There are several landlords on here, I expect this thread to expand a bit later today - they tend to sleep in lol.
My parents and grandparents owned rental houses but sold them by the time my brother, sister and I were born. My younger brother borrowed 3 grand off my dad when he was 19, flipped his first house and has been doing it for 30 years. He's the only one of us who didn't go to college. He's also the only one with a custom built house on a lake.
I became an accidental landlord when I was laid off in 2008. I moved in with my (now) wife since I was there 4 nights a week anyways. So I've been renting that house a little over 10 years. Had a couple tenants that weren't the best, but I've never been stiffed on rent or anything. Kept a couple security deposits to cover bills/repairs over the years, but for the most part I've had good tenants. One pair of girls stayed 6 years, another girl a couple years. My payment on it is about $650/mo all in, I rent it for 1k/month.
My wife's health took a downturn around 2008 also. She was eventually diagnosed with MS. She ended up losing her house in the 2008 collapse, along with her 401k and all her savings, trying to stay afloat. Her house went into foreclosure, and was eventually auctioned off at the annual tax auction. By that time (2011 or so) I had landed another job, and we were able to bid on the house (we were still living in it) and buy it back for $18k. She had owed approx $120k - the bank never tried to repossess it, they had already been paid off by the bailouts.
So when we finally bought our OWN house together 5 years ago, we started renting hers out. There's no mortgage, and we rent it for 1k/month. The same family has lived there since day 1, no problems. So the $ from that rental pretty much covers the mortgage on our new house.
She wants to flip a house next time to get some cash to remodel our new house. So we're always looking for another opportunity.
