I assume you mean Portland, OR. I have a SFH and duplex here. My experience is that yard maintenance companies here charge a lot and don't do much other than "mow and blow". And even then they don't do a great job. Also, seems they want you to sign on for ongoing monthly maintenance ($300!) even though it's not really necessary some months (winter). So I now have tenants responsible for yard maintenance. They don't necessarily do a great job either, but has worked out so far. One tenant really liked gardening and did things well.
Re: water bill....the water bills for SFH in Portland are VERY high, relative to other places nearby. Much of it is fixed cost due to large infrastructure projects (google "big pipe"), but there's also been some political finagling. The per unit water bill in a high rise condo is about $10/mo per person, whereas for a SFH and smaller plexes it's about $40. The Portland Tribune has a good article explaining it all. My duplex doesn't have separate meters, so for years I paid the water and bundled it into the rent. Then my tenants had unauthorized people living with them and water usage went way up. Last year I belatedly discovered RUBS (better late than never!), so now the duplex tenants pay $30 pppm for water.
