I have three apartment units and I can't figure how to find a buyer?

I have a client that has three 6 bedroom pool cabins already having booked 121, 111, and 167 nights for 2020.

I am a pediatrician in Eugene, OR, married with three children. 

I knew I wanted something that was half or mostly commissioned, so I've already looked over my monthly expenses and made cuts where possible.My personal savings account is not quite where I'd like it, but our rental account is strong and self-sufficient; I don't even count my cash flow after reserves.

I picked up three units for a great price. 

I held several properties as rentals for many years then started selling them off - holding the contracts of course.It got me started with very little money, grew the cash fast, and provided me with passive income and financial independence in just three years.

The tenants were so surprised that three things happen:1.

I am interested in single family, duplex, three flats. 

Over one week, there were 78 inquiries through Zillow, 2 through Craigslist and 53 through FB Marketplace.We held an open house (5 families showed up) and then decided to pre-screen using a Google Form and schedule viewings for reasonable prospects (with sufficient income and no pets).

Because life is funny, three weeks after settling in to my home in South Carolina I was offered a full time job in New York so I moved back to NY and rented out my house.
