It's slow to build a portfolio on just W2 income, but however slow it is still life-changing, lastest for your retirement.

Is there anything I might do to accelerate the release of the funds?  

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.

Slow and steady for me, though!

I have gotten inquiries about a slow cooker or an air fryer even. 

Rates are NOT high right now historically speaking. https://fred.stlouisfed.org/series/MORTGAGE30US   Sure, we have gotten used to historically anomalous low rates, but that does not mean we will get back there without the economy slowing down.

However, since market shift / rate increase even these guys have slowed down quite a bit.Regarding regulation, I think eventually Indy will have to regulate against Short Term Rentals.

Per trading desk they said "yeah, crazy right, a lot of people are gonna get caught sleeping on this one", as in when market has that cycle it will get "interesting" when the forced sells occur accelerating the drop, that those in the know have algorithms built and set to grab the bottom.

Due to item 1, adding an ADU can require years to start achieving any return (once the accumulated cash flow recovers the initial negative position).4) Adding an ADU is a slow process.

If you know what you're financially capable of then you can pare down your research to those markets/projects and accelerate your investing.
