@Julian BuickThis is a tricky question, and one to which you will likely get different opinions based on who you talk to.The IRS is not specific on this issue, and there is not any case law that we know of you can rely on for guidance.The key premise with the IRA is that there can be no direct or indirect benefit between the IRA and a disqualified party - in either direction.Many tax professionals are comfortable with the idea of joint venturing between IRA and personal funds, so long as:The investment is entered into jointly on day one (you cannot sell or exchange interest between the parties).The initial equity percentage is maintained throughout the life of the transaction, so if you initially fund 50/50 or 70/30 or whatever, you stick with that.The caveat is that in order to avoid any kind of "indirect" benefit, neither party should be enabled to participate in the transaction due to the presence of the disqualified funds.  

If you have a decent condo rental presence with utilities included your competition will be a good index of what something will go for.

If you treat them like you're oh so grateful they should bestow their presence in your unit - they will become a pain in the rear by demanding ridiculous things.What I'd do, is simply raise the rent to market level.  

Don't treat the animal's presence like it is a pet, write an accommodation agreement that you agree to allow an animal in an animal free house based on certain accommodations and agreements.I have property that is rented to pet owners, but those that are not for pets and I give accommodation, will be returned to their original condition when the animal leaves. 

Also, if pets are a concern, you don't have to enter the residence to prove their presence.

The complaints from tenants were so bad he offered local police "Free Rent" for one year in order to bring Police Presence into the building with the hopes of reducing crime complaints.

They don't wander, they are glued to their person and in general totally ignore anyone else's presence. 

The pets presence can't hinder the enjoyment of others in the community "ie barking". 

Tell them you can't afford to replace the carpet throughout, you weren't aware the presence of a cat could be such a problem, and let them out of their lease without penalty.

Having a local presence for inspections and leasing are essential.
