@Alex HowardYou may be required to complete a partnership return to properly allocate the split among the profits of the flip."

I know of a partnership who is actually one of our clients.

Easier to manage as an LLC than as a partnership. 

The repairs on a front loader will be much more costly than on a top loader.What I would recommend doing is writing in your lease that the washer/dryer is fully functional upon the tenants moving in and if any repair/replacement is needed moving forward it will be the tenants responsibility. 

The place is a duplex that has great cash flow and a cap rate of over 10% but it is a hassle to sell because of the partnership and I can’t work with him anymore.

It's been my experience that there are no original ideas out there - and the very few ideas that are "original" quickly get what I would call clingons riding shirt tails (watch the movie "The Big Short" and you'll see exactly what I mean).If you're defining it as not following trends, I'm still not sure how that goes because people are into everything....you've got gold/silver bugs, you've got REIT investors, you got investors that follow master limited partnerships, you've got various aspects of real estate, etc., etc.Personally, I read and digest what other people have done/are doing.  

Sorry, but I gotta throw a penalty flag here on Lucas Machado - some of what he said shows a lack of understanding of basic Adwords functionality.

The cash on cash return will be much higher and will be a function of your closing costs, rehab costs and of course mortgage rate.  

I apologize if this has been asked or answered before but I can't seem to find it in the search function.

Let me know what types of investor partnerships you are looking for.
