However my agent said roommates are okay? 

My roommates and I paid our rent on time, never caused any problems, and she had problems fixed whenever they came up.Anyhow, when I moved in, I signed the lease and I know that I read the lease because I always read all of that boring stuff.

I have had mostly 1 roommate at a time, although there was once a family of 6 (Mom, dad, and 4 Kids) living with me (TOTAL NIGHTMARE).

As a female she is going to want a certain "class" of roommates so she feels the most comfortable in her own home.

Be ready to jump at opportunties.A thing that alot of friends have done is to have roommates.

These were all helpful in my follow-up discussions with the potential roommate/tenant.

They are all short term rentals so everybody is on their best behavior and we don't ever have to deal with that roommate who always leaves dishes in the sink!

Roommate is not applying for the loan. 

However, we have a couple of student properties which rent by the room - target clientele is predominately international students - and have absolutely no problem filling vacancies at these properties in winter ... particularly the start of winter/spring term in January, which is about the time some folks decide they do not really like their roommates who party all the time and are looking for a new place to hang their hat.

We saved money by sharing with roommates, that is how we got the pot of money to buy our first house.
