You need someone like James Wise to chime in on this for management tips, if he has 2 seconds to spare. 

Hey Ingrid, I use gas grills and I have a propane tank connected to the grill and I have a spare just in case.

A lot of the companies can run a report to show you the numbers if there are other rentals in the area.STR's Condo's pretty much manage themselves and you can probably do it yourself if you have a little spare time as a learning experience.

I was doing reviews for a specific company as use for gaming demos due to it's compact size and LED/Laser light source.

It's a pain but the post office has a sytem set up for it.I told the tenant I couldn't do anything for him until AFTER Memorial Day and after that I would figure out if we had a spare and get back to him, , but I told him to in the meantime, call the post office, hold the mail, and manually pick it up, and keep looking for the key.

At one point I incubating other businesses in spare space in my office as an equity opportunity.I don't like the term arbitrage.

Spend your spare time reading, listening to podcasts, analyzing property, studying the markets, etc.2.

Aggressively review opportunities in your limited spare time and scale up as you gain experience.

Seems pretty easy to setup.You could add a feature to a spare room or game room or whatever with little work.

I spared some details but its closer to me than just "a seller".
