I know there are potential pitfalls and lots to figure out about this plan, but I'm specifically curious about how this type of arrangement would affect the owner-occupied mortgage situation.

I would avoid any partnership that is not equal shares, because it can go sideways very quickly in that arrangement. 2. 

@David Ribardo and @Joe C jump in with any edits/comments you might have Purchase Price $149,900 (50K a door rule looks good) Three units total gross/month 2239 (1% rule looks good) Fixed expenses: Taxes 2517, Trash 1125 (375/unit in Allentown unless private collection deal previously arranged) Insurance: 703 Common Electric: 519Water/Sewer: 802Allentown Fee: 225 (75/unit/year) Variable Expenses:  Vacancy: 2239 (One months rent of each place, or 8.3%) Management: 1800 (50/door/month) CapEx/Maintenance: 3000 (1000/door) Total Operating Expenses: $12,930 Total Gross Income: $26,868Net Operating Income: Op Ex - Gross = $13,938 Divide your NOI by the cap rate your looking for and you have your offer price.

In exchange, they can gift her the house in their will or a similar arrangement. 

I would accept that arrangement in my cheaper rentals but if I was renting a house in the 2-2.3k range, probably not unless you paid the full amount up front.

If you still feel the need to send Brady out we can arrange that.Should I be worried?

Sounds like he is bringing  a lot to the table, though, so moving forward maybe consider a different arrangement.

@Patrick Hall@Linda Weygant@Yonah WeissThe distinction is between (a) Individual Retirement Arrangements - IRAs and (b) Qualified Plans (e.g., 401k, profit-sharing). 

I would imagine base case is a commission only arrangement, if possible.Thanks for any input.

I'm eager to get a better understanding of the terms of the arrangement, and particularly the specific documents used to secure and document the transaction.I'm reaching out to you via BP message now...
