@Cameron C.
I'm not sure how your market it, but here in SoCal around the colleges, room rentals are generally $hit. Either you live with a family and deal with kids and dogs and cats and mess, OR you deal with a retired person who yells at you for coming home late (yes, 9 p.m. is late to some). Funny story, I actually had a tenant who was nearly assaulted by an elderly lady because when she came home in the afternoon, she turned the door handle the wrong way, which cause it to make a lot of noise. She immediately put notice in and moved into one of my homes (and paid about $250 MORE per month). Even worse are the idiots who buy a house and rent to college kids with 0 structure, 0 management skills and 100% interest in taking advantage of desperate kids. Eventually their house falls into disarray and they only way they keep rooms rented is by lowering the cost so low, only the deadbeats will live there.
I'm able to charge well above the market rate because I have a really well done house with all the fixings (leather couches in living room, 60" wall mount TV with HD channels, etc.). All rooms are furnished and all utilities are included in the rent. I average $700 - $1,000 in bills per month but am able to collect well above that by including it in the rent at a flat rate. If you want to chase people for their $12.56 share of the electric bill, $4.12 for their share of the gas bill, etc. then be my guest, but it's not scalable and definitely not cost effective. I also pay a maid to clean common areas twice monthly ($60 per visit, it's a deal for sure). People will pay the premium to live in a beautiful home WITHOUT BS RULES, PETS AND OLD PEOPLE lol. I also do month-to-month only in order to keep my vacancy at 0%, which I have done for 4 years now for multiple properties.
If your house has a kitchen, den, family room, etc. then I recommend converting it to a bedroom. You only need a kitchen, living room, bedrooms and bathrooms (and laundry on site is a huge plus, but for God's sake don't put coin op... if you had 30+ tenants in one house then go for it but for less than 10, just make it free and up the rent). Everything else is wasted space. I actually love to knock the wall out between the kitchen and living room and put bar-top seating area. Nobody wants to sit down at a dinner table with randoms, but bar-top with food cooking, tv playing, its a great social place for them. I usually put a pool table and laundry in the garage, although you can convert the garage to a living space for more rent (this is definitely more risky, cities don't often like converted garages).
I don't have all the answers, but I'm more than happy to share my experience over the last several years with you and help in any way that I can.
Oh, side note, I living in the first place and rented the rooms out while living there. Once I moved out, the management was almost the same. You can do it absentee easily. Just make sure you have processes for everything before you do and keep a tight control on things because 1 bad tenant can piss off everyone and you'll be filling 6 rooms instead of just one LOL! Oops :P
