There is a practical limitation - a cost seg does not make much sense for under a million of asset value, maybe you can go down to half a million..Grow your portfolio and do it later.

I just learned about the cost segregation study, and how it can save an investor a lot on taxes.

@Marc YoungYou should not do your own cost segregation study.

Quote from @Connor Chanter: I have a couple rentals near Milwaukee, I'm looking to do a cost segregation study to accelerate depreciation and recapture some bonus depreciation from the last few years.

There are a lot of factors to consider when get a cost seg study to determine if the benefits outweigh the costs.

Not everybody can:https://www.biggerpockets.com/forums/51/topics/1121063-expla...Assuming that you can use more depreciation, here is a very generic snapshot of how your situation might turn out:- land: not depreciable at all- land improvements (fences, driveways, landscaping): 40% bonus- personal property (appliances, carpets, cabinets): 100% Section 179 or 40% bonus- the building itself: no bonus, slow depreciationIn order to break out the components I mentioned, you will normally need either a cost segregation study or a detailed breakdown from your builder, plus someone qualified to do the sorting.  

You can get a cost segregation study that will also apply the renovation work that you did.

Your time spent studying LLCs and holding companies would be better spent studying a market to find purchases!

Instead, you can unlock 100% bonus depreciation on assets with a useful life under 20 years.This includes:•Furniture & appliances•Flooring•Window coverings•Landscaping & outdoor lighting•Fencing, driveways, and patiosThese can often make up 20–35% of the purchase price — all potentially depreciated in Year 1 with a cost segregation study.Cost Segregation Friendly Features = Faster Write-OffsCertain property features allow you to break down the building into faster-depreciating components:Look for:•High-end finishes (luxury fixtures, lighting, smart tech)•Pools, patios, outdoor kitchens•Detached garages, ADUs•Upgraded appliances and built-insThe more non-structural components a property has, the more value a cost segregation study can carve out into 5-, 7-, and 15-year buckets.Newer or Recently Renovated Homes = Richer DepreciationNew builds or heavily renovated homes often pack in:•New HVAC systems•High-efficiency appliances•Premium flooring, tile, and cabinetryNot only are these attractive to guests — they’re also gold for depreciation, since they’re assigned shorter useful lives and can be depreciated more quickly.Higher Purchase Price = Bigger DeductionsIt sounds obvious, but worth repeating: the more expensive the property, the more there is to depreciate.A $1M STR might yield $200K–$300K+ in bonus depreciation in Year 1.

As @Ryan Coon has mentioned, a cost seg study may be viable if you qualify for the STR loophole.
