We rent and treat our tenants great expecting them to stay for 5 years.

The original six month tenant I had extended the lease 9 times and stayed a total of 5 years, paying me about $15k over market rent annually.  

However, if you choose to stay there for a bit and sell you'll get the first $500K of profit tax-free if you've lived in it for at least 2 out of the 5 years prior to sale.

Therefore, I don't have definite plans for how long I'll stay in Oregon, and consider the possibility of someday returning to the Austin area.

There are a lot of quirks and oddities in Louisiana law where the current tenant can assert that they have an implied agreement that they can pay late, stay X months without a lease, do whatever action, etc, based on what the current landlord/owner has allowed and told them in the past.

Stay there one night and test it yourself.

Meet other investors in your area and stay in touch with them; you can ask them questions that might prevent problems.Best to you!

You need to polish your skills, bigger pockets is a great place to start... find a local wholesaler you can work for/with and he will guide you. 

Short term rentals are legal when the host is living in the same apartment as the guests and there are no more than 2 guests staying with the host."

Preferably stay for one year and find another house.
