For me it's more a debt balancing act opposed to an "all in leverage strategy."

During due diligence I took a look at the rent history and the tenant has a balance of a little over $1,000.

Then you pay balance on the sale amount usually within a week for free, within 30 days with 10% interest - and wait till the deed is ready You can during that time to ask your title company to do the search and extend the title insurance but it's not for mechanic liens or taxes - you'll pay all that.That's why it's important to research the property through before you say "bid".  

Bathrooms especially are difficult since their small size makes it hard to justify a separate inside unit.

He and his wife now moved onto base but they did not give us their new address and this seems to be the difficult part for us. 

This will teach you the ropes and keep you out of trouble.The only "difficult" parts are1.

The agent-client relationship needs to have trust and it is difficult to build this online without social proof. 

Every payment grandma gets, as well as fees and PMI, is tacked onto the mortgage balance.

You only have the one so it should not be too difficult.

I'm not sure what size MF property you're looking to acquire, but if it's under 5 units, I think it would be difficult to find someone willing to lend to an LLC at a reasonable rate.
