Quote from @Gregory Wilson: A few things there, Brendan.First, an LLC with you as a member and your (wife, son, pal, etc.) partner as a 1% member will file a Form 1065 which is about one tenth as likely to be audited by the IRS as a Form 1040 with a Schedule E rental activity (which I presume you will attempt to show is an active business).Second, you want an LLC because when your local Alabama handyman drives his girlfriend's uninsured truck into a van load of U of A medical school interns on I-22 when he goes  to get some shingles for your roof, on your business, you don't lose everything you have or ever will have to an uninsured claim.
