With those in mind, would a portfolio purchase get you there quicker, maybe. 

Your original purchase is depreciated over 27.5 years.

The second is a rehab property that I purchased for myself, I purchased it out right for 100k.

Purchase price: $175,000 Cash invested: $35,000Buyout property that needed significant upgrades to bring to rental market in 2022.

Purchase price: $640,000 Cash invested: $220,000 Purchase price $640,000Got it at this price because there is a non-paying tenant in unit 2 (rent value $3,500), we're in court Rehab $60,000All in cash (rehab plus down payment) $217,500Rehab included ground level basement and 2 parking spot drivewayMonthly cash flow $1,500 ARV $950,000Equity $470,000Refi cash out (August 2024) $150,000 (used to buy new rental)New monthly cash flow breaking even (non-paying tenant still in unit 2)New equity about $200,000

It's only dead if you are spending too much on your purchase.  

Assuming you purchased in your IRA for cash as most do, then there's nothing to deduct or depreciate because the income is non-taxable inside the IRA already.

@Wade Wisner -  Most of the notes that we purchase we keep in our portfolio and borrow against them with private capital.

Purchase price is $210,000.

I have several CFO clients that do similar heavy rehab projects in the Midwest (albeit with a lower purchase price), so you can definitely make the numbers work.
