When your tax professional prepares your 990t they will utilize the Cost Seg to minimize the UDFI tax. 

Of course, after that brief interaction, I'm pretty sure I just become lost in a sea of other text messages.My question is do any of you see a way to utilize a strategy like this?  

My neighbor is renting her Jr.attached ADU: 2 bedroom, 1 bathroom, 825sq -furnished- $2500/mo (utilities incl./ current tenant renting for 6mo).LOFTI have plenty of land for detached ADU /their own yard, driveway & entry with the goal of a 1 bedroom/1 full bathroom downstairs & a bedroom/powder room upstairs <so 1 & 1/4 bath>...

A couple of things in regards to saving on taxes by utilizing depreciation correctly.

The key is finding a reputable house-moving company in your area that can handle permits, utility disconnections, and logistics.

See when materials get delivered, etc.This last one is debatable but It works for me.Not utilizing rewards or cash back credit cards during renovation projects to maximize ROI.

@Jason Porto6-12 Months of Expenses: Many investors aim to have 6–12 months of property expenses (mortgage, insurance, utilities, and maintenance) saved. 

All utilities are at the street. 

When there's tenants already occupying the property, there's often times different leases that were signed among the tenants.Additionally, renting by room usually sees higher tenant turnover which in turn causes more work for the PM.Other challenges to consider:- Disputes/conflicts among tenants (different personalities if a tenant doesn't know the others prior)- Occupancy limits- Splitting utilities (what if someone uses more water?)

Since you said both units are rented, I'm assuming you are utilizing the LTR strategy?
