@David KrulacWe routinely use triple glazed windows, mostly vinyl or fibreglass, but where historic conservation guidelines demand, we've used wooden framed windows.Quad glazed windows are comparatively new and offer more variation in configuration (evenly spaced, spaced in pairs), but unless they are in an insulated fibreglass frame, the benefits of the extra glazing will be marginal and definitely not cost effective.  

I would choose the granite, as the natural color variations add character, but what do I know? 

I would like to do some variation of a house hack in San Diego (ADU/SFH-MFH conversion/small MFH rehab).Browsing Real Estate Websiteshttps://www.zillow.com/savedhomes/for_sale/17084059_zpid/1_pnd/33.17664,-116.814881,32.687353,-117.553025_rect/10_zm/1_rs/1_fr/I was looking at Zillow last Friday and found this listing (it is now pending sale), and thought "maybe this single story 5/3 could be split into 2-3 units?"

Also, I've never told anyone of this strategy even though I knew others were doing it to with different variations of it.

Most hard money is a close variation of this theme, at least from what I've seen and used in Utah, California and Nevada.

You may see slight variation in color due to fading, but it shouldn't be too bad, especially since it isn't a color.If the shingles are old enough to be brittle, this may not be a workable option.

Do you say to yourself "Ok I have to do these 3 things everyday to stay on top of it" or some variation thereof?  

How does the offer process work, paperwork, any differences and variations you can explain would be helpful?

Even within the same region, you'll find a lot of variation based on the specific lender and even the specific underwriter assigned to the file.To everyone working with FHA buyers these days, when you find a good lender/underwriter, stick with them, and encourage all your buyers to use them.

The neighborhoods that support rehab and flip are often too expensive to cash flow very well for landlords.A rehabber is likely going to base his purchase price on the 70% rule or a variation of same.
