Search the Montgomery County sheriff site for sheriff sales. Foreclosure takes a while as the banks are really trying to work with people who need help. But if the foreclouure notices have been sent, the house will first be sold at a sheriff sale.
You can log onto your county auditors website and plug in the address and a lot of time it will have it listed as Auction and you will be able to look up the tax records. This should help you a lot. Normally they also send a certified letter to the address of the property as well.
