Good morning Kimberly,
If a home is on the market then it's there for you to present an Offer to Purchase! When you state the "house is in foreclosure," does this mean you have found a home for sale (on the market) that is a foreclosure or does it mean you have knowledge of a home in foreclosure?
If it's the former, then have your Realtor prepare a written Offer and begin the negotiating process. If it's the latter, then you won't be in a position to buy the home until the bank (or some other entity) buys it at auction and puts it on the market.
An important note about foreclosures: the "Asset Manager" at the bank that owns the home may have a bottom line number she needs in order to sell the home.
I have noticed of late that Asset Managers have become slightly more flexible when negotiating with Buyers. Some banks are actually effecting minor repairs in order to facilitate a Purchaser obtaining mortgage financing. HIstorically foreclosure properties have sold to all-cash buyers. But with a large inventory of foreclosed homes, and the fact that cash investors will only buy with a substantial discount off list price (because they're paying cash), I believe that more Asset Managers are realizing they need to be more flexible with Buyers obtaining mortgage financing.
Put your best foot forward, make your Offer and begin the negotiating process.
If you thought my answer was helpful, please give me a "Thumbs Up." Thanks!
