How much more than my mortgage should I charge for rent?
As others have pointed out, you can't just pick a favorable number and rent for that amount. If you want to rent out your house, you must rent it for a value that a renter would agree to.  For example there is a house on my street that has been looking for renters for 3 years. They want $2,500 a month. This covers their mortgage, and a little bit more for taxes and repairs. It has never been rented once. Other homes in my neighborhood rent for around $1,000 a month. There is no value to a renter in renting a house that is $1,500 more then a similar house 2 doors down. Now what you can look at is cost mitigation. So I am using data from my area. Houses in my part of Florida must have A/C running in the wet months to keep the moisture from ruining the house. This can easily be $100 a month (usually more). The city requires you to have water service, even when not occupied, though the cost is very small. Same with waste, which is a flat fee: $20 a month. Yard watering is a must during the dry months (if you want to keep grass). Let's say that comes out to $50 a month, year round. Pest control is a must, especially if your house has wooden parts (like floors or a roof). Even modest pest control is $25 a month. Property taxes around $240 a month. Let's say your mortgage is around $1,000 a month. That means to sit empty your house would cost $1,435. Now if you were to rent the house, a lot of those costs could "go away" by becoming the tenants' responsibility. Your cost of the house sitting full would be $1,240. Let's pad that with 10% for repairs and go with $1,364. Now let's assume you can rent for $1,000 a month. Keep in mind all these rates are about right for my area but will change based on size and amenities.  Your choices are let the house sit empty for $1,435 a month or fill it and only "lose" $240 a month. Keep in mind that in both cases you will be gaining equity.  So what a lot of people do around here is rent out their houses and pay the $240 as an investment. For every $240 they pay, they get $1,000 in equity (well, interest and fees aside, but you get the point). It's not a money maker for them right now, but as they get older two things happen. That $240 a month "payment" pays off their mortgage, so they end up owning the house outright. Then that $240 a month payment turns to extra income. And at some point, their rental can be sold for (let's guess) $400,000. SO they paid $86,400 and got back $400,000. All the while they are building equity in their rental and in the home they are living in.  The important take away from this, is that it's not a source of income for the landlord as much as it is an investment. You will likely not be able to rent a house for more then a mortgage + costs + taxes, but it does make a good investment vehicle.
