DSCR is going to be high right now, but if you buy a strong asset, let it marinate, rates come down in 2 years, rents go up, you could be in good shape.

If that doesn't yield any results, I would advise you to lower your expectations for high leverage. 

All of my cycling friends are highly motivated people.

Small multi-family is in high demand. 

I have been looking at high single for SFR BTR. 

I understand it is a difficult market at the moment (High interest, High prices, etc), and I have no problem playing the waiting game.

Paying down a mortgage quicker gives advantages if you believe the appreciation outlook is high because the debt pay down will give you more benefits when the property appreciates.

Potentially, but highly unlikely.

@Joseph Turner, if you're looking to buy in CA areas with high levels of appreciation, I've had clients take out a HELOC or 2nd mortgage and pay back the HELOC or 2nd with a cash out refinance once values appreciate. 

The big brokerages do offer great support, but your fees will be high.
