I think, though, that it's important to look past it and actually analyze expected rent vs expenses and mortgage payments.

In the DSCR world, there's more than a 1% difference between a 70% cash out refinance and an 80% cash out refinance and with that increase, the rents may not carry the mortgage payment at 1.25%. 

Rookie here,I'm possibly looking into the BRRRR method on an SFH or duplex.

How can you use the BRRRR method when don't have 5-600k to buy a single or multi-family all cash in these areas? 

So unless you have 20-30% for the down payment on a 5 -50 million dollar apartment building/complex, then you are going to need to raise money for that.

Can i purchase land and offset the mortgage payment against it as passive loss and wait for real estate prices to go up and hold the property.

The funds will be used for my down payment and the rest will be used as emergency funds.

There are plenty of apps out there that can make paying bills easier, and peer-to-peer payment tools (Venmo, Zelle, etc) make it pretty easy to add a description so that you know what they payments or for.

That is the preferred method.

I would have no information on the person other than the passport, the deposit, the cash payment, and the lease.
