What are the basics of apartment rental finances?
Well for starters you want to rent it for more than the apartment costs you.  Aside from mortgage you have insurance, and maintenance costs.  If you are going to have a long term rental property you need to make a profit, or at a bare minimum break even.  Personally I would not like the break even option because there are unexpected costs that turn break even into a severe loss. Basically the way I would calculate the minimum rent for an apartment I owned would be: (Payment + (taxes/12) + (other costs you provide) + (Expected annual maintenance costs)) * 100% + % of profit I want to make. This is a business arrangement.  Unless you are recouping some of your losses in another manner then it is bad business to maintain a business relationship that is costing you money.  The only thing that may be worth considering is what comparable rentals go for in your area.  You may be forced to take a loss if the rental market in your area is depressed.  But I suspect that right now your condo is renting at a steal of a rate.  I would also suspect that the number you get from the above formula falls pretty close to what the going rate in your area is.
