How Do You Get a Bank to View HML as Cash?

[Josh Carter]

I found another great short sale deal which I offered asking price. I put down cash and used my Lending Home HML Pre Approval letter as my POF. The selling agent is saying that this doesn't count as cash and says bank will count as a mortgage and deal must be cash only. Lending Home says theyve done numerous deals and have never run into this problem. I'm wondering if this is why I keep losing out to the other offers I've made this year. Can anyone give advice on solutions?
