Adding 1-2 more coin-op laundry and PV solar for common areas and dividing the utilities are my future value add projects.

Most recently he has been complaining that dryers in our building (coin operated) do not get hot enough and that it is affecting his quality of life (literal quote).

I've listened to the BiggerPockets podcasts and what always seems to evade me is how people go from their first investment (or first few) to the next handful.I've followed much of the advice (bought my primary residence in Denver, CO in 2012 for $320,500 and have rented out the basement consistently since then effectively living for free - yay house hacking!).

This is unit has a coin laundry area, anything I should look for or know?

CapEx and reserves are opposite sides of the same coin. 

As a result, no money is accepted onsite, no machine coin bins fill up, no vandalism and tenants dont need to collect quarters to do laundry.

Coin-op laundry for example.Bottom line is that I think you have a lot more work to do understanding how commercial real estate is valued and underwritten.

Any other value-add opportunities like putting in coin-op laundry?

I bought a townhouse in Boulder, CO in 2016.

On the flip side of the coin, we see tons of offerings that we pass on.
