I'm looking to create a spreadsheet or some concrete methodology that allows me to track my analysis and utilize any available tools around. 

It was an 8 by 48 foot wide trailer, had an 8 gallon hot water heater and if you were taller than six feet you were in danger of banging your head on the ceiling.Then these men climb back into their ancient but giant Buicks or Oldsmobiles and continue their search for a rental for what they paid back in the "good ole days".Gail

Would have to see the methodology for how this is collected.

The hard work will pay off if you are willing to do the hard work and learn to read people and treat people the way you want to be treated without letting your business suffer.But cash out your 401k and treat people poorly including tenants, outsource all of the dirty work to vendors and property management companies  and you will have a better chance at the nearest casino.Good luck and I sincerely wish you the best.This is the methodology and track that I was thinking.

A house with a bad old design like that screams that other issues are likely like terrible wiring, an ancient electric panel, aluminum wires, asbestos, lead paint, bad plumbing, and a creepy Norman Bate-style basement.

@Jon PierreGreat insights and love seeing your methodology. 

A heat map shows the level of crime...like this...pretty scientificThe data can be normalized for your specific location by establishing the baseline for the city, not the nation...so you can compare relative crime rates to tell where the worst stuff in the city is happening...it goes on a scale and can then be graded:Anyone that creates a crime map based on anything but this methodology is playing a fools game...its simply inaccurate.

We use price per acre methodology in the South Western States with a minimums for smaller lots.  

That methodology/thought process has gotten me far in life and I'm sure it can do the same in REI.

But without such a safeguard in place the ancient rule applies, and the buyer should beware.It is ALWAYS the buyer's responsibility to perform due diligence on ANY & ALL perspective deals or transactions.
