I'm going to try leasing the place out myself again, but if I'm struggling, I will hire property manager. 

A lot of landlords use platforms like Zillow Rental Manager, Apartments.com, or Avail to list vacancies and screen tenants.

This is a question for your attorney and accountant on how you will manage the company etc.

Investment Info:Building a Fix and Flip/Wholesale Active Income Arm of Our Business.Routinely have 5-10 active flips/wholesale deals under management/in process.

Ive been using the same for many years now and its my foundation for operations, follow-up, workflow management and communications. 

Additionally, it provides investors with the opportunity to add a unit on a property they already own, simplifying management since the new unit is in the same location.Finding a vacant lot is both expensive and difficult, so the ability to build, subdivide, and create new development opportunities can make financing easier.

Maybe you help manage the property for them for a small %, or give sweat equity for small cosmetic renovations?

Even though I wasn't a good asset manager, I made money on my properties. 

Sorry to hear your self managing isn't going as planned...finding good tenants is tricky!

It's best to have a house manager.
