Hello BP Community,I wanted to reach out and get opinions from local flippers/rehabbers who have done accessory unit additions in orange county california.I have gotten quotes ranging from 150-200/sqft to almost 250/sq to build a new accessory unit and I am trying to dial in a better estimate to figure out what the cost/benefit might be and if this might be a deal. 

No benefit to closing it out. 

This way I’m protected that I purchased low enough while the owner can benefit from the upside if I surpass a certain number.Has anyone ever tried to do something like this?

Might have to educate him on the benefits & tax advantages of owner financing but worth the shot. 

Bear in mind, though, that this is wealth building and you will not be able to fully enjoy the benefits of those investments for some time.

I will also adjust the repairs/landscaping estimate.

You are unable to take advantage of the tax benefits inherent to investing in real estate in the first place.

If the walls are covered to the ceiling with that stuff then I'd say adjust your offer accordingly.

But now it's "Save $45/mo by switching to an adjustable rate mortgage!"

From what I can gather a lot here form an LLC but file taxes as an S-corp which apparently has some tax benefits.
