One reference says that if the majority of fund properties are long term rentals and you have an occasional flip, it does not trigger UBIT. 

Not quite ready to pull the trigger.

Main thing is not getting too emotional about these rental properties, and knowing when to pull the trigger on a deal.

However, you have to be very diligent and not just buy a piece of property for the sake of buying i.e. don't be trigger happy.

I am looking at an opportunity:Single Family, Ask price $44,900 (projected purchase price of $40,000)Taxes, $1,400Rent $867/month (rented with long term tenant)Assumptions:5% vacancy10% maintenance5% reserveOh this would also be 100% financed long term with a private mortgage at 4.5%My analyzing spread sheet conservatively shows a cash flow of $4,100/year or $344/month.I really am not sure I want to putt the trigger on this one....My first deal (duplex) is projected to cash flow at almost 6K/year and I really didn't want to look at anything under 5k.I am new to this, but am I crazy? 

Now, I am hoping to pull the trigger once i get the financing I need to buy the first few units.

I hope this gives you a better idea of how to determine if the ROI is satisfactory enough to pull the trigger.

If you want to make a change at some later date to/from an LLC you will have to re-title the property and that may trigger a due-on-sale clause from your lender. 

Furnaces (2006,2007), hot water tanks owned (2010,2011).Anyway I am getting keys on march 27 and are super excited to finally pull the trigger.

This would certainly be a trigger for the due on sale. 2.
