These are the universal elements and actually might not be a bad place to start.

@Luke H.Hi Luke,  As a private money lender myself I will focus on one element of your deal---5 years is a long time to be finally paid. 

To replace your income you need to flip a lot of houses, I'd do the math with an average 10-15% profit margin, because you have to account for some turds.The other opportunity is to change your job and take out the element that you hate.

To clarify, my focus isn’t on analyzing T-12s for purchasing a property but rather on developing a solid T-12 for managing my property effectively and for use when I eventually sell my investment property in the future.I want to ensure the T-12 I create is both accurate and straightforward, serving as a reliable tool for tracking performance over time and presenting the property’s financials to potential buyers down the road.If you have any advice on key elements to include or how to structure it for these purposes, I’d greatly appreciate your insights.

Every customer is assigned to a group of team members there and I imagine each team varies slightly in quality given the human element!

I got to my current financial success through a series of well thought out endeavors but with a massive sink or swim element as I am often self guided..."

So that time element is important for me to consider. 

It’s an interesting trend that benefits both the investors and the local population, as it helps balance the overpopulation of cities while preserving rural heritage.Another point you mentioned, about “not being for or against investing in Europe, but that it simply adds more elements to manage,” is very insightful.

That said, the right team on your side can make the permitting process and inspections far less painful.I’m curious... as you refine your plans, how do you see yourself balancing the home’s original character with these modern upgrades, and which element of the design do you think will win over the pickiest buyers? 

Imo, this is the critical element.
