Reading this though, you will be living in the same house so my thought is are you anticipating unruly roommates which you could screen against, or are you playing it safe by anticipating what could happen? 

I usually have the audio stuff playing while on my drives.

Thanks for playing devils advocate though always good to reevaluate my decision.

Expect the fees and interest rate to be higher, expect the LTV to be lower and likely you'll be paying interest on the full amount of the loan from day 1.I agree with Dmitriy however that UBIT is in play regardless of whether or not there is a recorded lien or an equity partner.

The best way to explaining this is for you to download an IRR calculator spreadsheet or build your own simple one and play around with one.For what its worth most deals I deem meeting minimal IRR standards is 13-15% but you have to dig a little deeper to uncover the real placements of cashflows and capitalization events... and then dig even deeper to verify the assumptions such as occupancy, rent increases per year, and what reversion cap rate was used.Again I don't look for IRR cause its manipulated a lot instead I look at total return on a 5 year basis.

@Stephen Chatto  if this is in a small town no chance that he is going to play that game well. 

I played dumb and asked him where he, his wife and infant son were going to live.

The accountant has to play "catchup bookkeeper" for the entire year --- but (s)he gets paid for it apparently...All that being said, there are other advantages to having an additional checking account. 

Something to decide on now is how passive of a roll you want to play in the deals.

So that can not play any part in your decision.
