@Tyler Kress not trying to diss your family. Heck, mine is the same way. But everything you do in your life is up to you. They likely learned the hard way like we all did about screening tenants or even worse. Didn't learn. I would for sure have some sort of property management company or programs to handle tenant complaints. Buy at least in an LLC for tax purposes. If you incorporate in Nevada you can move in and none of your tenants would even know you own the place. (Not soliciting but my attorney is barred in for Nevada feel free to pm me if you like.)
Landlording can really suck. You'll likely have at least 1 bad roach infestation in your own personal unit. People are loud and sharing walls sucks. You'll have at least one or two "professional" tennants that slip by and are just there to rob you and make your life miserable.
Sadly until you have 20 units and are golfing at noon on a Monday you won't be able to change your family's minds.
I remember more than once having to burn my clothes along with an entire house full of stuff with my dad because it was just... gross. Bug infestations, moldy food, fridges full and electricity shut off, pets that have never been outside or had a litter box, you name it.
My folks got burned so much they gave it up. My realtor is my dad's girlfriend so he knows any time we even look at a potential rental. He thinks I'm absolutely insane because all he remembers is horrible tenants with no respect for themselves or anyone around them.
He hasn't seen how nice it is to have a clean rental in perfect shape with a clean and respectable tenant.
My advice? Hands down take the ~12k profits from the sell and the 10k. 22k down on a 3.5% FHA loan is roughly a $650,000 multifamily. I forget what it's called but you may even be able to borrow along with that for repairs.
You'll never win the game if you don't play. And as young as you guys are it may be tough to be taken seriously by lenders. But from your post you already sound like you've put more effort in than some of the "successful" investors i know. Go for it!
