I'm a single mom, working a full time job and side hustling as a photographer (real estate and portraits) and I'm really motivated but I don't have time or money to get steered in the wrong direction.

While there’s nothing inherently wrong with this, there is something to be said for shaking things up every once in a while.

They manage both Single and Multi for me. 

Our preference would be not to sign anything tethering us to a single agent, but have it be an open secret with realtors in the area that the house is available-Any insights appreciated!

However, if you can find a single tenant with good income and background I would go that route. 

@Calus GlispieA single $1 is point blank disrespectful.

That's a lot of questions for a single post, @Andrew Caldieraro, but here goes with at least a couple of answers/suggestions.  

Wife and I are getting ready to make first major purchase and I wanted to share something that happened.After many months, I finally convinced my wife that the road to success will require us to downsize from our nice $250,000 single-family home in North Central San Antonio into something more modest, like preferably a live-in duplex or four-plex.

And you need every single one—if ONE of them refuses, this strategy fails.

I had also read that a single member LLC ( with foreign nationals) is disregarded in the US and subject only to personal income tax.
