That time when a person is interested in an idea, but it's still just an idea, an imaginary, intangible thing, a thought or feeling, and that person has no plan or path or methodology to turn that idea into reality.Until very recently (like last week), that was me.

In theory, to maximize this methodology, I would put down 25% on 10 properties then buy in cash with the rest of the funds?

I have no interest in selling anyone on it, and buy-hold may indeed be a preferred methodology for others.

Or do I need to follow some kind of methodology? 

I would be careful of that methodology.

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.

Both of which are true for me.But it doesn't describe any methodology for how I might adjust min/base/max per season once I've created the profiles. 

Appreciate any links to other posts explaining methodologies.

And there will be problems.Because most architects work on a plethora of building types they are constantly juggling code requirements for different methodologies.

I am new to real estate investing and interested in forming a local group to better understand the Austin market and BiggerPockets/realestate investing methodologies.
