My shingles were installed that afternoon. 

Roof costs say $8000 (depending on size, shape, type of shingles, etc.) and last 25 years (depending on weather, type of shingles, slope, etc.) ... that's $27/mo you need to put away in CapEx to eventually replace the roof ... now do that for all the systems in the property, add them all up, add some reasonable amount of margin, and you have a reasonable grass roots estimate of what your CapEx should be ... code it into excel with the approriate parameters such as square footage, number of water heaters, etc. and you can knock out a CapEx estimate for a specific property in a matter of minutes, without messing around with bogus rules of thumb like 50% rule or 10% of gross rent, or any other such thing that tries to relate things that are completely unrelated in order to shortcut around actual thought and analysis.Any calculator that you do not understand all of the inputs, outputs and assumptions that went into them are less than useless, and BPs are no exception ... therefore the best ones will be the ones you build yourself from the ground up and modify over time as you gain experience and find that some of your assumptions, inputs, and formulas need tweaking.  

What would you guys suggest for a paint color with brown soffit/facia and light brown shingles?

Also I occasionally do a tear off and shingle a roof. 

We took off 3 layers of shingles & 2 layers of cedar shingles on one property & it only leaked because a tree branch went through it.

Now, those Tesla solar shingles are a different story. 

Creme/Tan with brown garage doors and brown shingle roofs? 

The inspector said the foundation was as flat as you could ask for, the only problem with the roof was a single missing shingle, and that in general this place was in extraordinary shape for it's age.

I feel like it was a rip-off, because they bought it for $39k, painted, screwed tin over shingle roof, and put in granite countertops, then charged me $119k.

Well, you know I couldn't get matching shingles without waiting 4-6 weeks, and bad weather was coming up, so I put a whole new roof on.
