Someone is going to be very unhappy if they have a tub filled with sewage.

Best advice is to partner with someone who specializes in investment properties in the Austin area.

Can someone easily explain best way to leverage my new property, etc to be able to get a 2nd, 3rd, etc by only using my properties as collateral?  

Are there strategies, financing tips, or resources you’d recommend for someone in my position?

Not that it really matters.No institutional lender will give someone a loan that doesn't have:1) Credit history2) A social security number3) Income3) Employment historyYou'll want to research Wholesaling and Land Contracts.

It’s always exciting to connect with someone diving into long-term and mid-term rentals too.This is a great place to network and learn.

Finding someone with the expertise to screen and place tenants properly is rare.

Rarely does someone respond.

But given I've paid for snow removal like once ever, I don't know what I should offer someone who is not a "pro" and already has an idea of their rate. 

I'd also worry about the showings and if someone steals something from the tenants.
