My question would be: why did you change your methodology for the second one?

If the seller balks at the buyer's right to assign without the seller's consent, the next best clarifier is something like this: "The buyer has the right to assign this contract subject to the seller's written consent which shall not be unreasonably withheld".Personal experience has taught me that leaving the contract silent on the intent and methodology of how assignment is executed is a bad idea.

Everyone can agree or disagree that IRR is the exactly perfect way to calculate investment returns, and in fact, those in academia, would correctly argue that using NPV to determine total value of investments is a better methodology.

And I am looking to use the BRRRR methodology on the properties.

Flipping & BRRR'ing a property are the exact same methodology with different financial outcomes.

It includes, among other things, a comprehensive map of the Cleveland area, grading each area from A+ down to F, using a consistent, objective and transparent methodology using publicly available data.

Could also consider some Cleveland neighborhoods with a 'C' grade, such as some parts of Old Brooklyn or North Collinwood.I've created a comprehensive Area Guide with dashboards on the most common areas (neighborhoods and suburbs) for investing in the Cleveland area -- it includes grades for each census tract (objectively scored, only using publicly available data, and with a fully documented methodology).

All of these things expand your current way of thinking and expose you to investment ideas / methodologies / tactics that you might not have otherwise thought of. 

Generally, tax advisors will allocate the purchase cost between investment and personal use based upon square footage, but other methodologies are acceptable as long as your tax advisor deems them to be defensible under an audit.
