Maximize discounts with a multi-property purchase?

[Joshua Tikal]

I am looking at two properties next door to each other which if I could get a 33% reduction I could be at 1% rent to loan. One of the properties has been on the market for 5 months and the other 2 months, both are identical specs.  Do you have any experience \ success in making an offer on multiple properties in order to gain higher discounts?
