Thank you all for the great advice. I did go see the home, which I found out is owned by the park owner. It did need some work. A window was leaky, so there was a trail of mold from the window all the way to the inevitable soft spot on the floor.
One of the previous tenants had decided to take a wall out and make it a 2 br, but they'd not done anything about fixing the hole in the paneling where the old wall had been.
Most of the electrical outlets in the home were hanging out of the wall.
The water heater had leaked, so more of the floor was rotten. I didn't ask if the water heater had already been replaced or if that was the leaky one.
Most of the inside needed a coat of paint. There was one large, obvious patch in the ceiling that was ugly as sin.
The outside of the home was OK. It's an older home, aluminum siding painted yellow like an Easter egg. It needed to be power-washed, but that's no big deal. Owner said the top needed to be resealed.
He was asking $2000 for it. I told him if think about it.
Got a call the next day saying they'd sold it. I'm not too torn up. It would have been a lot of work to get it fixed up, and give the age of the home combined with relatively high lot rent, I'd only have been able to gross $150 a month. I don't think I could have flipped it for much more than breaking even.
I did learn a lot, though. Good experience. Thanks again for all the great advice. I'm still looking.
