However now that we're in escrow the title company will not insure until the wild deed is expunged; meaning they want it erased from title as if it never happened even though it has been overturned and title is in good standing.

you can use other calculations as well like ROE(return on equity) as a metric to give you more clarity or ROI

If it's stabilized, more capital and chopping up equity will reduce cash-on-cash and ROE. 

If this is truly a smokin' hot deal, it should be obvious with just four simple numbers: income, repairs, operating expenses, and price.Honestly, I don't know any cash flow investors who spend much time obsessing over price per square foot, GRM, ROE, or IRR.

An LLC, liability insurance, umbrella policy are all things to mitigate this type of risk.That is talking from an entirely risk standpoint, and not touching on ROI, ROE, etc...

You explained it in more detail.I just found out from the attorney that represented CitiMortgage that the reason they dropped the foreclosure/Quiet Title is they realized that they were not going to be able to successfully overturn the Tax Deed.

But if instead I am an "Equity Purchaser" (i.e. buying the house with equity in it after and NOD but prior to auction) if the terms are "unconscionable" the courts can still overturn the contract and go after you for losses etc.

@Shekhar Ramaswamy you need to calculate your return on equity (ROE) to let you know if you should add leverage/more debt.
