The MCB market was a bit contrived compared to open market, MLS residential sales, but the point is that our modeling was to result in a single purpose, actionable result.

If you do inspections, it is for the purpose of identifying maintenance items.

My purpose for writing posts on BP is because I like to help investors so they don't think that investing is more simple than it is and so they don't mistakenly think they found the holy grail and lose their money.

It's commercial grade stuff that can be used for the exact purpose you're describing.

I have been putting 20 year loans for the calculations just for the purpose that I would like to retire in that time frame.

One thing I want to ad is you need a consistent routine for storing your receipts and also make notes as to why that transaction was a business purpose.
