For example, new linens, shower curtains, toilet seat, kitchen coffee pot, toaster oven, curtains... even a new tv.

Do I just let them go and be done with it without stirring up the pot?

So right there we know "timing the market" is a complete mirage, it does not exist, it's what people riding the bench say to make an excuse for why they are not doing anything vs the truth of admitting they don't know what to do, or are letting fear win over work. 

Oh, good timing I am renting a house where one tenant smoked huge amount of pot in one room the walls are black with resin.

Once you become married, the $$ pot becomes "yours" as a couple, it is no longer his and hers. 

I've thought of replacing the old cracked sink   with this console sink Last time we had got body sprays and shower bench installed for no reason that no one ever used.

Yes, you will pay into this pot of gold through maintenance costs, etc and there is a heavy reliance on appreciation, but at the end of the day investment is a risk vs reward equation.I have personally used this method 3 times and the tax free money that flowed into my pockets could never be matched by $200/unit monthly cash flow figures. 

You'll need pots/pans, baking utensils, bottle openers, oven mitts, and all sorts of random stuff.

And I’d love to know where you think the honey pot is… Tax liens, NODs, non performing notes etc. 

So far we've taken all the wood off the top (underside) of the porch and replaced it with tongue and grove pine and replaced the single ugly exterior light with 3 brushed steel pot lights attached to a dimmer.
