Here is a rough "rule of thumb" for the effect rate increases have on buying power:
Each 1/2% increase in rates reduces buying power by about $5,000 to $6,000 per $100,000 borrowed. This very rough rule of course depends on property tax rates and the total purchase price.

Red Pear Realty gives up to 2% back to buyers in the form of a buyer rebate. This can definitely help buyers out as they'll be able to use the rebate on closing costs and buying down their interest rate.
