The longer the better, but keep in mind that many of these structures have severe prepayment penalties so using 10 year debt for a 3-year hold creates a problem. 

Purchase price: $90,000 Cash invested: $60,000 Buy and hold that I still have to this date.

I would hold the cash for keys idea in my back pocket until I heard what they have to say.

If that's the case, you'll want to start with a fix and flip (or hold) type of loan, complete your renovations, get it rented out and THEN refinance into a DSCR loan for a long term hold. 

Worst case all USA would have to do is hold out and hold the line as they burn there economies to ashes, to then in end agree to everything the USA is requiring. 

I'm using rent to retirement for 2 new builds with Beaty and so far the experience has been good, however curious to compare apples with apples.

@Philip Beckwith typically in Michigan, you can only do a tax appeal in February.The instructions will be on the back of your winter tax bill.You will need to have great comparables to challenge the City Assessor's valuation.

Seems to me if you hold the taxes the lien holder at some point will need to pay you in order to preserve their rights to the property.

-Build a strong network in Detroit of real humans over a period of months, buy a better deal, hold it for 10+ years, weather early storms:  better chance for success.Even on that latter deal though, are you going to cash flow in month 1 or year 1 or even year 5? 

This is too much out of pocket for a net cashflow of only $175/per month on a holding property.
