Most real estate investors have never heard of IOS — Industrial Outdoor Storage.

Room42.io is one — around $525, built specifically for residential investors, and it includes optional CPA review if you want that extra layer.

However, I want to clarify how room42.io aligns with the IRS Cost Segregation Audit Techniques Guide (ATG) while maintaining a much lower price point.1.

Especially after iOS 26 update, people are reporting response rates have dropped.

Apples to Apples - Yes of course the scope has to be the same, but go deeper.

I like maximizing my cash-flow so I took a 2 year prepayment penalty on a 10 year IO and after the loan payment I should be paying cash-flowing about $1900 a month. 

Pros and cons with each lender that have to be weighed:  Rate, prepayment, amortization or IO, closing costs, and reserve requirements.If you decide to refinance, I'd recommend seeking out credit union quotes before committing to an agency deal and weigh those options against each other.   

DIY platforms (room42.io and similar) start around $500 and can work well for straightforward residential. 3.

If their $300k comp needed a full reno and yours is turnkey, you're not really comparing apples to apples.

A normal rate buy down can be expensive in comparison to doing an IO period, especially if your plan isn't to keep the home for too long.
