Also, is there ANYTHING I'm missing in line items on this sheet?  

The majority won't qualify for traditional financing, hoping that funding won't be too difficult to secure if the deal is good enough.

I am an experienced CA Broker with a few years of background both in traditional Real Estate transactions and loan process.

I also highly recommend Ridge Lending in Oregon for traditional (not hard money) financing.  

I've seen prepaid items such as taxes and interest rolled into loan on initial good faith estimates (about 4K) for refinance.

Getting tradition loans for something like this is not very easy in this area .

Is it feasible for me to find an investor that would buy the property from me knowing they could sell the property in 90 days to the traditional buyer?

Yes, the title co. can tell you who traditionally pays what costs, and include that in the contract language so it all clear and spelled out up front.

(A bucket list item...) and now at Cuyahoga Valley National Park here in Ohio.  

The benefit is that the funds can be liquidated to cash so that they become FLEXIBLE and can be used for anything (marketing, payroll, operations, office rent, etc)...not just acquisition or rehab like traditional real estate funding sources.
