I got started investing in Real Estate with a Large SFR Student Rental. Held it for 5 years before selling it, so can give a little input from what I learned.
-As you mentioned Student rentals have a higher turnover rate, and can be stressful finding a new group of students to rent for the following year. Every campus has pockets of houses within the neighborhood that are more sought after than others for students to rent, and getting in those pockets can drastically reduce vacancy rate, and stress. Better area, attracted more applicants, which gives you a better more responsible group of students to rent. With your Daughter going to school there, i'm sure she would know the blocks within the safety zone that are better than others. Close walk to campus and night life.
-More bedrooms seems like the way to go on paper since it produces higher cashflow by renting by the room, but it increases vacancy substantially. Where I was at, 4-5 seems to be the sweet spot. Anything over that and it was harder to find that large of a group of students looking to rent together. My property held 6, but usually was averaging 5.
-If you can find a property with unfinished attic, its a potential a way to add 1-2 extra bedrooms if needed, based on how the permitting works there.
-When looking for properties would try to keep at least a 2-1 ratio for bedrooms and bathrooms, helps to attract more groups of students.
-If you can include the cost of a monthly cleaner into the rent, it is well worth it. Will alleviate a lot of headache managing from getting calls about the drama within the house.
-I Learned to build the cost of utilities into the rent as well. Would get calls from students complaining about other students not paying their share on time.
-When looking at new properties, inflate your reserve costs for vacancy, repairs, and cap ex.
-Leases were written to be Jointly and Severally, to hold each individual, and the group has a whole liable.
Hope some of this helps!
