Yes, thanks all for the points to consider. On my house in Lower Queen Anne I have put money into it and brought it up to date (new flooring, new furnace, new tankless water heater, new windows, new counters, etc.). The location is premium so I know it will rent well and it will just be a matter of price. My other house across from Seattle U is also a very good location and will rent. I keep the places updated and well maintained as I just do not have the temperament to let them run down.
However, having a demanding full time job and three kids take up time. So, I have to remember to go slowly and not add too much. I like my full time job and the money it provides.
I may add this other house in if the price is right. I will wait and see. With the comments above I can see I am pretty well positioned for a coming downturn.
I have really enjoyed taking a 1922 brick house in Lower Queen Anne, turning it into a permitted legal duplex, and renting it for a premium. It's been a lot of fun and a ton of learning. I would like to do that a few more times but will remember to take my time and relax. No rush here.
