Any successful Landlords on here??

Here's where I'm at with my rental property. We have been landlords for almost 3 years. The neighborhood was going south, we had some family issues, and couldnt pass up the house we have now. Also we bought back in 04 with the intentions of flipping the house in a couple years, wrong!
At first every month something needed to be repaired, mostly minor stuff but now I have to drive over, fix it and then be told about something else they forgot to tell me about, so most of the time it was buying some tool I didnt bring with me. I've been called for light bulbs, dog peeing by a vent and they thought it was leaking water, etc. We made about $100/mo and we kind of felt good knowing we where helping someone out.
Then last year we had a major basement leak. The cheapest repair would cost us $7000 for injections down to the footer from the outside. It took three treatments but it was under warranty. It was now costing us $20 a month for them to stay there since that was the difference between the loan amount and what we made a month in rent. We also got hit for $800 from the city to replace the sidewalk.

The basement leaked again early this year so now we are looking at an additional $4000 to trench from the inside.
As we speak we are in the process of short selling the property. We owe $88k and comps for the area are at $49k. So we are underwater by $40k+.
My suggestion would to find a property management company, they usually charge 10% of rent for their services.
The best thing to remember is you have double the worries of an average home owner, 2 roofs to worry about, 2 water tanks to worry about, etc.

Hope this helps in your decision.
