Then if they pay taxes on the property for 3 years they can take ownership of the property with a Treasurer's Deed.

One option to consider would to build new inventory in an expanding section of the Treasure Valley.Interestingly, I recently began investing in the Youngstown, OH area.  

and 'surely to be a treasure-trove of historical artifacts for future generations'........

I owned a condo on Treasure Island directly on the Gulf before I was really "investing."

The effect COVID has had on certain markets is very different that it's had on others (the Idaho market has seemed to thrive in many ways).Personally we own/manage several rental properties across the Treasure Valley (both long term and short term rentals) and haven't had anyone with issues paying rent because of COVID (in fact, vacancy rates have gone way down and rents have gone way up), but I know we have a small sample size to go off of.

Me and hubby intend to bid for tax foreclosure in Kansas, but I came across this statement :Any owner or holder of the record title, the owner's or holder's heirs, devisees, executors, administrators, assigns or any mortgagee or the owner's or holder's assigns may redeem the real estate sold in the sale at any time within two years after the sale by paying to the county treasurer the amount for which the real estate was sold plus the interest accrued...Does it mean that even though I successfully bid for the property, but the owner can still redeem within 2 years?  

Even though I am not buying hidden treasures and BRRRRing my way to accelerated appreciation etc They have still worked out over time.

Retain the  treasured ones and weed out problematic accounts. 

As investors age and wealth grows many tend to to move into more passive assets such as notes, commercial properties, and JV deals.Once someone achieves a bunch of money they realize money is not the biggest treasure but time and health to do the things that make you happy in life.These days I would rather take a headache free 15% return than a hard 22% owning a property in a tough area. 4 to 5 years ago you could get houses in A to B areas for 50,000 in some states and drop 10k in and have a 60,000 property for 900 rent.

I know this is a much lower income area, but there seems to be a fair amount of opportunity to purchase low (comparable to treasure valley).
