to add onto what @James DeRoest said, in addition to ongoing sealing you have to do to maintain it (which you probably don't want to entrust a tenant with), granite is porous (like wood or skin), so if a tenant spills wine, or oil, or grease, or meat sauce, or fish guts, or chicken innards, or other liquids that can stain, those liquids seep into the pores and may not come out if not properly attended to, leading to discoloration.For B class tenants, the ROI is not with it.

You SHOULDN'T need the guru-hype and skin-in-THEIR-game offered by those expensive classes!

Have we become that thin skinned as a culture already ? 

Unless you go with hard money lenders, in which case you'll need to have more "skin in the game" (money).

For the sauna and a couple of closets - where it isn't apparent if the light has been left on - I installed switches that glow with a red light if they are left on, prompting folks to turn them off.If you have an old hot tub, look into replacing it. 

More skin in the game.

Partner (syndicate) with a small group who have skin in the game and who's own capital is on the line, and know this - THERE IS NO SHORTCUT - whether you have $2M or $20MKeep the BP fam updated with your journey and findings, so we can all be a little wiser, and good karma will come around to serve you well!

I have heard that sometimes lenders like this, because the seller has some skin in the game as well. 

You need a lot of money for marketing, you need to know what cash buyers are asking for in the area, and you need to know how to quote a job for repairs well.I don't think you can joint venture and buy fix and flip easily either.Many Hardmoney lenders will be looking for "skin in the game" and experience in rehabs.So where is the opportunity right now?

@Justin Koehn In addition to my wifes reply to you, I would add that we have some cash to put some skin in the game so we want to take action immediately.
