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.

I figured its a win win, they get to invest into some real-estate and grow their retirement as well as it will lighten my investment and potentially allow me to get into a better property that would cash flow/appreciate better.Does anyone have personal experiences or opinions on this?

It could very well be the route that is "cheapest" now, ends up being substantially more expensive down the road.If the costs above are not worth it to you...maybe pass on the LLC and get yourself a good insurance policy, and maybe an umbrella policy personally.

However, (personal opinion) I do believe that the Beltline represents a real, physical asset that will help values stay strong in the long term (assuming you don’t overpay).

I know in the sense that you’re referring to this being your personal house with your personal belongings, but even potential renters are disrespectful of other peoples houses.If it’s muddy outside, don’t be shocked if they don’t walk around the outside first before going on the inside without taking off their shoes at the door. 

So far, we've pieced along different elements of this (different tax person each year, no LLC to one to now 2 this year, haven't yet used a bookkeeper...)trying to streamline systems and have a solid foundation for our fairly new and growing real estate portfolio. 

Some buy and hold investors may have outdated beat up buildings that can't be sold conventionally without repair and your flipping operation with the right agent may just happen upon that deal for working with that person.

Quote from @Jason Watson: Other people in the lending space might have better answers, but some lenders quote taxes, insurance, etc. to fully understand the monthly cash burden and ensure you know it as well. that is correct Jason, I personally like it better like that so I can actually see what my payment is after everything is said and done. 

Are you buying to house hack or rent out both sides.There are so many personal questions to answer, before you begin analyzing deals.Factors such as jobs, population, tenant laws, median income, affodability, crime, schools are all metrics to considerGood Luck!
