I'm hoping tenants don't start pushing back on needing a physical key.

So a nicely decked out  cabin I bet would rent real well for STR purposes  Not sure about permits etc..

Obviously you will also want to walk all of the units physically during your due diligence period to see the condition of the apartments inside.

Trying to go to companies directly is rarely going to be your best bet. 

It looks like networking and meeting people will be my best bet.  

Bonus depreciation is just a special part of the US tax code.It allows you to take accelerated depreciation on portions of your property depending on when an asset is put into service.At the time of this writing, you can write off a huge portion (60% in 2024) of many qualified components that have a useful lifespan of 15 years or less.That means a certain percentage of things like landscaping, sidewalks, latches, appliances, fences, certain flooring, etc is depreciable in year 1.The bonus depreciation rate percentage changes yearly depending on the administration and the tax code.For years 2015 through 2017 first-year depreciation for all the items on a 15-year schedule or less was set to 50%.It was scheduled to go down to 40% in 2018 and 30% in 2019 and then 0% in 2020.But then Trump got elected, and he enacted the Tax Cuts and Jobs Act.That moved the bonus depreciation percentage to 100% from 2017 to 2022.In 2023 it went down to 80% and it’s currently at 60%.Depending on who gets elected again, 100% may be back on the table.Only time will tell.We know that the US government wants to incentivize more development and ownership of RE.They want Americans to continue to build and maintain our physical world.That’s why real estate is one of the most tax-advantaged assets in the US.Depreciation and bonus depreciation for RE are very positive and will likely continue in the years ahead.

I'm betting your numbers look like mine, and CapEx saving is eating up a lot of it.

Doing this like a brrrr I see as the best bet, for example my property does still have room for improvement adding a bedroom and bath to the primary structure and then the ADU.

The safest bet is to try to get a variance from Union City. though clever, your combined unit lease agreement would likely cause trouble if ever scrutinized by the Tenants or the municipality. 

It's how it goes in physical asset investing.
