I haven't looked at the neighborhood but from what you were telling me earlier I'd give the income approach at least 80% of the weight and sales comp 10-15%, with replacement costs rounding in around 5%.In the end though If I recall correctly you're looking to refi anyway so a lender is going to use their own methodology.

Just be careful of the MVP/Lean Startup methodology when interacting with the FCRA.

Is Ken's methodology incorrect since Grant said NMD doesn't work?

An engineering-based study is the IRS' preferred methodology.

Is there anything else relevant that you think the owner ought to know about the company or your methodology?

  $1600/12/10= $13.33.In addition, using a percentage for maintenance/cap ex is a terrible methodology. 

I would recommend a serious methodology.

I feel like our methodology has almost shielded us. 

For now, as the two properties are too small to refi, I will sell them and buy larger properties with financing using the same methodology as you did on your first two.

You will get more to depreciate, and it is the IRS' preferred methodology.
