Do you plan to purchase the property in an LLC or your personal names?

Also, I agree with @Dave Van Horn about earned income vs passive.The way "around" this is to buy the property in an LLC and do a DSCR loan.

But there are a few other perks too, especially for investors:Speed & Simplicity: Less paperwork since lenders focus on the property’s income, not tax returns or W-2s.Scalability: Easier to grow your portfolio since it doesn’t tie up your personal DTI (debt to income ratio).Flexible Ownership: Many lenders allow you to close in an LLC, which is a big plus for asset protection. 

My property manager Casey Nichols with Heritage Realty LLC is phenomenal.

For instance, holding the property in a limited liability company (LLC) that leases it long-term to a separate C Corporation LLC handling STR operations may reclassify income to avoid self-employment tax.

We do have a partnership LLC together on this, to add.

A series LLC would be extra unnecessary IMO.

For example, you could hold the STR property in one LLC, which then leases the property on a long-term basis to another LLC that is taxed as a C Corporation.

While it is true that in the past lenders were happy to trigger the due-on-sale clause, this has not actually been the case in recent years due to some LLC-friendly changes in servicing guidelines published by Fannie Mae and Freddie Mac.

Once the property is sold, then the PML is removed from the LLC.
