Many opt for other investing methods in their SDIRA like private lending, crypto, private equity...anything except collectibles and life insurance.Note that a Solo 401k is exempt from UBIT on leveraged real estate so if you have self employment activity and no full time employees save for you and your spouse you should consider the Solo K as an option. 

Most who opt for section 8 are purchasing in the lowest barrier neighborhoods where section 8 is the best of bad options.

There a ton of great DSCR options you can find on the Lenders tab at the top of the page, or connect with an experienced broker who can shop all the best lenders for you and educate you on the best options out there.

Even then, all of my booking.com clients are American I offer a 25% discount 0-3 days out. add a 15% fee which essentially covers your commission. set up with one hour to cancel, flexible / strict option but no refund 60 days out or later. sync it with Airbnb and or the other ones you are doing.

I’m new to all of this and looking at 401k loans and HELOC as options.

That's how I would propose it as an option next time.

Quote from @Edgar Duarte: hi allI would love to get some perspective from your expertise, we have a property that we would have to sell in 2025 to avoid paying taxes on the capital gains, we believe we rcan sell it for $700K and get an equity of almost $500K after paying the mortgage balance, if we invest all of it option in index funds at 7% rate (standard com growth calculator), or in more rental properties as we are all here for, I can get the equity of around $900K.option B would be keep paying the house at 2.3% int rate while we have it in AirBnB and maybe sell it in 10 years for $900K, knowing that we would be paying taxes but it is not that bad still. or we can 1031 at that point?

I assume mountain towns are my only option for cooler in the summer without humidity. 

Using a HELOC for the down payment on the second home might be an option, but lenders may require you to wait a few months post-closing on the multi-family before approving new loans.The BRRRR-style approach could work if you can renovate and refinance quickly, but make sure the timeline aligns with your lender’s requirements.

Aim for a credit score of 680+ for better refinance options.
