I am concerned that this property is sucking up money and the repair list is not getting shorter

I would be content paying a high % return annualized to investors but the idea of them taking 10% on their investment ESPECIALLY if it's only a 60-90 day term just seems high.It seems like we would be incentivized with more profit by a shorter term loan.  

Here are just two:https://www.atlassian.com/software/confluencehttp://www.wufoo.com/pricing/Frankly, I'd prefer shorter pages, but our product can be complicated and we need the space to explain the offering.Gurus sell knowledge for a price that keeps changing as you want more of it, and in many cases, never fully deliver.

Usually this does come at a premium to you in the form of him/her paying more for the house, paying higher interest, shorter term on then note, etc. 

(My partner and I are both VERRRYYYYYYY long-term buy and holders, so even this 15yr period is much shorter than I plan to have this property.)Plus about $50K in my share of equity from the improved value on top of the rehab costs(conservative IMHO).

Brie's advice (30yr) is in line with the majority of real estate investors and allows you the ability to aquire more property in a shorter time period.  

And if you do that, then you end up paying a higher rate, a shorter amortization period which raises your payments, and they're typically a 5 yr balloon where the rate can reset after the 5 years. 

Remember, Investment loans are typically for a much shorter span than 30 years, and at a higher interest rate than owner-occupiers can get.

Are they comfortable investing for a period of time or are they looking for shorter-term investments?  

This will allow you  to get the houses in a shorter time period.
