It's been a while - 3 months! So I thought I'd give an update. I kept the condo, fixed it up (mostly smoke treatment, which was successful! and a new fridge), and rented it. The cost of fixing it up and paying condo dues while it was empty was about $10k (that included moving out my mom's belongings) and took 2 months. It took no time to rent the place - I signed a lease a week after posting the ad. The tenants are financially solid and seem very appreciative of the space, which means, I hope, that we can just coast and all be happy.
The big question will be expenses - besides condo dues, insurance, and taxes, there have been no expenses since I rented it, giving me a cash flow of about $2500/mo. Meanwhile, In July, I spent about 1 hour on "property management", so I'm pretty happy so far. Obviously there will be more repair costs over time, and rare, bigger expenses. I will see where things stand in 1 year, but overall I'm pretty happy getting revenue equivalent to 1/2 of my income each month. I feel I have a new level of diversification, and Thanks, mom!
I'm tracking home valuations over time, too, to see. So far home value has increased over a few months, so I'm glad I didn't sell the property back in May!
Thanks for everyone's advice and thoughts!
