I started out with a flip house and am currently focusing on long-term rentals.

Spruce the place up and put in a new tenant.I also recommend you read some books about managing rentals.

I wouldn't partner with anyone privately on a rental property.

The exception would be if this was already permitted for STR - short term rentals VRBO then it might be worth it based on location.If you just want to buy a home and have a unit to help cover the mortgage I would still insist on lower price point or NO HOA to help get the total mortgage down so that the other unit covers 50% of the overall payment.  

Does anyone know if I am able to start an LLC and run short term rentals?

@Mark Peeples it's buy and hold and rent out to tenants as a mid-term rental unit.

But again, I go through the questions about and decide based on the level of stress/work, cash flow utilization and my overall goal for that rental and make my decision.

I turned my former personal residence into a rental and have it listed as such, with occupancy coming up within the month.

We are purchasing land in OBX and have a great builder lined up to build us what should be a tremendous rental property.

Are you talking an airbnb type of rental, or are you talking about housing people- such as forever renters- who may have a job, or may be relying on governmental help for all they have?
