My recommendation here: Walk on this one and cut your teeth on a smaller deal you can afford solo(to build experience+credibility), or work on finding an experienced partner who can lend support to the deal.

But they are fully amortized and if your buying a low value 3 to 5% rule you can handle 9% compared to 5% with no difficulties whatsoever... your just paying a little extra for opportunity costs....

For the record, I have no desire whatsoever to hold real estate in my retirement accounts.

Potential tenants have no imagination whatsoever.

If they are missing teeth, and the have ripped clothes, your apartment will end up the same.

Now, if the seller has funds and is willing to pay down the loan and do a Sub-2 you may have the same results, I'd think in either of those cases that would be as rare as hen's teeth.

I  just thought your comment didn't help me whatsoever. 

I bought two empty lots in the Oakland Hills in 2004 for $79K and sold them around 2009 for around $624K total, absolutely no improvements whatsoever.

No phone calls whatsoever.

Contemplating all future rentals will be no pets whatsoever.
