Whether this is another RE, stocks, bonds, Mineral rights, crypto currency is not relevant. 

On another note about 3 years ago we added a coin laundry in one of the units and man it's been doing quite well.

Throw some coin operated laundry in each unit to make up the difference if you fall below $1500 per unit.

I have $4,000 in crypto and $1,000 in stocks.

Plus the trades are aging fast and many will retire and we have a generation of college kids come up who can't tell a 2x4 from a 2x8.Sub 300k inventory (in our market) is the lowest and limited to existing homes - the cost of land, materials and labor force builders into the 400-600 range, so starter homes are like bit-coin: finite supply.Wrapping it all up I dont believe we will see an economic slow down have significant impact on the RE markets - at least certainly not to the tune for 2008.

does anyone have experience with coin laundrys?

Don't get too excited about coin op.

In addition, the shared laundry dryer is not coined and is free to use AKA I will be paying that cost as well.

They flipped a coin to decide who would name the town. 

On the other side of that coin though there are a couple of high rise complexes going in so I suspect that next year or the following year they will be flat if not a bit negative.
