UBIT is generated two ways.

Where are you generating leads and for what end? 

.: I haven't passed this past legal review so for what its worth: Part of my standard requirements for everyone include income is at least 3X rent, minimum credit score, say 640, Clean record and no evictions as well as deposit is paid in full at signing of lease and 1st month rent is paid in full prior to handing over the keys.

However, there are still plenty of tax benefits when it comes the income you generate from your multi-family property that you can deduct from. 

Instead of 40 houses cash flowing $200 each or $8000/month, you buy 10 houses and pay them off for a cash flow of $10,000/month with 1/4th the headache.People don't understand the amount of time, energy, and stress involved with managing a lot of doors, especially if they are lower-class properties typically needed to generate cash flow.

Here is some clarification:When property inside of an IRA is financed, it generates UDFI (Unrelated Debt-Financed Income), the income derived from the leveraged portion of the property. 

That’s why I was shocked to see it’s only generating half of what the maximum rent is.

No more messing around.If they get out without issue, fix and clean whatever was done and thank your lucky stars you got out with minimal problems.

They don't communicate well, don't take responsibility for their actions, do not clean or maintain homes well, and will shaft you when it's time to leave.Other than that, it's a pretty good system.

And your cleaners will need to clean out the fireplace ashes each time, make sure the damper is closed, bring wood in or have a pile near the door, whatever.
