My hope is to be able to use the BRRR methodology and use her cash to buy.My problem that I am most stuck on is how to structure everything, all the way from the beginning.

Kind of hard to compare Apple's and oranges and not sure if that it's possible to prove it through that methodology.

Now I just went and test drove a Tesla today and going to buy one.. now they are not traditional care sales folks but they have their methodology that is well trained and well presented.. the salesmen just did not wake up one day and come to the office and say hey the company is sending me leads what do I do..

In other areas, other types of houses, different level of finishes, and different contractors, that wouldn't even get me paint and carpet.Spend some time reading other threads about how to estimate -- learning the methodology takes time and practice. 

Over my past 25 retail sales, I've averaged nearly $25K in profit, so being conservative is working.I've hit $40K+ profit on two projects ($145K and $165K resales), I've hit $30-40K profit on 6 projects (resales from $95-175K), and have only come in less than $15K on two projects (my very first flip was one of them).So, I really like the methodology of shooting for "singles" but being conservative enough that they often turn into doubles and triples (and maybe an occasional home-run, depending on how you define it).

Well, <sigh> I'll take a risk here and explain my methodology.

In reality it is entirely dependent on the methodology used to calculate the NOI.  

Nothing can, simply because every area is going to be different, every contractor is going to be different, pricing changes seasonally, material prices change monthly, there are different levels of contractors and quality, there are different levels of material and quality, etc.What the estimating book will give you:* A step-by-step methodology to learning how to walk a property and assess its condition and the repairs that are needed.* A step-by-step methodology to creating a scope of work for the renovation.* A step-by-step methodology for how to inspect various systems of the property to determine what is working and what is not.* A set of templates for the line items that will end up on your scope of work.* A ballpark range of pricing for each of those line items.

I have been reading a lot of books on Real Estate investing and methodologies, listening to the podcast's on BP and going to meet up groups to learn more. 

Supervising appraiser had to come out -- remeasured and, of course, backed up the methodology of the understudy.
