It's not quite as easy as renting out two sides of a duplex, but with the right marketing and management you could rent out the extra unit to supplement the mortgage payment. 

However, I don’t yet have the funds for a down payment on another house, and I’m trying to figure out the best option for where to live while I rent the apartment.Do you have any recommendations for managing this transition or tips on finding a temporary place to stay?

Do you work with a property manager or do you do everything yourself?

I'm managing D class properties with a property manager and am making a profit. 

Yup, property condition, vintage, neighborhood, tenant base, property management are all very important considerations. 

@Isla Arshad,  you've described the experience of many landlords who manage their own properties.

I would be interested in connecting for the Washington team position for both purchasing agent and professional property management.

Logical Property Management are actually my property managers.

I would consider getting out of property management and getting into cleaning IF you think they are doing better than you . 

Find a good property manager that you can bend their ear.
