After 2 years you can apply for a “Rent consideration” (I think that’s what they called it) as long as you still live there and that may allow you to increase rents by more than the annual allowance (probably designed for unit that are very low rents).

Quote from @Deirdre Lizio: This is not an "either-or" consideration.

Does the bank take into consideration the income from the other units?

You've given me some solid pointers/items to take into consideration for future deal analysis, so thank you for that.

@Collin Hays@Jon Martini agree that tax considerations shouldn't, by themselves, drive business strategy. 

It's definitely tricky because you want to be considerate and you are also running a business.

Here's the bigger lesson I learned: If a tenant asks for special considerations, or reduction of fees - those are ALWAYS the ones who are the problem tenants.  

Marcus & Millichap’s report also mentions the importance of universities to Pittsburgh’s rental market, “The considerable number of universities in Pittsburgh will provide a diverse hiring pool for the area’s growing tech sector in 2017 and beyond.

definitely need to have lawyer look at it.Risks/additional hurdles- On the practical side, the absence of deeded rights makes tenancy in common ownership considerably more risky than condominium ownership, even where the TIC owners have separate financing.

So, in your considerations, I would park right there for a bit and determine how this would look for you.Since you have about 2.5 years to think about it before you would need to spring into action to take advantage of the rollover for tax advantages, maybe you try on a rental and see how it fits.
