Do ONLY 30 day leases with 30 days notice with roommates/rooming houses.
Or 60 days if you need at most, never a year lease for a roommate. Ever.
So much easier to get a bad roommate out with month to month leases, and the roommate is generally more careful not to anger the roommate/owner with month to month leases knowing they can be asked to leave at any time. Been there, done that with the 1 year roommate lease-- NEVER again. Never never never. Repeat after me, month-to-month lease with roommates.
Have the roommate agreement specify occupancy limits, including overnight guests. College students (and any roommates) WILL try to let their boyfriend/girlfriend, sibling, friend, etc. "crash" in their room a few nights a week or more. That runs up utilities, risk, liability, noise, parking, wear and tear, etc. My roommate agreement specified the number of nights limited per roommate, with a clause on them not accumulating, not being transferable, and applying to any guest that roommate has that month-- not per houseguest, but total houseguest limits per month.
Have a lease AND have her have a roommate agreement with her 'sub-tenants.'
My roommate agreement specified things like: furnished or unfurnished, maximum occupancy- limiting number of overnight guests as it's bills paid roommate living, if it's co-ed or single sex, no smoking vaping e-cigs or substances on the property, cleaning chores/expectations, no underage drinking, pet rules, what utilities are included up to what limits and what utilities aren't included, etc.
Require a security deposit from each roommate, even if small.
Get a locking thermostat cover; set utility allowances so people won't take advantage of "all bills paid" rooms and have the daughter/master tenant or whoever is paying the utility bills be the person who sets the utilities. Or split utility costs with each roommate paying a utility deposit upfront and/or adding their name to the utility bill.
Have a strong lease with occupancy limits (including overnight guests-- it's a roommate lease, my city allows roommates to specify this), quiet enjoyment/don't disturb neighbor clauses, verify a student's court record search for evictions and criminal history (they might be young, but still can have them), noise rules, and a strong disclaimer.
Strong disclaimer was my biggest rule- waiving of inconvenience, injury, loss of property, etc.
I would have your daughter rent from you as the master tenant-- then the roommates rent under her. She's got less assets to go after than you if a roommate tries to sue.
I wouldn't interview your daughter as a property manager... if you do this, it's doing it as a favor to your daughter. If my normal tenant asked if they could rent out rooms, my answer would be NO. NEVER. Not in a million years. You're doing this as a personal favor to your daughter.
This is your main source of income? Does your daughter already live there? What if your daughter gets fired and can't pay you--- are you going to evict your daughter? Charge her $2000 to replace the stained carpet? Have your property foreclosed on if you get $0 a month from her? Expect, at best, to get your normal rental rate paid by your daughter. Roomming houses aren't huge money makers after you factor in vacancy, taxes, and utilities if you're doing "room for rent- bills paid."
It would be so much cheaper and less risky just to rent your daughter a $500 bills paid room in *SOMEONE ELSE'S ROOMING HOUSE." If your daughter can't afford the rental rate on her own, no roommates needed, you're taking a risk-- and you'll have to pay the difference in what she can't pay. She'll have to compromise on rental qualifications to have no vacancy with roommates if she can't afford the rental rate on the house on her own, and that's risky, at best.
I would have her choose older students, no 18 or 20 year olds. Underage drinking is too common, and 18 year olds don't know how to not damage a house more often than not. I found students and young professionals 24-28 so, so, SO much easier than 18-22 year olds... yuck! At 25, she should seriously expand her reach to young professionals... 24-30 is an ideal age. By then they have often toned down the partying somewhat, gotten a job (fewer late night loud parties that disturb neighbors), care more about their credit, have some idea of the damage they're doing to a property, etc. An 18 year old freshman will generally be whiny and complain about everything, while a 25 year old will appreciate the cost of living and value of a "room for rent." Find roommates with a job and school, they're less likely to be entitled "call their mom" types that whine about everything and annoy you. Upper 20s/lower 30s young professionals are so much easier- they've usually rented before, are trying to settle down and start a career, and know how to work a washer/dryer-- unlike many 18 year olds these days. o-O
