This was a local buyer.  

This is true for every jurisdiction in the state but of the local jurisdictions I am only aware of the city of San Diego having indicated a duration (12 months).  

Some ways to find that person is local Real Estate Investor Facebook groups, local Real Estate Investor Associations, Realtors who list multiple properties for other investors, Bigger Pockets website's forum, and local property managers.You will also want to try to get on the buyer's list for local real estate wholesalers.To Your Success!

@Kegan SchollFrom my experience, if you're a 22-year-old house hacker, Texas and similar markets can be great for room rentals thanks to population growth, strong demand, and tourism.

Quote from @Ray Joseph: If you attend a local meetup, I'm sure you'll find investors that operate in other cities or states.And you have thousands of out-of-state investors to mingle with right here!

You picked a great community to join.. have you checked out local comps to gauge the market vibe yet?

These can provide good cash flow and are easier to manage than larger commercial properties, especially when you're just starting out.Also, when I was starting, I found local meetups super helpful.

When I had located this particular duplex I contacted a local agent to represent me on the acquisition.

Reach out to a LOCAL property manager that knows the rental market BEFORE you go under contract! 

In my local MLS, they would be listed in the 2-5 unit category.
