Similarly, I am currently depreciating an HVAC system I installed several years ago so wouldn't the remaining undepreciated amount be added to my adjusted (carryover) basis (using either the general or simplified methods) after the exchange is completed?  

Ability to DIY (or subcontract) repairs w/near zero overhead/margin.2. 

So I’m in a bit of a bind, I have a duplex I’m house hacking we remodeled entire thing, new hvac, electric panels, electric main, updated plumbing, water heaters, furnace, install central air, roof.

Another benefit is the ability to dispose of a component like the old roof when a new roof is installed. 

Just a couple of years ago, many PMCs and DIY landlords required an application to schedule a showing.Days on Market are up over 38% in the last 2 years, so many are becoming more flexible to get more activity on the vacant rentals.

I've done a couple small projects (drywall, painting, shower installation) with Fox Construction recently.  

I am installing wireless, ten year lithium battery combo smoke and carbon monoxide alarms in my rentals. 

My first thoughts is to install keyless doorlock, ecobee and make sure kitchen has everything needed by guests.

I spent a lot of time to find the locks and now need manufacture to come out to install the lock5.

I too would look into a fence installed by a professional and ask the tenant to share the expense.
