I never believe Airdna "methodology" is accurate.Data is there from Airbnb itself ; and Airbnb already announced that their ADR in US is only hundred fifty bucks LOL.  

Why would anyone sell the ability to make millions with a methodology as simple as following this check list?

once your floor is level its time to begin. your very first course of tile is very important/I did not really understand all the books methodology of measuring and finding the square etc. what I did is laid one or two courses without thinset but with spacers.once I was confident that these were straight I laid the next tile next to them. point to note when laying the first cemented row of tile next to the trial run be sure not to push the the trial row out of position or you will end up being crooked. tip four get the right consistecy do not mix too much at once. for a beginner perhaps 1/4 of a bag then try 1/2 bag.

My advice is to get with a real estate savvy CPA to get tailored advice and also a solid bookkeeping methodology to implement. 

When you read through the BBB's posted methodology of how non-accredited companies are scored - and the assumptions made - and see the BBB site shows only thee registered contacts (reviews or complaints) concerning the company, the ranking affords ample goodwill towards the organisation (essentially, you are assumed to do good, until we hear otherwise) and is statistically insignificant.After investing an evening doing a little background work on Renatus, I still do not see clearly what you are selling, nor how it would benefit me more than seeking accredited education from a university or community college at a lesser cost?

Additionally, our usage of more "realistic" evaluation methodologies for Replacement Cost and Actual Cash Value coverages with no co-insurance requirement is another differentiator that sets us a bit apart.

From my understanding, this is a very niche methodology, the dealer and the lender are affiliates of each other. 

The code itself is really just a framework and does not dive into specific details on accepted or invalid methodologies.  

@Ibrahim Hughes I use Trello with a Scrum/Agile methodology.

Makes a huge difference.The methodology is at the bottom of the page.
