I could wax on but those are a few points to consider.

If the home is on septic that's a whole other ball of wax to deal with: stuff being put down the drain that shouldn't, septic blockages and repairs, etc.Stay away from mobile homes, stick to sticks and bricks investing.

I put on upbeat music and usually have a candle burning. 

A standard wax ring will work for anything up to 1/4 an inch.

You have the best resource possible in CA by subscribing to Property Radar.If you need trying for equity purchase deals, go to Ward Hsnigan's foreclosure forum and take the one-day equity purchase training.People who are new to real estate see others who are successful and don't want to do the "wax on, wax off" work first.

Looking for service/contractor to strip and wax and buff commercial vinyl tile flooring in 6 Unit apt building.  

After about a few minutes with the windows and a candle it fades into the background.  

Unless I misunderstand your point.If you’re talking commercial real estate only, that’s a completely different ball of wax and I can’t say my points apply.Good luck with whatever you choose to do.

Inspired by @investorgirlbritt from Instagram we burned the candle at both ends when we could to get it done and not struggle to get our construction commitments done as well.

Its probably the wax ring in the toilet 10 bux,  or shower body,$150 really not a big deal.
