Can I live in my garage and rent out the rooms in my house?

By the time you're 30 years old, you could have 40 doors if you purchase one 4-plex a year.

Even if the door seems to be locked, it the bolt did not go back smoothly, it will be reported as jammed.We got our first smart lock fairly early-on and it jammed constantly, causing us to have to change the batteries much too often.

Write them a letter, track down their phone number to call and/or text and knock on their door.

Is there a digital door lock whose code you can change remotely, without a monthly fee? 

All 11 bedrooms have their own bathroom, every bedroom door has an electronic lock.

Then all of the extra money you paid over that 5 year time frame gets washed out the door.

It depends...most carports without exterior walls/doors would fall under a 15-year property under asset class 00.3. 

Purchase price: $588,000 Technically a duplex but its a single family home with an ADU built into the home using the space above the garage as the ADU living space.

Also, the check-in process if very manual, requiring someone to handover fobs to unlock the door.
