So let them keep doing that and spare yourself all the expense of paying your own mortgage.Are the rental properties cash-flowing? 

@Randall DemaryI would try and make room for a compact stacked or stackable W/D if possible.

The advantage comes from the fact that when excavating on the up slope, more often than not you are constantly cutting into the terrain and much of the soil remains undisturbed, or at least what is disturbed is compacted with the excavator while creating access ramps, etc...

When you do both then you are working both sides of the accounting equation to increase your net worth, but also when you are building assets that puts you in a position to be able to take advantage of opportunities that might come along in the future.Example: Say you calculate you can live like a Spartan using all your spare cash to pay your debts off within 8 years.

Roku TV's and spare Roku remotes just as others have said. 

In their spare time they could rekey locks we removed and collected in a box, and create new sets that were ready to go.

I have tried Glacier, Aqua, Kohler, Delta, Sterling, American Standard and some others.I have had issues with delta compact elongated.

Make sure it's always locked so hobo's don't sleep in it, get compacted, or dumpster dive.

(3.5% down 3.875% intrest) then house hacked the spare bedroom for $650 a month while completing renovations.

If you already have tile, and can get some spares that match, do it while you can get them and just replace broken ones as they come up.
