You get a Capitalization Rate (CAP Rate), which equals your annualized return by dividing the Net Operating Income (you had gross in your narrative) by the purchase price.

(been working and succeeding since 2008 or before, someone you have experience with, good returns, close to 5yr investment?)

Rental income and expenses, such as mortgage interest, property taxes, repairs, and depreciation, can be reported on Schedule E of your personal tax return, regardless of ownership structure. 

-LTR we have 60 days to return the SD. 

Expected return was 15%?  

I'll focus on maintaining the property and optimizing rent increases to ensure consistent returns over the years.

Your returns could be increased if you are willing to rent it by the room to individual students. 

Include text so that states what will happen if the new lease isn't signed by landlord and husband such as the return of keys by all parties date.

This brings me to now, I've taken this approach and have used my own money in lending, but am also bringing in friends and family to take part in these transactions so they can earn way better returns than with CD's.

I’ve reviewed a number of theses DST’s across numerous asset classes  and there performance /returns are generally fairly low and unimpressive.
