After a quick drive by of the property and some online research, I submitted my offer and it was executed by lunchtime.

Does anyone know of free online resources or price per report resources? 

@Max Bellino For smaller properties like your 2–4 unit multifamily buildings, an online cost segregation study is a quicker and more cost-effective option, providing sufficient accuracy for straightforward properties.

My opinion is that these builds will be super high end and expensive, but with affordability guidelines will bring online many income restricted units to add to the mix.Overall, I think the message is now resonating with public officials that we need SUPPLY over any other approach to address our housing crisis.

As @Ke Nan Wang said you have to hire an architect to make these decisions for you.On my projects I will compile like 5-10 inspiration photos based on projects I've done in the past, comps, and photos I find online, then I'll present those to the draftsman/architect.

But if you want to understand the concept of "non-qualified use" in the context of Section 121 exclusion, there's a mountain of information online, including this Bigger Pockets forum.

I use QuickBooks Online for all of my clients.
