When I check local real estate listing it’s evident that a number of these properties for sales are former airbnbs that were purchased in the last 2 years and clearly are not worth holding onto for the owners.

Hey @John FriendasI have purchased 4 of my Co-Living (rent by room) properties with DSCR, 1 of them within the last few months.Not that I necessarily recommend this, but there are short-term-rental DSCR products.

Look for motivated sellers off market and market via cold calling and or direct mail, geofencing, advertising and the like.A good wholesaler is as @Ericka Parrott mentioned, direct to seller, did good underwriting and can deliver an actual "Deal" whether buy and hold or flip. 

Quote from @Cade Antonucci: I am starting to grow my rental portfolio and am looking for online alternatives to hold security deposits.

Turnkey, buy-and-holds, flips, or something else?

Investment Info:Small multi-family (2-4 units) buy & hold investment.

@Eric Smith A 1031 exchange with a related party is possible but comes with strict IRS scrutiny and holding period requirements.

Be clear on terms—percentage of equity, profit-sharing, and exit strategy.

What is your finance mechanism and terms?  

The result is typically less loan proceeds, lower rate, worse terms, etc.
