The other bonus with multi-family is that a lot of people rent them out for a lot lower than market.  

The study identifies with forensic engineering detail the immediate Bonus Depreciation 5, 7 and 15-year personal property class lives qualifying portions of a building that are normally buried in 27.5 year residential or 39 year commercial categories.The Cost Segregation Study was performed on the Asset Depreciation Range (ADR) and is based on a 40% tax bracket for State and Federal Taxes.

On the MLS you will see words like "excercise room" "bonus room" "finished basement with walkout space" kinda thing.

So, the property drop just increased my cash flow, without raising the rent.The beauty of this method is two fold:1 - You never ever spend the principle, since every refi allows you to get it back.2 - You never need another source of funds, since you can use the same funds until your arm gets tired.3 - Ok, I said two, think of this a a big bonus.  

Also, you want to search for other terms, like guest house, bonus room, mother-in-law suite, separate living quarters, etc.

I agree that some of those - garage, storage, are definite bonuses.

Hey guysAs most of you know by now, there is a STR loophole that lets STR owners get huge tax savings via bonus depreciation. 

I only have one STR and I am not a high income earner at my W2, so I am trying to accomplish this so that it makes financial sense just for my one unit.Topics of assistance-cost segregation, bonus depreciation, active participation and my logging hours, home office, offset W2, schedule C etc.Thank you in advance,Austin Spitzenberger

@Brian Jasinski keep in mind bonus depreciation is phasing out these next few years unless we get another legislation change so doing the cost-seg and STR loophole won't be as lucrative as it once was.
