I can look on Zillow, but that’s not always very accurate.

I've prepared a data spreadsheet and would like to know how accurate is my data, and if there is anything important I missed.The blue color data was taken from the US Census Bureau, green from the Bureau of Labor Statistics, and black from different sources, including Bigger Pockets, Zillow and other sites.Thank you!

However, you can only use 50% of it under the non-qualified use rule.That's not accurate at all.

I'm still honing in on renovation costs, etc. to make sure this is accurate... but in these scenarios would it make more sense to do a "flip" and exit immediately rather than buy & hold?

My question when trying to accurately calculate cap rate, I assume all expenses are to be included like cap ex and property management?

There's a lot of discussion around partnerships, private lending, and hard money, but I don't see much discussion on the actual mechanics - what these arrangements look like in practice.My hope is this post can serve as a reference for those starting out, so we may get a better understanding of how these strategies are actually implemented as well as an ability to more accurately predict the profits and returns you and your lenders and partners can expect.If those with more experience would like to revise these numbers and statements, it would be most appreciated.These scenarios assume you, the flipper, are bringing none of your own capital to the deal.Typically, this would mean 1 of 2 scenarios...Private Lending - Someone you know brings 100% of project costs (purchase, rehab, acquisition costs, holding costs) to complete the deal and in return, they get a certain percentage return which comes out of your profit.Hard Money + Partnership - You get a hard money lender to cover 80-90% of purchase+rehab and a partner to cover the remaining 10-20% as well as acquisition costs (including hard money origination and points) and holding costs (including hard money interest payments).An aside about the structuring...Private Lending - A promissory note is created, and your private lender lends to you or your business. 

Not sure which is accurate or even if those are market rents for Waterville. 

www.renovationgurus.com They even have a great tool that can show you how to estimate your renovation work fairly accurately. 

Your other numbers seem accurate.

Market rents are probably accurate at $450/575.
