I completely agree with @Jon Holdman Partnership is so tricky when the money and labor (un-quantifiable) are involved.

So I think there are some bottom-line returns, but hard to quantify any individual little thing you do..

to me, that was a no brainer and helped quantify my potential risk.

Wouldn't it be great if it could be based on knowledge of investments, current investment holdings or other quantifiable factors?

Stuff like that.While it can be hard to quantify, as Rumsfeld put it, the unknown unknowns, how comfortable are you feeling right now with what you need to do and what your next step would be?

In other words, hard things to quantify, but there are benefits

I typically hire an inspector to give me an idea of any major issues (I quantify that as anything above 3% of purchase price for most of my projects).

Quantifying the net interests of the holder from the asset's liabilities.

So if you wanted to try renting it for a year or two you would still qualify to sell the house and take the profits tax free as long as you could still quantify that you had lived in it for 2 out of the previous 5 year period.  

I don't have enough data yet to quantify how much, but it does work.Hope this helped!
