-They would get 60% equity and 60% of cash flow-Cash flow won't be positive until 2-4 years later-When we eventually cash out refi to buy our next property, which may be in 2-4 years as well, the partner would get their 60%-If this isn't attractive enough of a deal, would 70% or even higher make it worthwhile?

If it is fixed the low rate may make the future aggravation worthwhile.

BP has plenty of money that they could easily pay for blogging if they wanted to, but that creates a content and conflict of interest problem - is the blog post content worthwhile or is it just a paid advertisement?

What we did get though was a free place to work and what really at the time made it worth while is I got first look at all the agents pocket listings..

To @Drew Sygit point if you can provide them a large number of units (say 20) that they can manage in the same time 10 others take because of how you interact with your PM, then maybe its worthwhile...But typically I actually don't want to receive discounted pricing on services from any vendors.

Save it in case the expense comes up at some point in the future; invest it so the money compounds in the coming years; donate it to a worthwhile charitable cause; spend it on some toy or doodad that keeps burning a hole in my pocket; whatever.By including the money in the Contingencies category, I've already "spent it" on something.

I know that's added cost, but is it worthwhile, or just focus on digital marketing?

If you anticipate large capital gains from another property, then you may see a worthwhile difference.

I know that most everyone shoots for $100 a door, but given the fact of close to 0 out of pocket would it be worthwhile?
