Elmo area but can't find much info online about where I can buy and operate. 

See if you can get a copy of The Millionnaire Real Estate Investor by Keller.The Slight Edge and Atomic Habits too.Awesome board with many smart people having own suggestions and ideas to grow wealth!!

Search on this forum and you can see the buffer contingency numbers which people how have invested and got burnt come out with and maybe use  a median to calculate based on that:)

Check out the "Enemy Method "You can find videos.

You can pursue a quiet title post closing to clear this up and add value.
