@Chris Gomes as Erik mentions, your goals need to be defined first.  

I am targeting duplexes in a defined zip code. 

If you have a defined capital need and don’t mind paying principal and interest from the start, with less flexibility, then a cash out refinance may be a better option. In some areas, and with some lenders, HELOCs and cash out refi‘s on investment properties are becoming harder to find, but well worth it in my opinion if you can get a good lender with good terms.

You could search for the various apartments/condos/homes that are available in the defined area and in this case, you’d most likely have to connect with the listing agent to get you in touch with the landlord themself to propose those sublet thru Airbnb idea.Lastly, you would have to find the individual landlord’s contact information and contact them directly asking if they’d be open to having you sign as the tenant and sublet their property out thru Airbnb - seems very difficult.I’d like to hear what others think would be the best way to connect direct with landlords to pitch this idea of subletting thru Airbnb.

we are both RE professionals as defined by IRS.

When you get over 100 units, now you're managing a team of a leasing agent, maintenance man, etc.Let's define your goals specifically so we can give better advice.

It’s an app that allows you to create a filter that defines what properties meet your company’s criteria.

That door, from what I'm reading, is where the apartment ends.As an FYI, this is supposed to be defined by the lease.

Multi-family is 5 or more as defined lenders who enable the transaction.

@Jessica Piff Well Jessica it sounds like you have thought through everything and have your reasons for doing this well defined.
