@Garrett Brown let’s hear your success story .why would a passive investor looking for a fixed rate of return of 15% Cash on Cash want a variable return via co-hosting?

So all variables are significantly more costlier. 

If  you are in the 20% range, you are better off going to the casino and putting all of your money on black and seeing what happnes.Since you are out of the area properly calculating cash on cash returns can be difficult because you have variable expenses to calculate. 

Sorry to be a wonk, but the reason is that many expenses are semi-variable.

But I will counter some.When we talk larger checks, there is a lot of variability in what that means

I ended up comparing it to the bigger pockets BRRR Calc and everything checks out besides a few variables.

Most realtors I know have several roofers they work with--there's huge variability in the ones I work with so getting a few more quotes might help. 

I recommend you do this annually to adjust for utility increases and other variables.

I do think the variable rate avoids refinancing costs vs fixed, but again, you’re betting on rates there with a lot of risk on the variable side.Super interesting product.

@William Coet, as Jackson noted, there are too many variables to even begin.Two things to remember, any tax losses you utilize to offset incomes, will reduce basis making bigger tax bill in sale year.
