Can't comment on the residual value, but for practical sense ... install gutters WHERE NEEDED. 

I'd always wanted residual income so buy and hold rentals intrigued me.  

Tenants cover debt plus residual for repairs, etc...Interest write-off is appx. $60,000 per year. 

For example Wolf ranges have a 8 months lead time, so I need to order them when I start, windows have a longer lead time than usual due to residual effects of covid and supply chain, so those to I need to order ahead of time (by that i Mean a head of what is normal) All I can say is I am doing everything a person can do, to make sure they dont go over budget and time.

One is they only allow it to offset the PITI/expense and then any residual income cannot be added to your gross income.

Well the sensor fell off the door jam and I needed to use superglue instead of the adhesive it came with.

Most likely will be splitting monthly CF by %, as well as, residual equity by % also.

You'll also have some additional rent money in the IRA, my guess is you have a residual 20-25% value that you'd otherwise pay Uncle Sam just taking the hit today... 

@AJ Shepard I've had a residual interest in the appeal of real estate for a long time, but I've only fairly recently become completely obsessed.

Certain businesses I can't own due to moral complications etc. and how I feel about it.The more I think about it the more I am leaning to a no on businesses.If I keep income streams to three then I think I might have the life I want:- Closing transactions with my commercial clients- Buying commercial property directly for myself- Starting a fund or syndicate to go after retail turnaround properties.Even when you make a lot of money it's all about the residuals so they come in no matter if you are working or not.
