I plan on keeping this property so the last thing I want to do is place a family in here and someone gets sick from mold(unseen) to me.My solution was tear down and build a binishell (system) with green tech(solar panel system, rain water purification system, etc...)

The rent was below market and the late fee didn't seem to make the tenant flinch when they paid the flat late fee per month.This past renewal, I had decided to try a different tact with the tenant to have them pay on time.  

I'm not sure what your management team costs, from what I've seen most low rent places take a flat rate instead of a percentage. 

Could anyone recommend a "Flat Fee list on the MLS service" in Washington state?

This is just my very opinionated $0.02 based on the real estate purchase transactions that cross my desk, I offer no opinion on the value of solar panels in terms of saving the world or any of that.Owned free/clear: No impact, typically zero value add.

All the electrical was 12ga wiring & all the waste pipes are 4inch solid copper.Every time we did a rehab & cut into an inside wall we would discover that it was once an outside wall complete with 1.5" pine shiplap board, tar paper & layers of drywall intermixed with paneling.

You'll need to find a local real estate agent or flat fee listing service for that.

We bought a nicely updated 2 flat last fall (3 BR/2 full baths, in unit laundry, yard, garage), which came with tenants.

Without knowing much about your property or location I'd say a decent thick LVP with foam backing is a reasonable alternative to tile but the substrate needs to be very flat for either of those so preparation is key to a good result.
