I heard this on a pod cast before where the investor buys 15 rentals, 1 every year for 15 years. 

If you're making 4.5% now, you'll pay more servicing the debt on a HELOC.

And also, since I am the borrower, am I correct in my understanding that I would be subject to a tax on cancellation of debt which would lower my total IRR.I saw many years ago (like in 2017) on BP that note investors were shooting for 10-12% IRR in a zero-interest rate environement. 

Hey Ben,Congratulations on getting started!

.### Other Considerations- **HELOCs (Home Equity Lines of Credit)**: You can take out a HELOC on each property or on a few properties to pull out equity.

They are excellent tenants who have taken care of my property very well and have paid rent on time every month since August 2022.

@David N.there are some  lenders that  can go to 90% ltv on vacation home purchase  (  .....benefit on rental prop purchase is that you can use  a portion of the new property rental income to help with qualifying if needed ...pricing is similar for  2nd homes and rental properties 

From a tax point of view, is it possible to move his money from his business account into a real estate purchase without paying tax on the money from his business account?  

You have a liability coverage on both. 

Looking at return on investment and cash flow of the property itself.
