Your strategy of re-marketing a 3-bedroom plus office as a 4-bedroom home office is a smart way to boost rental demand and rental income without major renovations.One insight I’d add is the potential benefit of exploring cost segregation studies once you build a larger portfolio.

And you can also put an inflation adjusted dollar figure on each one as well as a timeline when that money might be needed.

Theres many benefits being well capitalized. 

Real estate should at a minimum get you 6% Cashflow + 8% appreciation  and 2-3% in mortgage paydown all based off a 25% down payment.Yes sir, those are all benefits not always talked about in the real estate investing world!  

Reason being, I like to manually adjust a few things, items where i see more or less LT inflation. 

Additionally with further rate reductions, many mortgages originated within the past two years would likely benefit from a refinance to then current mortgage rates. 

I think it's a great way to enjoy the benefits of your investments without triggering a big tax bill.

If there isn't one present, has anyone seen any ROI benefits of the installation?

@Salvatore D'Agostino Sounds like you've got a solid grasp of who does (and who doesn't) benefit from Cost Seg and are looking for info specifically about the Cost Seg process and results. 

Providing them with ample notice allows them time to plan and adjust financially.
