Renovated with cosmetic updates for immediate rental income, it offers strong cash flow while preparing for more extensive repairs and the addition of an ADU.

Needs extensive work but don't know true extent.

Anyone investing in a product new to them is never going to have perfect knowledge going in; extensive knowledge is accumulated over time, and, well, if you wait for perfect knowledge you’ll never invest.  

I added value to the deal by initiating cosmetic repairs to make the units rent-ready while preparing for more extensive renovations.

I am also planning more extensive renovations to modernize the home, which will further enhance its appeal and value.

Happy to have a conversation as I have extensive experience working with non-US citizens.

It was quite extensive, all new electrical, hvac, plumbing as well as foundation, painting, floors and yardwork and demo of shed.

Maybe the work is so extensive that it won't make them a profit?

Extensions are likely granted, if needed.You will receive $3k relocation assistance at the end ( unless you have other liens, back due water/sewer/HOA etc. ) You can also stay in the home until the sale closes, which gives you at least a few months payment free to be able to figure out where you will relocate.

You can always ask your tax pro if you're unsure.To give you an idea, I built an extensive flow chart for our bookkeeping team to help decide if something should be capitalized or deducted for a rental property and this became our SOP for capitalizing vs deducting.
