First off, you should determine market rent. Is it $1,100? Or is that a number you see advertised but can't really prove that is what your property is worth?
Second, Zillow estimates of value are worthless. Often they are off by 30 percent or more. If this is a house in a tract neighborhood or a condo in a large project, comparable sales should be easy to find. Call the agent that sold you the property or another agent that actively lists and sells homes in the neighborhood. Get current comparable sales and rental information.
Third, what are your loan payments? Did you finance $200k and paid it down? Or did you finance $150k when you bought it? Interest expense is interesting, but you are interested in cash flow.
Bottom line is that a property that would cost $140,000, produce $950-$1100 in market rent and have $300 in HOA fees BEFORE expenses (vacancy and collection loss, repairs and maintenance, taxes and insurance) is a poor long term cash flow investment. However, if property values in the neighborhood are increasing 5 percent per month right now, holding onto it for a year might make sense as a speculative move.
