I have a buddy who bought an apartment building next to college that kept expanding in Central Florida and the school now leases the entire building from him in a really nice net lease. 

Tell her if she wants to live separately, then she can move and take the buddy with her.Legally, from my understanding of marriage and co-owners of a property, it would be like any other business partnership where the partners are equal. 

I added some language to my lease requiring it in hopes that next time something like that happens i'll just point to the lease and say sorry buddy pls make a claim on your renter's insurance.  

Don't rent to students who bring in a working buddy with a night job like food service/bars (he's got nothing to do but party ). 

A buddy closed 242 units while deployed.Check out the Start Here page http://www.biggerpockets.com/starthere Check out BiggerPockets Ultimate Beginner's Guide - A fantastic free book that walks through many of the key topics of real estate investing.Check out the free BiggerPockets Podcast - A weekly podcast with interviews and a ton of great advice.

Where do the students want to live what are they paying, what is included do they advertise for housing in the office.A buddy does it.

Why not save 30% on utilities and go green, plus it is def as good selling point to prospective tenants :)My buddy gave me one big piece of advice.

Call the person claiming to be the landlord, make up a rent number different than what the applicant has listed as their current rent and if that person "confirms" this as the rent you know you're dealing with a buddy, not the real landlord.Gail

If that logic is true, then I guess that means that if the tenant has any other crazy thing in the home, I'm liable if one of their buddies injures themselves on that too.I'm not saying that isn't possible, but I am questioning how our legal system allows that kind of silliness to go on.A landlord should not be liable for any toy some tenant's friend hurts themselves on.

Probably because his buddies are coming over for the game at 6pm lol
