg. Online and print ads, an ad agency, these things cost money. It's deductible as an ordinary expense. Add this all up and you may end up losing money in the first year you rent the property, when legal, advertising, initial maintenance/purchases to get the place tenant-ready, etc are first spent; deduct it properly and it'll save you some taxes, but you better have the nest egg to cover these things on top of everything your lender will expect you to bring to closing (assuming you don't have $100k+ lying around to buy the house in cash).
